Congrats on your ride today!!! We, too, have been battling 100+'s for a week now and this coming week looks no different (I'm from AZ and thought I'd left it behind when I moved here- but I guess not ). You're right- it's just too darned hot to ride when it's that hot. I'm super proud of you for making it 21. I'll bet those slick tires made a world of difference!!!

Can you ride early, early morning /dawn before the sun comes up before going to work? I feel your pain, but hang in there. In a couple months when it cools down a bit, you'll be throwing down 40 mile rides with ease!!!
