If you look around training programs, you’ll see that there are two camps for coaches: those that give you training programs by distance, and those that train you by time.
If you don’t know the difference, it simply means that some coaches and/or training programs tell you to train by swimming/cycling/running a certain distance per workout. The theory is, that if you hit a certain amount of distance at the right time and amount, you’ll be able to complete a race. Training by time, in contrast, focuses on being out there and swimming/cycling/running for a certain amount of time and not be concerned about the exact distance covered.
In moving from beginner to intermediate triathlete, I have found some interesting elements to training with either:
1. I started training for my first marathon by training with distance. As a beginner, I think that training by distance is more advantageous to you than training by time. This is because you don’t know exactly how long it will take you to complete a race. WIthout knowing, you may be under-prepared for a race if you trained using a time system geared towards more experienced athletes because more experienced athletes will be able to cover more distance in the same amount of time. By actually going the distance, you can train your body and mind to know how long it will take to complete a race, to prepare it for surviving the distance both mentally and physically, and to know what will happen to your body, joints, and mind for being out there that long. Otherwise, you’ll find out at the race itself and it could be rude shock to your system, which I feel is totally unnecessary if you had prepared sufficiently.
2. Once your experience with racing grows, you get faster, and you start knowing your body better. You can then start moving towards training with time, knowing when you can approximately complete a race. You can just train with quality up to about that time and you’ll be prepared by race time. An example would be when I was training for Ironman Brazil and I would do these 30+ minute hill repeats up Old La Honda, which was only 3.3 miles to the top. I would do enough hill repeats to be out there for 5 hours, but my total distance would only be about 50 miles. But yet this gave me enough fitness and strength to complete the much flatter Ironman Brazil bike course of 112 miles in 6:15.
3. With swimming, I use a combination of distance and time. I swim one 45 min, one 1:30, and one 2 hour workout each week to prepare for Ironman. Each workout varies in distance depending on the workout itself. But I know that in my 2 hour workout, I will cross 4000+ meters which will be sufficient enough to complete the Ironman swim.
4. When training for triathlon, the cross training factor really helps. All the mileage I put in on the bike really translates to fitness on the run. Thus, when I peak for Ironman, I usually am swimming a 4000+ workout, riding a 6 hour ride and do a run of 2:45 in the same week. All that saves me from killing my joints and needing to run 3+ hours, which some training programs tell you to do. In that 2:45, I usually reach a max of 16-17 miles; hardly the 21-24 miles that some training programs tell you to do. But I know that the cross training effects mean raised overall fitness and I don’t have to go the actual distance.
5. Knowing your race times means you can train for that time, and not worry so much about distance. For example, I know that I can ride the 112 miles of Ironman in 6-6:30 hours. Thus, if I ride with quality (not just cruising) for about 6 hours, I know I can complete the 112 miles of a race without actually covering 112 miles in training.
6. By the way, you can’t be cruising in training with time. You need to train with quality and smarts and not just think that if you jog or cruise the time, you’re going to be OK when race time hits. That happened to me during Ironman Austria. Thinking that I could just ride the same rolling hills course to prepare really screwed me when I got to the hills of Austria.
Switching from training with distance to training with time was a real signal to me that I was getting truly familiar with my body and fitness level, and knowing what it takes to train for Ironman without overdoing it and risking injury.

If you read the books, you’ll find some info on recovery. They talk about the fact that you should take one day off and work out for six out of seven. On that day off, they recommend that you do absolutely nothing. Then they talk about getting rest during the week, like getting enough sleep at night, and eating after working out to replenish your fuel stores. If you get hurt, they tell you not to do anything until you are healed. After races, you should take about 4 weeks off after an Ironman, and about a week off for other shorter races. Post-race recovery is often described as little or no activity, maybe some active recovery like light cycling, swimming, or jogging. And that’s about it.
In learning about recovery for myself, I’ve found that it’s much more complex than that, and books don’t explain this to you, and neither do many coaches or so-called experts. I’ve found that recovery is a fickle thing, and varies by many factors and even across a race season.
First, I do take one whole day off each week and I don’t do any training on that day. I find that it’s a good thing to rest the body and mind completely. The other days are the usual regimen of doubling up on some days and not on others. I usually like to bike singly, and swim and run on the in-between days. Then on Friday morning, I go for my long run. On Saturday, I go for a swim, long bike, and then do a short brick run after.
