The 50M race takes place on Saturday. It spans about 50 miles and has an elevation gain of approximately 5,520 feet. The course includes nine aid stations strategically placed to support runners throughout the race. The 50M race has a 15-hour time limit, and cutoff times are strictly enforced at various points along the route.

The 50K race also starts on Saturday and covers approximately 31 miles with an elevation gain of around 3,237 feet. Runners will navigate through moderate to difficult terrain, with challenging climbs up Sugarloaf, Top-of-the-World, Bareback, and Hogback peaks.

Both races fill up quickly, with registration opening each year on Black Friday at 8:00 AM EST. The 50K is capped at 350 runners, and the 50M at 175 runners. Given the event’s popularity, the 50K often reaches capacity within 1-2 hours of registration opening, so early signup is essential.
