Big A 50K Trail Race

This year’s race will take place on Saturday, May 4th with the traditional 7:30 AM start.

Registration through RunSignUp opens February 1 at 5:00 AM.

The Big A 50K 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. The full 50K has 5,787 feet of elevation gain. Footing is technical with plenty of rocks, roots, and elevation changes. Trail running shoes are recommended. All runners should train for and plan to finish within 10 hours.
