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.

Join us Saturday, September 19th for the Mt A Trail Challenge!

We're excited to have you join us at the summit of Mount Agamenticus for the 10th Annual Mt. A Trail Challenge!

The 5K begins at 9 AM and the 1 Mile starts at 9:20 AM.

Run, hike, roll or stroll through either our 1 Mile or 5K course. This challenge is timed the good ol’ fashioned way with stop watches, thanks to our local York Highschool Cross Country Team. There are no traditional age category prizes, but there will be a raffle for all participants!

As always, all funds raised go right back into Mount A conservation & education efforts. Thank you for your continued support!

This year, any previous participants who beat their own personal Trail Challenge record can receive a Mount Agamenticus Conservation Region logo pin!
