ENDracing is a grassroots organization that puts on the toughest races in North Dakota. We are a small group of part-time race directors and volunteers who have been bringing more adventure to one of the flattest places on Earth since 2009. Our races include the longest open-water swim race in North America (END-WET), and offroad Ironman-distance triathlon, a late-winter ultramarathon, back-to-back 12-hour mountain biking and trail running races, and several shorter events.
