 Stopping and starting is especially difficult, and both riders really need to be in sync, which is not easy. For my training, I was paired up with Kate Perkins, another sighted rider. Oh, jeez. No, no, it was kind of a hard stop. Perkins and I joked it was a little like learning to ride a bike again. When you're on the front of the bike, you realize the tremendous responsibility you have for the safety of the person on the back.
