Known for its 5,656 acres of pristine fields, woodlands and natural beauty, Fair Hill Natural Resources Management Area was a picture-perfect spot to host our 20-mile premiere in 2023. MammothMarch returns to the Delaware Valley on June 15, 2024.

Bordered by Pennsylvania to the north and less than half a mile west of Delaware, Fair Hill was previously owned by William duPont, Jr., an avid equestrian rider who acquired the farmland to enjoy riding as well as fox chasing. Once one of the largest private land holdings in the east, Fair Hill is now all yours to conquer!
