“Randonneuring is long-distance unsupported endurance cycling. This style of riding is non-competitive in nature, and self-sufficiency is paramount. Participation in randonneuring events is part of a long tradition that goes back to the beginning of the sport of cycling in France and Italy. Friendly camaraderie and perseverance are the hallmarks of randonneuring. 
Randonneur Events
The most common type of event is a brevet (pronounced breh-VAY), referring to the certificate (brevet) the participant receives signifying completion of a particular distance. Randonneur events are 200 km, 300 km, 400 km, 600 km, 1000 km, and 1200 km. The longer events are held over multiple days. Along the course, you check in at various places to show that you completed the entire course. During longer events, sleep breaks are planned at intermediate points. In the end, you get a medal if you complete the course within the generous time limit. If you like going fast, there usually is a group who try to see how quickly they can complete the course. But the results are listed alphabetically, and everybody gets the same medal, so it is not a race. Our long rides are challenging for anybody, but every finisher is a winner.”
