This is my 50th fun filled summer in Tucson When it's over 100 degrees, it's too hot to ride or run. Period. I've been active outdoors ever since I was a tadpole and trust me - you don't acclimate to 100+ degrees. Desert animals know this. If I were to take a walk, it would be eerily quiet right now.

Once you get heatstroke, you can become extremely sensitive to heat. You did the exact right thing. So did your friends.
