Triathlon at Retirement

I always feel a lot of pressure at the Kerrville triathlon which is in my hometown. This year, I placed 2nd in the W60-64 division, quarter ironman distance (1100 yards swim, 29 miles bike and 10.4 miles run). The competitions are very well organized and set in a beautiful environment, but I have difficulty enjoying it.   On Friday afternoon, I volunteered at the sprint bike check-in for 5 hours, and it was hot, over 90f (32C). I already knew from my experience last year, that to avoid overheating on the run was the main challenge. I have spent most of the summer in much cooler temperatures in Sweden, and only about 3 weeks in Texas heat, so I worried that I was not fully acclimatized.  I prepared as much as I could, I did several bike and run workouts in the midday heat the weeks before the competition. On the morning of the event, I brought a small cooler full of ice and a water bottle to transition 2.  The Guadalupe River where swimming was taking place, was too h...

Below is a comparison of my times on a 3.1 miles flat run course, and a 2.8 miles hilly run course. I also show temperature and heart rate.

On many occasions during warmer weather, I think I have done really well, I pushed harder than normal, and the feeling of exertion is almost unbearable. Then I see the time, not good and I am disappointed. Thinking back, it has been a pattern my entire life, winter training is going really well, I am doing good times, but when temperatures rise, performance drops like a...
