Big A 50K Trail Race (50K) - May 2, 2026 | York, ME

Embark on an unforgettable trail running adventure at the Big A 50K Trail Race on Saturday, May 2, 2026, in scenic York, Maine. This challenging 50K ultra features a distinctive course comprised of three exhilarating 10.35-mile loops, commencing and concluding at the breathtaking summit of Mount Agamenticus, affectionately known as "Big A." Runners can anticipate typical race day conditions with highs around 63°F and lows around 40°F, accompanied by a modest 16% chance of precipitation.

The Big A 50K course is renowned for its technical terrain, navigating mostly single track with sections of dirt roads and ATV-type trails. Prepare for plenty of rocks, roots, and continuous elevation changes across the loops, including ascents over Second Hill and Third Hill, culminating in a total elevation gain of approximately 5,787 feet for the full 50K distance. Trail running shoes are highly recommended to tackle the demanding footing, while the stunning natural scenery and panoramic 360-degree views from the summit of Mount Agamenticus offer a rewarding backdrop to your effort.

Beyond the physical test, the Big A 50K offers a unique, grassroots ultra experience with a fantastic family-like atmosphere among organizers, runners, and volunteers. Rather than a traditional registration fee, participation is secured through a minimum $20 donation, directly supporting the Mount Agamenticus Conservation Region's trail construction and maintenance. Runners contribute to the communal spirit by bringing items for the aid stations, which are primarily located at the start/finish, and a side dish for the festive post-race cookout, complete with grilled food, snacks, and drinks, all enjoyed with fellow trail enthusiasts and spectacular views. For those seeking a significant challenge but not the full 50K, there are opportunities to cross the finish line after approximately 10 or 13 miles.
