At least I'm not the only one to have trouble with the heat and humidity today. It was a very short after work ride. I'm waiting for motion-based to tell me what the temps and humidity were, but it was in the 90s and humid.

I stopped 3 times to lay down in the shade as I thought I was going to get sick. I finally pulled into a friend's house, walked right in to the frig, got a Gatorade, and sat in the kitchen floor and drank it. She was in the bathtub. Her BF came in and found me sitting there and got me another Gatorade. I drank that one too.

I just haven't been riding enough, plus it hasn't been hot enough, for me to be acclimated.
