Randonneuring is a long-distance cycling sport where participants ride predetermined routes, typically ranging from 200 to 1,200 kilometers. Riders must complete the course within a set time limit, often facing various terrains and weather conditions. The focus is on endurance and self-sufficiency, as cyclists navigate without support teams. Events are organized as brevet rides, where cyclists receive a card to document their progress at checkpoints. Successful completion earns riders a certificate and recognition within the randonneuring community. This sport emphasizes camaraderie, adventure, and personal achievement, attracting cyclists of all skill levels.
