It was a near 110 today and it's still 85 out at 11:30 pm. I couldn't get up early this morning and couldn't get myself to go ride in the blazing heat. I usually freeze my bottles overnight and they stay cold for about an hour and a half if I leave my house early enough. The only advice I have is wear a lot of white and hydrate often. I also take my helmet off on climbs if the road is pretty low traffic.
