A century ride is a bicycle ride of 100 miles (160.9 km) or more within 12 hours, usually as a cycling club-sponsored event. Many cycling clubs sponsor an annual century ride as both a social event for cyclists and as a fund-raiser for the club’s other activities. A sanctioned century ride is organized and conducted under the rules and liability protection of a sanctioning organization, such as the League of American Bicyclists. Sanctioned rides typically have rest stops every 25 miles or so, where water, food and toilets are available for cyclists. On a supported century ride, the route is patrolled by a sag wagon to assist riders with bicycle maintenance, or provide transportation back to the starting line for those unable to ride the entire course.
