I also am looking at those temperatures with trepidation. It's a bad combination for me, with no gradual ramp up. It was cloudy yesterday, and even felt cool when we were in the shade. But Friday's ride was sunny and hot, at the same temperature. I always say that 23 years living in hot climates where you are always inside, in AC, did me in for heat acclimation.
It was supposed to rain today, but it is mostly staying south of here. I need to rest, but a short walk/hike on the trail might be in order. A bit nervous about Thursday, when it is forecasted to be 85 and we lead a ride that starts at 6 PM. Obviously, the sun is going down by this time, but ugh! And, I hope Wednesday's group ride is in a shady spot, as I am planning to go.
