Last weekend I had a really fun 80-mile ride on the mountain bike. Unfortunately it wasn't all on dirt, but the parts that were dirt were great. At the half-way point I stopped in a bit of shade for some snack - an apple, some jerky, and an energy bar. The climbing was insanely hot. I don't know that I have ever sweat so much on my bike. By the end I drank 16 lbs of water. Luckily this spigot was flowing with nice, cool water. The sections of sweet flowing singletrack through the woods made it all worth it.