But I have found that on really intense, long days, which for me means my usual 4000+ meter swim, and then long bike doing hill repeats upwards of 5 hours total or more, and then I run as fast as possible for about 20-30 minutes after that, sometimes stretching that to an hour, that after these long Saturdays I rest my Sunday, but then on Monday I’m still wiped out. In fact, the intense workout leaves me drained for about 3 days afterwards.
Sunday is complete rest day. Monday mornings I have tried to workout but I can tell I am not recovered because I hit my LT very quickly and cannot maintain long tempo sets. Even on Tuesdays, I still reach LT very quickly and cannot do fast workouts. Instead of panicking, I just go with the flow. On Mondays I sometimes swim a short set, like 1500-2000 meters relatively easy. Then I jog a recovery run on the treadmill, or do a form run. On Tuesdays, I do a low wattage pedaling efficiency workout on the bike trainer, which is varying sets of one legged pedaling. Basically, it’s two days of active recovery as my body gets back to being able to stand higher intensity workouts. By Wednesday, I am ready to do a more usual swim workout of 3000+ meters, and then I usually run track or a long distance tempo run and I’m pretty much back to my old self at that time.
Given my age and my fitness level, this is just the way it is. I’m 41 and I take longer to recover. I am also trying to improve my speed so that requires more intensity. But my body can’t take that kind of intensity without rest. And believe it or not, I am still getting faster despite needing more rest.
I also find that “rest” sometimes doesn’t mean just sitting around, watching TV and doing truly nothing. A lot of people talk about active recovery but don’t give enough talk about how effective it can be. I believe that the other reason why I get faster is because I employ active recovery instead of just sitting around. I believe that active recovery does two things:
1. It gets your blood pumping so that you can flush your system of lactic acid by-products, and get nutrients to muscles that need it. You’ll be amazed at how much better you feel if you are sore the next day after a workout, just by doing a light workout.
2. It trains the neuromuscular system of that particular sport’s movement, which enables you perform a particular athletic movement better. When I do active recovery, I always keep this mind. I do form runs, cycling drills, or swimming drills for active recovery so that I’m not just moving about. I keep the attitude that I am training, even though I am actively recovering. Many people go out for a jog, but don’t really concentrate on this aspect. They just go out but don’t use the time as training time.
Another example: the day after Ironman Half Vineman 70.3, my legs were really sore, and my body ached from the hot race day prior. I didn’t feel all that good, so I went and got on my bicycle trainer and proceeded to do a pedaling efficiency workout. After 30 minutes of that, I got off and noticed that my legs were not sore anymore, and my body definitely felt looser and didn’t ache so much! So that old rule that you should just take off a week after a race isn’t really that accurate. In fact, I would advocate active recovery (if you’re not injured of course) even on the day after a race, and then basically do active recovery workouts until you feel that your aerobic system is back to normal.
I have also found that recovering after Ironman, it is important to keep up your activity or else you fall back in fitness level. Of course, you cannot maintain pre-Ironman levels of intensity and duration. But it is important to do some speed work to keep your muscles primed for that kind of activity. After Ironman Brazil this year, I took my first week and dis active recovery until my muscle soreness went away. Then I started doing some faster speed work, but not fast track workouts or sprinting on the bike or swim. Basically I would get my speed up but cut back on the duration. Whereas previously I could do 2, 3, 4 or higher minute intervals, I would only do 30 seconds per interval and do at least a minute jog or walk recovery. The overall workout I would cap at 30 minutes. By keeping my muscles neuromuscularly stressed but not overstress my muscles and aerobic system, I found that I could gain benefits in active recovery and prevent my body from falling into fitness levels that approached the way I was right after the winter off-season.
In previous years when my Ironman recovery stretched to 4-6 weeks, I had often done almost nothing during those days, following the advice of some books. But as I waited for my aerobic system and body to come back, I found that it was really tough to get back into the racing groove. My body had regressed back to a pre-Build phase state! Definitely not good, if you have races after Ironman!
What other things help my recovery? I eat immediately after the workout, even before taking a bath. Lately I have taken to eating half a cake of tofu and a bowl of rice to replenish my fuel stores after my long swim and ride on Saturdays. This is in addition to drinking down a glass of Endurox, into which I also dump a scoop of Endurolyte powder for electrolyte recovery and a packet of Emergen-C to bolster my immune system. Remember, everything gets stressed after a long workout, and you need to make sure you replenish whatever your body has used up during its long hard effort.
Ice baths are also key in my recovery scheme. More on that in this post, Call Me Mr. Freeze.
