Welcome to the Black Bear Trail Races, hosted by White Mountain Endurance in scenic Waterville Valley, NH!
Join us for an unforgettable trail running experience with events for every level. Test your limits on Saturday with our demanding 50K Ultra Trail, a formidable journey boasting 7,700 feet of elevation gain around iconic 4,000-foot peaks, or choose the classic 23 kilometer course through the oldest maintained trail network in the US.
We also offer a beautiful 4-mile tour of White Mountain forests and streams with no road, and a delightful 1-mile Bear Cub Fun Run for the whole family! All race distances promise stunning views, finisher's medals, post-race snacks, and the spirit of mountain running.
