How do you deal with the heat?

[Tri Girl]

I never acclimate to the heat. I grew up in SW Arizona, so you'd think I could handle it, but I cannot. Not the humidity anyway. We have temps in the 100's with humidity in the 60-80 range all summer long and it just kills me. I've tried it all- cool wings, neck coolers, pouring water on me regularly, etc. I get heat headaches that debilitate me for a day after long workouts in the heat, and last year I started developing heat rash on my thighs after long rides.
This year I have resigned to not struggle through it.
I run at 4 am (when I have to do long runs of 15+ miles) so I can finish by 7 or 8 am. I started riding my mtn bike again so I can ride in the trees and the shade. I haven't ridden my tri bike in I don't know how long because I just don't want to deal with the heat and the sun. There are no shady rides in this part of the country.

I do LOVE ice in the bra, tho. In fact, lately I've been putting one of those very small gel packs in the freezer and sticking that in my bra for long runs. Talk about keeping you cool!
