A 24-hour, 100-mile horse ride from Lake Tahoe to Auburn, California, the Tevis Cup was first held in 1955. The important thing to know about this race is found on the Tevis Cup FAQ: "The weather conditions from year to year are mostly the same: HOT and DUSTY." One of the major difficulties here is not just getting your horse to the finish line, but making sure your horse is still "fit to continue" when it reaches the finish line. If you do so, no matter what place you come in, you get a silver belt buckle. That's right: 100 miles in 24 hours. For a belt buckle.
