Randonneuring: Randonneuring is long-distance unsupported endurance biking. This type of driving is non-competitive in nature, and self-sufficiency is paramount. When riders take part in randonneuring occasions, they’re a part of a protracted custom that goes again to the start of the game of biking in France and Italy. Pleasant camaraderie, not competitors, is the hallmark of randonneuring.
