Training in Cold Sucks

Yesterday I went out in 50 degree cloudy weather to go do some climbing laps on Kings Mountain and Old La Honda. I did not anticipate the temperature drop on top of the mountain, which combined with the wind chill factor did me in.

Clearly I did not dress correctly. My exposed finger gloves and half covers for my shoes weren’t enough to prevent near frostbite on them as I zoomed down Kings after my first climb. I think the wind chill was in the high 30s and my body was starting to really shut down. I considered going to Old La Honda and doing that once but it was too much. I went for the fastest way home as I felt like my body just couldn’t give anymore and didn’t want a total shutdown out on the road.

I made it home and stood in a hot shower for many minutes to get warm.

Suck.

I hate training in cold. I’m already of low body fat such that low temps are just uncomfortable. Keeping warm during cold day workouts just saps me of extra energy keeping warm. It also increases the risk of getting sick too. I remember forcing myself to go out for 6 hour rides back in late 2004 to prep for my first Ironman NZ. I got sick a few times but also during those cold rides I never felt like I never could really push hard because so much energy was used to keep warm.

Time to watch the weather better and just wimp out more and enjoy longer focused interval rides on my Computrainer.

Gua Sha and STARR Tools

I just went to my physical therapist and he turned me on to some tools made out of plastic, which were very much like metal Graston tools but much thinner. I doubted that they could hold up to the abuse of scraping my muscles, but after a treatment session, they seemed to hold up fine. They also exhibit another vibratory quality than thick stainless steel; you can feel and hear the vibrations of the adhesions and bumps within muscles much better (so thick stainless steel better than a spoon, but plastic better than either).
These are the tools of Gua Sha, whose roots are in China now in the US. In China, these tools are often made of jade, or bone, or animal horn. When I first mentioned Graston to my mother years ago, she told me that the Chinese had been doing this kind of treatment for a long time, probably longer than Graston has been around.
Gua Sha stands for “scraping sand” and that’s what you do with the tools, which is to scrape your muscles. The principles are the same as Graston although the explanations are often in Eastern concepts, using qi and energy meridians and flow. My PT person told me that he went to a seminar and the teacher who is a Westerner had also incorporated a lot of other concepts, like the concept of Anatomy Trains where muscles are linked together around the body and often treating the entire muscle chain is much better than treating just the local affected area.
Gua Sha scraping can be light up to super deep, resulting in a bruised appearance lasting many days. My PT person and I talked about this and we both feel that extensive bruising resulting from super deep scraping is bad for people in-season. I’ve often felt the results of deep Graston the next day when my muscles are too traumatized to perform well, even as they are healing.
For a more in-depth discussion on Gua Sha and its usage, pick up this excellent book from the Gua Sha Tools website. It’s packed with lots of detailed information, and crosses from Eastern and Western philosophies.
I did want to mention that I found a Graston tool substitute that was better than my spoon. A few weeks back I searched the internet looking for, perhaps, a set of used Graston tools on ebay or elsewhere. Amazingly, I could not find one instance of a used set anywhere! But after much searching, I found the STARR Tool. The website is a bit ghetto as far as design goes, and with anxiety I pressed the Buy link to purchase the STARR tool. Thankfully, it arrived a few days later!
The stainless steel STARR tool is excellent. The steel transmits the vibrations much better than a metal spoon I was using and it has multiple edges to be used on various parts of the body. Its heft really allows me to get into muscles deeper too. It also comes with a CD that goes over the basics of scraping technique.
While I admire Graston very much, I also like the fact that people are getting alternatives out there, especially for an adventurous soul such as myself who dares treat my own ailments. I can’t get into my PT person’s office all that often, and between visits, I bust out my trusty STARR tool and help my body along in its healing and recovery process.
I did buy a set of Gua Sha plastic and jade tools, so once I get them I’ll do a post on how they feel relative to my STARR tool and Graston as well.

