Talking to the local State Department of Roads Supervisor, he told me about a Canadian cycler who was found on the road unconcious last Friday by a DOR employee. I guess the guy was laying on the side of the road, still clipped to his bike. The DOR guy had some water, and started cooling the biker down, and then a farmer stopped, and they put the fellow in the air conditioned pickup. The rider recovered, and continued on his trip. The temperature was in the lower 100's, and he was working a lot of hills.
Today, with a temp of 103 and humidity of 60+%, it would be easy to get into trouble. I only rode 7 miles, and maintained an easy spin, and consumed an entire oversized bottle of water!
Lets all be careful out there! Don't let the heat get you!!
