Great point. Hadn't thought of that. I think early mornings are sometimes harder (for me, anyway) because it's harder to be hydrated after sleeping 8 hours than if you're anticipating a 6 p.m. ride by drinking a little more throughout the day. It also was distinctly more humid this a.m. than last p.m. Or at least I certainly sweated more.
