The documentary covers the 1982 Western States 100-Mile Endurance Race, commonly known as the Tevis Cup. Riders have 24 hours to finish the race, which goes from the Robie Equestrian Park near Truckee, California to the Placer County Fairgrounds in Auburn, Ca. The documentary was voiced by Hoyt Axton. There was a second documentary about the 1983 race.—redgundogs