Intermediate to Advanced: The Different Types of Training

In my interactions with my coach M2, I have learned that there are 6 types of training. These are:
1. Neuro-muscular – training of the nervous system to do something either differently, better, or to some form which maximizes efficiency and minimizes effort. Example: super short high speed treadmill intervals for 15-30 seconds per interval, form focus workouts for swimming.
2. Speed – training that results in being faster. Examples: swimming speed sets, sprinting track workouts for running.
3. Strength – training that results in you being stronger, and to put out more energy at the same effort. Examples: hill climbing in running, hill climbing or more watts on the computrainer in cycling.
4. Endurance – training for the ability to race or produce energy output for some length of time. Example: gradually lengthening the duration of a long run over a period of weeks.
4b. Stamina – I make this a sub-section to endurance, which is the ability to maintain a level of speed/strength for a long period of time. Example: gradually increasing the time of your intervals and reducing your rest periods while maintaining the same wattages during Computrainer bike interval workouts.
5. Recovery – stimulation of blood flow by raising heart rate and circulation but not raising effort to flush the body of exercise by-products and promote healing. Example: cycling on a computrainer at negligible watts, but high RPMs for about 20-30min.
It is somewhat obvious that whenever you go out to train, you’re most likely training more than one of these areas simultaneously. However, I wanted to point out:
1. You can train to focus on only one of these areas.
2. It’s good to have a mix of all 6 areas as you’re building for a race. The mix depends on where you are in your training schedule.
3. You have to be aware that potentially you could be detracting other areas if you’re not focusing on these areas.
Let’s talk about the first point.
Focusing on one thing is possible and many times desirable. Of the 6 training types, I’ve focused on mostly neuro-muscular, strength, and recovery. It’s all based on what you individually need.
For example, over the winter, I did a lot of treadmill training where I’d warmup with track drills, ie. kick backs, skipping, and then started doing 30 min intervals at super high speed, building from 6 MPH to as much as 11 MPH (where the interval drops to 15-20 seconds due to the fact that the treadmill takes too long to accelerate to that speed). By the way, I have not found a gym treadmill that goes faster than 11 MPH, although I have heard that you can actually get treadmills that go that fast. What this achieved for me, is not necessarily the ability to maintain an 11 MPH/5:27 min/mile pace over a race. It does help train my neuromuscular system to fire my muscles quicker so that I get used to running at a higher turnover rate, at paces I can maintain. This results in me being faster simply because my body is accustomed to moving my legs faster.
For strength training, over the last 2 years I started climbing and doing laps on Old La Honda and Kings Mountain. These laps have built up my leg strength considerably and increased their resilience on hill climbs, where I was defeated utterly at Ironman Austria a few years back.
I am also a big user of recovery workouts. I figure out if, for a given workout, I need to back off. If I do need to back off severely, often I’ll do a recovery workout. An example of this is a pedaling efficiency workout involving a lot of high RPM one-legged pedaling drills at minimal wattage. It doesn’t stress my muscles from a power standpoint, but it raises my heart rate and circulation so that blood is flowing through my muscles and the flushing effect helps my recovery so that the next day I’ll be able to perform a normal workout.
Second point: The mix.
Training all in one type means that you’re not gaining the full benefits or reaching your potential for a race. If all you’re doing is sprinting workouts on the bike, you may not be able to last an entire century. If all you’re doing is running at endurance pace every workout, you may find that you aren’t increasing your speed, or you don’t have enough strength to pass someone when you want to.
You need to mix it up and include all types and improve on them all. You can figure out, as I have, where my deficiencies are, and do some focus on improving some areas. But overall, you need to train all 6 types as you build through your season to the big race.
I tend to focus on neuromuscular workouts during the offseason, as they don’t stress my aerobic system and are great for recovery workouts. Then I move from neuromuscular focus as my training season starts to building speed and strength with a lesser endurance emphasis. This is because endurance is easiest to build, but speed and strength take lot more time. As I hit mid-season, I am adding more endurance and stamina into the mix as I try to extend the speed and strength I’ve built up to longer times.
Third point, watch out for what you’re not focusing on and don’t let it slide.
As you’re focusing on certain aspects of training, you have to watch out that you don’t reduce other aspects. An easy example is that as you build endurance, you may find that your form (neuromuscular aspect) gets really messy as you get tired. This is very bad! The trick is to maintain form even when you’re butt tired, and as you focus on building endurance. Otherwise, you could injure yourself through poor form, as your muscles are tiring and you engage other weaker muscles to compensate.
Another example is when you’re supposed to be doing a recovery workout, but yet you feel energized and so you try to push harder and do something with more energy. But then all of a sudden, half way through the workout, you find that you burn through that initial burst of energy which fails you later because you weren’t fully recovered and you don’t have enough stamina to continue. Recovery when you have to and don’t force yourself to do something your body just isn’t OK for.
Yet another example is not gradually increasing your workout intervals to improve stamina. You mentally don’t feel like doing fast intervals beyond a certain point, and thus your stamina never improves. You hit race day and you find that as you try to maintain speed, you can’t and you’re slowing down as you move through the miles.
While training typically involves the simultaneous training of all 6 types of training, I think that there is a lot of benefit to identifying where your personal needs are, and coupled with where you are in your training season, you can focus on specific areas which need improvement and advance them greatly. Categorizing the different types of training really helps in thinking about training and how to race faster.

