Yeah, that's too hot.
The race kicked my ass. I never realized how much being post-menopausal screws with the body's temperature regulation system. It was 85 or so and we were riding a lot of exposed areas and I truly thought I had heat exhaustion a few times. My heart rate was a good 10 BPM higher than normal for this particular ride (I rode it early Thursday morning and felt great.) I had goosebumps at times. I literally don't know how I finished. The race looped twice so I came to the base area after 8 miles and almost didn't go out for the final lap, but decided I wasn't quitting so went back out. I did set a few PRs on the descents (gotta loved closed trails!) But my climbs were abysmal.
