Skijoring is a primarily Scandanavian sport, in which a person on skis is towed by dogs or horses, or sometimes by a snowmobile. It was held several times at the Nordic Games (1901, 1905, 1909), which were the early forerunners of the Winter Olympics. In 1928 at St. Moritz the sport was contested as a demonstration event with the skiers towed by horses. It was held on a frozen lake, with seven competitors starting in a mass start race. Little else is known of the event and it was never contested again at the Winter Olympics as a demonstration sport.
