Living in Kansas and working in a non-air conditioned environment, I find that when I get home I just don't want to go out and ride when the temp is still hovering around the century mark. I am still able to get in some good mileage on the weekends when I can get out just after dawn and ride before it gets hot. My evening rides however, are getting fewer and fewer lately. Fortunately I am able to get to the gym in the evenings and get some strength and weight training.
How are you handling the hot temperatures this summer? Has it affected your mileage from back in May and June?
Fortunately Friday, Saturday and Sunday are all days off for me this weekend and I can RIDE.
