Endurance riding is an equestrian sport in which horseback riders race long distances, usually 50 or 100 miles (80 or 160 km). To ensure the safety of the horses during the rides, veterinarians periodically inspect the animals and eliminate from competition any horse deemed unfit. Although any breed can compete, Arabian horses often dominate the top levels of the sport due to their natural speed and stamina. How long do winners usually take to cross the finish line in 100-mile (160-km) races?

Why did Ivan murder his son—and only viable heir—in 1581?