Giving up on Amphipod

I started using Amphipod bottles and belt on the recommendation of a friend. They do seem to have some advantages over FuelBelts: wider mouths on the bottles, belts seem to fit better.
BUT THE ONE THING THAT REALLY SUCKS is that the bottles don’t consistently clip in. Sometimes they go in quick, and sometimes I have to stop running and fiddle with it to get it to clip in. And sometimes, I can’t get the bottle to clip in at all and I just end up running with it for a while and try again later.
This is really bad. I could not imagine the frustration I would feel if a bottle didn’t clip in during a race, let alone a long training run.
Sorry Amphipod. I’m going back to Fuelbelt. No way am I risking a race on bottles that don’t consistently clip back into the belt.

How to Tell When to Back Off During Training

When I used to weight lift a lot, one of the things that I learned which was really important was when to back off during training, or just not train completely. You basically had to be able to distinguish between when you were just a little tired but you still could work out, and when you really shouldn’t work out like when you’re injured or sick or burnt out, etc. You also have to figure out when your brain is just being lazy and you can workout, even if you don’t feel like it.
Backing off during training can be a hard thing. We’re all hard charging athletes and we always want to give it our all for every workout. We follow what our coaches give us and if we don’t follow their plan exactly, then we get an anxiety attack and feel like we’ll never finish our goal race. If we miss workouts, we feel like we’re not gonna make it.
The reality is that you can have what I call “backing off” at the macro and micro level and still be fine for the race. Macro level is when you get sick or injured, and you have to take off multiple days (maybe weeks) to get better before you can go back to training. Micro level is when you either have to skip one workout due to some factor that will resolve itself within a day, like not being recovered enough from the day before, or extra soreness, or low energy levels. Whether you can have a great race depends on so many factors and not just if you miss a workout or two, or even for a week or more. Generally, backing off at the micro level, ie. taking a day off, skipping a workout, reducing pace/watts, etc, doesn’t have much effect if it happens temporarily. Backing off at the macro level for too long, ie. being sick for a month, taking weeks to heal a pulled muscle, being lazy on workouts for many weeks, etc., will definitely affect performance.
So don’t worry about it so much! Back off because you should and don’t stress about it. But do pay attention when you back off for a long period of time.
How do you tell when to back off? It took me a while to figure out how to tell when I should back off and how much. Here are some things I learned:
1. If I’m sick, then of course I should not train.
1a. But figuring out when I can start training again after being sick can be tough. When I finally feel physically a bit more energetic, I usually start with recovery workouts to get the body readjusted to training again, before leaping into full bore training. I try to keep workouts short, like 15-30 minutes, and not overstress my system until I’m 100% back.
2. I have tried to fine tune my sensitivity to my physical condition. This is intuition, and knowing how your body responds to stress and how fast it recovers, and a sensitivity to the condition of your muscles and overall system. Only experience can tell you what your body needs on that day. So keep alert and a log if it helps, and get to know your body as much as possible.
