Challenge Yourself: Run, hike, roll or stroll through either our 1 Mile or 5K course starting at the summit of Mount Agamenticus. 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!
Volunteer: Looking to be involved day-of or leading up to the event? Volunteers are always needed! Please keep an eye on this page.
Donate or Sponsor: Businesses or organizations interested in sponsoring our 2026 event or donating prizes to the raffle can reach out directly to the Conservation Outreach and Education Coordinator.
Course Descriptions:
2025 5K Map: Starts in open field at summit, follows Big A trail around the top for a gentle warm up. Follow down the road to Hairpin Turn trail to the first water stop. Continues to Ring trail and follows it all the way around counter-clockwise, to second water stop before a challenging climb back to the top. Course will overlap slightly before the connection to Witch hazel trail. This year the course follows a portion of the Big A once again and finishes at the start area.
2025 1Mi Map: Starts at the center platform and follows the universal access trail around the inner loop and then outer perimeter to finish near our pollinator garden.
