A cyclist who does long-distance endurance riding with no outside support, typically not for competition but to complete the course within a certain time limit. According to Randonneurs USA "friendly camaraderie, not competition, is the hallmark of randonneuring." Randonneuring goes back to the beginnings of cycling. The most famous event is Paris-Brest-Paris, a 746-mile test that has to be completed within 90 hours. Begun in 1891, it is still held every four years in August.