3. I find that the five key things to keep track of are your heart, lungs, muscles, energy level, and brain. Warning signs are when my heart rate is a bit high, or my lungs feel stretched still from an intense workout the day before (I usually feel what can be described as a “cool” sensation in the middle of my chest), or my muscles are sore or tight. Or sometimes my brain just doesn’t seem to have the same willpower as it may have on another day. Or my energy level is low and I feel tired. These all tell me that I need to be more mindful and potentially may need to adjust my workout to fit.
4. The easiest days are when I approach my workout and feel mentally fresh and my body feels energetic. The other easiest days are when my body is overly sore and I feel mentally and physically tired: an obvious sign that I should take a day off. The toughest are days when I am right about to workout and am on the edge of feeling not all that energetic and maybe I’m not fully mentally psyched for working out. But through experience, I know that often when I start the workout, my energy comes back to me when I start.
On days like this, I usually don’t worry about being lazy – it’s not really in my nature nowadays and I always look forward to working out. But I don’t know exactly what I can accomplish during the workout, and am not sure whether I can push the limits or just do a recovery workout, or somewhere in between. So I usually am prepared to adjust my workout midstream to what I can handle at that moment.
I find that it is during the warmup that I can figure out most of the time what awaits me in the rest of the workout. As I warm up, I approach my goal workout speeds (swim or run) and/or wattages (for bike workouts) and see how my body responds. If I am feeling like my exertion level is too high and unsustainable, then I know I’ll have to lower paces or wattages during the main set or else I will flame out before the workout ends. If I feel good, then I will be OK for the goal paces/watts.
Another potential factor: sometimes if I approach a workout feeling a bit tired, I can bring my workout up to goal paces/watts simply by having a longer warmup. By getting my blood flowing slowly with more time, I am able to get my system moving and potentially still hit my goal paces/watts.
5. If I make it past the warmup, then I may adjust again during the workout if something is not right. This can be a perceived exertion that is rising too fast for me to make it through the workout. It can also be a sapping of willpower that could evaporate if I am powering through some really fast paces or watts and trying to hold them for long intervals.
6. One macro level adjustment I have made was my recovery in general. By doing so many intense weekend rides doing Old La Honda and Kings Mountain climbs, along with a 2-3 hour run, I have found that I actually need another 2-3 days of recovery. Just taking one day off is not enough; I will do recovery workouts for 2 days after and then I’m fine on the 3rd day for a normal pace/watts workout. I know this because I have tried to sustain paces/watts after one day and my exertion and heart rate leap in the first few intervals.
Instead of fighting this, I just merely added it into my workout regime and it has not affected my race times at all; I’m still getting PR times race after race. It’s almost unintuitive that you could rest more but still yet race faster! I chalk it up to my age, my fitness level, and what I need to do to race faster.
The important thing to note is that we’re all different as humans. We all come from different fitness backgrounds and levels, and that coupled with our age and genetics means we can train a certain way. We need to develop a sensitivity for what our individual bodies need, and not stress about how others are training. I am a big believer in individualized training and I think this is where a lot of generic plans and group training can harm people. Developing an awareness of how our bodies work, and coupling that with a good coach (who won’t train you like you’re in the army and/or shame you into doing senseless workouts), will work wonders for your race performance.
So take a day off if you really need it or back off on the paces and watts – don’t stress about it and you’ll still race fine come race day.

