Does Nordic skiing seem like too much work? Instead, try skijoring—or being towed on skis by a horse, dog or maybe even a car. Skijoring with dogs is the most common form of the sport, and it can be a fun way to play outside with your pet. There are several equestrian skijoring events held across the Western U.S., including the World Skijoring Championships, held in Whitefish, Montana, and a yearly event in Leadville, Colorado, where competitors have to race over jumps.
