bus
n.— «Thami would have insisted on being co-driver or at least conductor of our bus. A bus, in running parlance, is a group of like-minded runners aiming for the same finishing time, who run together to share drinks, information and encouragement.» —“The true meaning of the Comrades” by Bruce Fordyce Mail & Guardian (South Africa) June 15, 2007.