Specialized Rib Cage Pro Road: Water Bottle Cage to Hold Gatorade Bottles

At Ironman Florida, Gatorade was the sponsor. During the bike, they handed out those Gatorade bottles that resemble water bottles. They have this twist close top which you can suck fluid from. However, annoyingly, they have a smaller diameter than traditional re-fillable water bottles and normal water bottle cages don’t hold them securely. Upon a light bounce of the bike, they go flying much much sooner than normal water bottles. This annoyed me to no end as bounces are accentuated by the XLab Flatwing where my cages were attached to, behind my seat. The only place I’ve found that holds Gatorade bottles is in the cage attached to my seat tube, where I usually keep one in case of hot races where I want to grab a 3rd water bottle and keep it in reserve between aid stations.
However, I did see one guy who had some cages that seemed to hold Gatorade bottles tight. The unfortunate thing was that I totally forgot the brand of the cages I saw!
I finally searched around for cages that might hold Gatorade bottles. Normal ones just don’t cut it. You can bend metal ones to hold them, but then inserting regular water bottles re-bend them back to not holding Gatorade bottles.
Remember: I start with my own water bottles filled with my own formula/fluid. During the race, I pick up extra Gatorade bottles to supplement fluid when needed. So the cages need to accept both regular water bottle diameters and the lesser Gatorade bottle diameter.
I went and bought a Gatorade water bottle and brought it to my favorite bike shop, Cupertino Bike Shop, to try out a few cages. I think I found the right cage: The Specialized Rib Cage Pro Road.

It grips nicely onto the gnurling around the Gatorade bottle, and also somehow can expand to hold both normal water bottles and Gatorade bottles.

While no cage will entirely hold bottles securely on a big bounce, these should hold them in more conditions than regular cages. With many races having Gatorade as a sponsor, I am glad to have found these cages so that I can feel good about putting them on my XLab Flatwing cages instead of only in my seat tube cage.
If only Gatorade would make their bottles the same diameter as normal water bottles…

