Even for me! I rode my bike 13 miles today under the scorching July sun. I normally like a little heat, but today was too much. It was 97 degrees and there was a wind that felt like the breath of Satan. I cut the ride short because my water was making me nauseous and I was beginning to feel light-headed. If I don't get out before 9:00 AM, I will have to wait until evening. Night riding is fun, but dangerous. In addition, the bugs are attracted to my headlight. Ew!
