2 years ago, I collapsed after a 10 mile running race, they said I had heat exhaustion. It took me over a month to recover, every time I would try to train I would start seeing stars and get really dizzy. It finally went away and I was able to complete an Olympic distance tri 2 months later, but not the best time ever. I have noticed since, that I do not do well in the heat. Yesterday my fiance and I went riding at 11:30a and it was in the low 90's with high hummidity, all was fine until we tried climbing this 2 mile long hill. I had to stop because I felt sick and started hyperventilating. I slowed my breathing down by sitting down on the side of the road. My fiance pured cold water on my neck and head to cool me off. After a few minutes I felt better, still a little dizzy and felt sick to my stomach, but well enough to get back on the bike and go back down the hill. We road on flat roads for awhile and did ok. However, I noticed when we stopped (we had to wait for geese to cross the road) I started to feel dizzy and sick again. We decided to head back to the truck and go home. After a stop at the local market for a sandwhich, I felt much better.
So here is my questions, what happened? Can my body just not handle the heat? I am thinking about doing IMKY (I live here) next year, but not sure how an end of Aug. race with 90* temps and hummidity would go over. If it is all heat related, can I train my body to get used to it? If so any suggestions?
Thanks to all!