Notes:
1. The net distance on the entire set is about 1000-1200 yards/meters. Total time to finish this workout is probably about 30-45 minutes depending on what I did after the main set.
2. I swim this workout on a 25 yard pool.
3. I started in the offseason and swam this workout 2X/week. It allowed me to focus on one arm swimming strength alone.
4. I would warm up with 400 EZ swimming, then jump into this workout.
5. I did this workout with fins, to give my body an extra push and not let me wallow in the middle of a lane when I got tired.
6. Following this workout, I would either do sprints of 50s, or pull with paddles and do 25 EZ/25 sprint alternating for about 200y. At the later stages, I would sometimes just cool down after the main set because my muscles were too tired. I did not attempt to force my tired muscles to do anything else afterwards, as I considered this a strength only workout and didn’t tie in any other elements like endurance. I would focus on that during other workouts in the week.
7. The stress on my muscles was quite high, especially after I crossed the 200y mark of 100 right arm, 100 left arm. At the same time, I started into the base phase of my training too. That’s when I started doing this workout once a week, and swimming normal Masters workouts another 2X during the week.
8. When you’re one arm swimming, you can really focus your attention on the stroke and pull of each arm. I really put my attention on each and every stroke, and try to make each one the perfect stroke and be able to repeat it through the entire set. What’s the perfect stroke for me:
a. Body form – Keeping as straight as a needle. I try not to let my flutter kick ruin my body straightness. I lay on one side and don’t let my body sway or rock. I relax and think that I am a log just floating on the water and just paddling the log.
b. Head position – I keep it aligned with my body. I don’t lift it up during any part of the stroke (another thing I found out I was doing!) but keep it in one place. I put my cheek against my bicep to maintain form and also close up the gap between my face and arm to prevent a possible place where drag from water can occur. I had to experiment with how deep my head was in order to keep my hips from dropping lower. With my body composition, I believe that my head is actually lower than many instructors might want it. But I also try to keep my forehead slightly up to cut through the water better, versus having the water barrel over my dipped head and create drag.
c. As my stroke enters the water, I try for the most quiet, non-bubble creating entry into the water. I am most successful with my right arm, not so good with my left arm. It has been talked about in other literature that creating bubbles wastes energy, and also is evidence of a messy, energy-using entry into the water. I try for perfect entry every time.
d. The moment it enters the water, I extend fully and almost immediately catch. The catch is when I bend my hand downward to “grab” water. Following next is my forearm bend to catch even more water, but as my forearm sweeps down, I also feel the actually stroke begin to work. I make sure that I bend ONLY at the elbow and keep my upper arm high. I don’t let the entire arm drop down deep into the water. This is evidence of getting tired and also will create more drag as the deep water presses against the arm.
e. I keep my elbow high as I pull back the arm, down the length of my body. I try to keep the elbow skating along the surface of the water, or perhaps less than an inch under the surface as I move my arm/hand back against the water.
f. I try to keep the stroke strong through the entire length of the stroke. In the past, I discovered that my stroke would always start strong, but then fizzle out towards the end. So I focus on using my big lat muscles to pull back and not my shoulders, which are small and would get strained. As my hand/arm passes my shoulder and towards my hip, I start thinking about using my tricep to sweep the water back behind me with the final extension of the hand. This is where I had the most problems, where I was losing energy at the end of the stroke and was just letting my hand just drift backward and not using energy to get that extra push at the end.
g. I focus on keeping the hand/arm pressing straight back against the water, and putting 100% of the backward force into exactly forward motion. In the past, my arm was drifting up and down, and even moving backward in a circle when it started getting tired. Your tired arm will start to move around in order to find the place of least resistance to move backward; this is bad! It needs to push against the area of resistance that creates 100% forward motion. I focused on making every stroke put 100% of my energy into going forward EVERY TIME.
h. The only thing missing from this type of workout is the addition of your hip roll into the force of the stroke. I only lay on my side swimming and don’t attempt to add my hip roll to give extra oomph. I focus on arm only and do not rock my body at all. I work on adding my hip roll during normal swimming.
9. It’s OK to repeat workouts until you master it from a muscle standpoint.
10. I found this workout to be extremely demanding on my swim muscles. I need adequate recovery afterwards, which is at least a day in between until my next swim workout.

One Armed Swimming

Every now and then, my swim coach would make us do what he called the “scooter drill”.
You take a pull buoy and hold it one hand in front of you, as you swim with one arm for a set number of strokes. Then you switch hands and swim with the other arm for a number of strokes. It’s sort of like getting on a scooter and pushing constantly with one leg to make it go.
It’s also an annoying drill because no one is used to swimming with one arm generally.
I hated it. As I swam down the 50m length, I would be OK for a few strokes and then I start getting tired, and get slower and slower, until I’m totally wiped out just reaching the other wall.
I grew determined. I wanted to be able to do this drill, which others seemed to do OK and seem to be so fast going down the length of the pool.
During my off season, I started doing intervals of swimming with each arm for 25m. I would successively increase both the number of intervals and the distance I swam with each arm. I eventually reached swimming a 400m with one armed swimming for 200m each. I would then do other shorter intervals for a total of a 1000m set. I would do this 2-3X a week during the off season, and as I entered into the base phase, I would do this once a week while swimming normal workouts the other 2 times.
As expected, my “scooter drill” improved greatly. I got much faster and fatigued a lot less, as I was working out with one arm a lot longer than the scooter drill intervals. But another more amazing thing happened; my regular swimming got a ton stronger and faster.
One big thing I suffered from was that my stroke would kind of fizzle out at the end of the stroke, near my hip as it exitted the water. In doing one arm swimming, I was now able to keep my stroke strong through its entire length, and for longer durations. I could still be strong swimming for workouts up to 4000m. In addition, I was able to lower my stroke rate and thus not be so out of breath and/or wiped out AND my swim speed increased.
One arm swimming really bummed me out. I rallied, took matters into my own hands, and improved my one arm swimming ability in a focused manner. But then I realized the benefits of this strength increase in both endurance and speed.
Yes….amazing!

