About the Event

The Big A 50K Course

The course is composed of three 10.35 mile loops starting at the summit of Mount Agamenticus (Big A) and climbing back up the Big A and going over Second Hill and Third Hill and back up the Big A. There are opportunities to cross the finish line at approximately 10 miles and 13 miles (or any multiple of them up to 31 miles/50K). The terrain is mostly single track with some dirt road and ATV-type trails. Footing is technical with plenty of rocks, roots, and elevation changes. Trail running shoes are recommended. The full 50K has approximately 5,787 feet of elevation gain.
