The AERC, or American Endurance Ride Conference, is an organization dedicated to promoting and regulating endurance riding in the United States. Founded in 1972, it sets standards for competitions, provides educational resources, and fosters a community for riders and horses. The AERC also maintains a national database to track ride results and horse performance. Endurance riding is a long-distance equestrian sport that tests the stamina of both horse and rider. Rides can range from 25 to 100 miles, and participants must navigate various terrains while ensuring the health and safety of their horses. The AERC plays a crucial role in ensuring these events are conducted fairly and safely.