Stopping Muscles from Cramping Up

A friend and I were IMing one night about her muscles cramping up. I thought that it would be interesting to write a post about it, since in my early triathlon career, I suffered from cramping in the most inopportune times during races.
I read an article in one of the popular triathlon magazines that talked about the causes of cramps and what can help prevent them. It actually showed some evidence that electrolyte supplementation didn’t help prevent cramps. Then there are all the medical research into what happens within muscles to create these painful situation. Of course, each coach and athlete has their own formula for preventing and managing muscle cramps.
In this post, I’m gonna skip all the scientific stuff and talk about my own discoveries. Note that everyone is different, and I think that applying a systematic way of figuring out why you cramp and what can prevent it can be your formula for success.
What causes cramps?
What I’ve found causes cramps are:
1. Electrolyte depletion. I sweat buckets in general and that just causes electrolytes to flow out of my body. This increases during warmer days, and seems to be less of an issue during cooler days. During races, I always build up this layer of grit on my skin, which is just the salt buildup from sweating so much and for such a long time. Thus if you don’t replace electrolytes, you’re more likely to cramp. So those who get dehydrated during races are really susceptible to cramping.
2. Over-contraction of muscles, especially muscles that are already tired and/or tight. My classic example of this is trying to stretch tight quads during a race. You reach down to grab your ankle and pull your leg back towards your butt. But since your hamstrings are also tired, they seize up in a cramp while trying to stretch your quads! Needless to say I NEVER stretch my quads now during a race. Another example is when I swam last week, and for some reason my plantar fascia was very tight. Then I shoved that foot into a fin and swam a long set with fins. The plastic boot on the fin was snug, but it also squeezed down on my foot so much while I was kicking that it caused my whole foot to cramp up. Not fun.
3. The muscles just get overtaxed and overworked, and thus cramp in protest, despite your mind willing the body to do more. This has happened to me early in my triathlon career at half and full Iron distance races. I have found two instances why this happens. The first is due to simple pushing of my body, typically my legs, and then towards the end of my race I cramp up because they are tired and I’m trying to either go faster, or go up a hill, etc. The second has to do with imbalances in my body. I have found that I naturally exert more of my right leg because it’s stronger than my left. This tires out my right leg more so than my left, and thus it can cramp up whereas my left is still OK.
What can prevent muscle cramps?
1. Electrolyte supplementation. Depending on how your body is, it could be that all you need is to drink Gatorade instead of water, or you may need take electrolyte tablets several times an hour plus electrolytes in sports drink and gels (like me). It varies widely between individuals and also in race conditions. I’ve been able to back off on electrolyte tablets during races with cool conditions successfully.
2. Get stronger. I would say that along with 1, this is the other really important measure for preventing muscle cramps. By really focusing on getting stronger during training, I have found that this has been the other major factor in preventing my muscles from getting to a potentially cramped state. So lots of hill repeats, and practicing accelerating up hills, for both running and biking. This also applies to interval work, especially on the bike, to extend the duration of maintaining watts while pedaling.
3. Kinesio tape. The curative/supportive properties of this tape are amazing. By taping from insertion to origin, you provide a slight tug to muscles in the “resting direction”, which helps muscles to relax and reduce the possibility of cramping.
4. Sportlegs pills. This amazing supplement helps minimize the production of lactate and exercise by-products in the muscles. When there is no “burn” in my muscles, it helps them stay relaxed even when tired and/or when I push hard. By not having exercise by-products in my muscles, they stay less tight and less susceptible to cramping.
5. Heat acclimatization. Adapting your body to function at high effort in hot weather helps your body figure out how to function under those conditions and not cramp, or just plain collapse. It learns how to sweat and to deliver energy and oxygen to muscles during hot weather, which is critical if you’re going to race during super hot days.
To discover what worked for me, I started experimenting. I didn’t do any kind of special blood testing. Suffice to say, it took a while to figure out what would work and what wouldn’t.
I started by upping my electrolyte intake during races and found that I got up to 3 Saltstick caps per hour, plus 2 scoops of Endurolyte powder in every tall water bottle, plus a scoop of First Endurance EFS. I also take a Powergel every 45 minutes, with its own set of extra electrolytes. I also take 3 Sportlegs capsules every 3 hours, and it’s amazing how I can push hard and barely feel any burn, but only just a general tiredness in those muscles. This works for me and keeps me going during races.
But I didn’t feel good about taking all that extra stuff, even during training. So then I made sure I got my body more adapted to the high stress of racing. I made sure I did negative split training on every long run, or would descend during loops up to 3+ hours. I did up to 4 laps up Kings Mountain and Old La Honda, which just toughened my legs to biking at continuous hard effort for long periods of time.
Then I also started running mid-afternoon, when temps were highest. I ran 3+ hours in 90+ degrees for many weeks. It was tough at first, but quickly got easier until I was able to run and do negative splits and descends.
It worked wonders for getting me through races both faster and cramp free.
A bit unscientific, and a collaboration of many different things I’ve read about or been told about. But I can’t argue with the results either.

