Good question. I did my first Olympic-length tri last weekend, and I was totally unprepared for the heat of the run. I train by running every morning at 6:00 or 6:30 (depending on how long the run that day), when the average temperature is about 40 degrees where I run. On triathlon day, the run was in 70-degree weather. Ouch!

I might add that, because of the heat and because I hadn't done much brick training my pace on the 10K run (which was on dirt trails through hilly/mountainous terrain), a averaged 10 min/mile. By comparison, I recently did a 10K race, in the cool of the winter and without the "benefit" of having "warmed up" with a swim and a ride, at a 7:07 pace. (I'm 58 years old.)

So, the short answer, train as close to race conditions as possible.

Do as I say, not as I do. I've got the Utah Half IM coming up in a week; the half-marathon run will be during the heat of the day, and I've yet to do one training run in the heat. My goal, obviously, is to just finish.

Good luck with your IM training!

I try to train as close to race conditions as possible. I used to run in the morning but I found during my races, running in the heat of the day, my body wasn't conditioned for it. So now I try to run in the afternoons.

Good Luck
