Nice cool weather. Uncomfortable until about the second mile in, then perFECT!
My coworker and I paced a casual group for a bit. The handcycle in that group was low, low, LOW to the ground. It was clearly meant for competition and clearly was used that way (he had paper numbers still taped to it). That pacing ended when my coworker's chain came off ... of a single speed.
Despite that, a very nice ride.