Bike Benchmark with the Computrainer and WKO+ Software 1/5/2009

At the start of the season, I took a bike benchmark test to set a baseline from which training levels would be calculated. We used a Computrainer hooked up to a PC to record the results. The course I used was a flat 10 mile course so that I did not get distracted by hills. WKO+ by Trainingpeaks software pulled up the data to produce the results shown below. The test was:
Warmup for about 15 minutes
10 minutes at highest maintainable, even intensity, knowing that I would have to do another 10 minutes afterwards at comparable intensity
Rest 3 minutes
10 minutes at highest maintainable, even intensity, comparable to the first 10 minute block.
If I did this right, the average watts and effort should be similar to the first 10 minute block. If I overdid it on the first 10 minute interval, I would show a marked drop in watts on the second interval, potentially meaning I should do this test again and with better pacing.
The results of the 10 minute intervals are below:

Larger WKO+ graph screenshot here
#1
Time 0:00-10:00
Average wattage 203
Average HR 173
Baseline HR 168, but then rose to 180 as i neared end of 10 min
Highest HR 189
RPE 8->10
#2
Time 13:00-23:00
Average wattage 192
Average HR 174
Baseline HR 174, but then went to 180 as i redlined
Highest HR 184
RPE 9->10
I used the heart rate ear clip, which got super flaky on me clipped to my ear which got sweaty during the warmup and caused the readings to fluctuate or disappear entirely. On a whim, I clipped it to my finger and that actually worked better, although I found that for best consistent results I had to keep my finger as still as possible. For the future, I ordered a HR wireless strap and adapter which should improve things dramatically. I also need to replace a chip inside the control unit – scary!
I paced myself OK, close enough that I don’t need to re-test. I did go out a bit hard on the first interval which cost me on the second interval. Making to the end of the second interval was really tough and I found myself going up and down in watts as I would lose concentration and energy and need a small recovery.
My lactate threshold HR is probably around 173-174 or so and seemed to have drifted upwards from 172 which was from a benchmark test many years ago. My 100% effort workout wattage is around 195-200, which was what I suspected as I did many of my coach’s workouts computing workout watts from a 100% level of 200. This seemed to work well with me and getting through workouts with effort but not flaming out.
By the end of the season, I hope to do one or both of two things, which is to:
1. Raise my 100% level.
2. Increase my ability to maintain a higher watts over a longer period of time, like a race.
