I didn't ride Saturday, but yesterday we did a 22 mile loop that is newer for us. There was a guy waiting at a stoplight to cross the highway at about mile 5 , and we took off ahead of him, which was weird, since he looked like he had been cruising. Then, there was a hill and we lost him. After the next light, he caught up and passed us, so DH decided to draft him (he asked if it was OK). At this point, I could not go any faster . So, we cruised in behind him, at about 20. I noticed that the guy never, ever shifted, so I guess that's why he couldn't climb. We split from him, went for lunch at the end of the ride, and I ended up with an average much higher than normal.
