In an endurance ride, discussed in this article, the winning horse is the first one to cross the finish line while stopping periodically to pass a veterinary check that deems the animal in good health and fit to continue. In the United States, most endurance rides are either 50 or 100 miles (160 km) long.dditional awards are usually given to the best-conditioned horses who finish in the top 10 for distances of 50 miles (80 km) or more. The Best Conditioned, or BC award is generally more prized than finishing first, as it is determined by a combination of speed, weight carried, and veterinary scores.