I also discovered a supplement which seems to be working really well. It’s called Sportlegs and it seems to nearly completely remove the burn in my legs both during workout and also afterwards. Their claim is that these lactate compounds of common vitamins raise the blood lactate level and tells the body not to make so much lactic acid which is the cause of “burn” in your muscles. I take 3 pills before my long workouts. Then I take 3 more post-workout. During a race, I’ll take 3 before racing, and then 3 every three hours during the race, and of course 3 after the race.
One other word about recovery. I have found that recovery varies by where you are in the race season. For me, as I cross into the second half of my race season, my body has experienced tremendous stress and now I only swim and run twice a week, with sometimes recovery runs and swims earlier in the week coming off the long swim/ride/run Saturdays. But yet, I do not experience a slowdown; I maintain my speed. It only goes to show that you don’t have to train intensely each sport 3-4x a week. You need to listen to your body and give it the proper rest it needs.
The essential message is that you shouldn’t blindly follow training programs. You need to be acutely aware of what your body needs and adjust your training program accordingly. Hammering your body through intense workouts week after week, month after month, could wear on your body over time. Some people can take it, but some cannot. If you’re like me, you need to reduce the number of workouts but not the quality, or else you risk injury. You need to do what your body needs and not stress about following a training program or missing workouts. As a guide, I make sure I do my long bike, swim, and run each week. During the week, I often only do one more intense workout and then the other workout is an active recovery workout.

The books say that you should run off the bike but often it’s only towards the end of the training cycle, right before taper as you peak. Coaches will get you to run after a long bike, but they tend to tell you that a bit of jogging is all you need.
The books also say that you should take it easy until your body recovers from biking legs and switches to running legs, and to be patient about it. So thus you should not worry if you’re just jogging the first mile or so.
These do work somewhat, but I don’t think it’s enough.
In my own experience, I take about 10 minutes to get my running legs back. And naturally, the shorter the course, the better. But running a little bit off the bike during training wasn’t enough to get me speed during the run. At Ironman Brazil, it took me almost a full 30 minutes to get some of my running legs back. It was way too long a time.
In the last 3 Ironmans, I have consistently ran about a 4:51 marathon. But yet my marathon PR was 3:51. I think I should be able to run a 4:30 marathon but yet I cannot. Something else was needed.
I started asking my fast triathlon buddies on how they train for running off the bike. Their comment was that this kind of training can only be done AFTER you’ve put your body in a depleted state. You can’t train by not being tired. The body needs to adapt to switching from biking legs to running legs while super tired. So they go out and ride 80-120 miles and then run as fast as they can for about 3 miles afterwards, just simply to get their neuromuscular systems adapted to moving their legs in a running fashion after a long bike. They also practice getting up to pace as soon as possible after transition, instead of just jogging the first mile or so, waiting for their legs to come back.
Two things going on here:
1. You need to get your neuromuscular systems to switch from biking to running as soon as possible.
2. Research has shown that your best running times are achieved by running faster than you think early on, versus holding back and then running faster later. Almost everyone slows down near the end, and negative splitting makes it harder for you to make up lost time from the early portion of the run. So inevitably, if you start out faster, you’ll have a better time as long as you don’t flame out later but maintain as hard as pace you can as your resources dwindle. So you better go out faster sooner if you want to get a better time.
I started biking long and then running like hell after the bike. I started with a 10 minute run and gradually increased that to a 20 minute run and inserted hills into my run path. How funny was this.
The first time I went out my legs felt like bricks and really floppy. I basically just tried to move my legs as fast as possible and it was really tough. They did not want to move like that at all. I felt like I was pounding the pavement and didn’t have much form at all.
The second and third times got progressively better. As soon as I went out, it was hugely uncomfortable and my legs felt like big floppy duck feet. But according to my GPS, I was doing 7:30-9:00 minute miles. Much better! And I was maintaining strength up and down hills as well.
The fourth time I went out, my legs didn’t feel like bricks but definitely very floppy. Now I was definitely maintaining 7:00-8:30 minute miles but my HR was jumping to LT very fast and I had to walk a bit. My body was adapting to the stress and now my next step is to determine pacing so I don’t flame out.
Like many things, this training was taking time and was HUGELY uncomfortable, but thankfully with no pain. You gotta put up with some discomfort and over the next few weeks you’ll see results. I hope to draw out my after-bike run up to 30 minutes with some hour long runs inserted.
