Went for a nice ride today - 40 miles with 2,800' of elevation gain. It's a ride that I've been wanting to do for quite a while.

Right about when we get next to Calaveras Reservoir, my riding partner bonked. He started cramping really bad in his right hamstrings & quads, decided to walk for a few miles, but after a while, he just couldn't go any further. After walking for an hour and 15 minutes, he asked me to finish the ride, get the car, and pick him up (no mobile service until you get to the other side of the hills). 30 minute ride home, 15 minute drive back.
