Mammoth March Delaware Valley

MammothMarch Delaware Valley is back!

Happy New Year!

Let’s work toward a Mammoth goal together!

Individuals are responsible for their own registration, travel, and lodging. Howeverer, I plan to create a training schedule to get us prepared. I will be posting hikes at Boyce and Duff parks in the coming weeks.

MammothMarch returns to northeast Maryland! After yet another sold out edition in 2024, we will be back for a third MammothMarch Delaware Valley on May 31, 2025.

Once one of the largest private land holdings in the east, Fair Hill – known for its 5,656 acres of pristine fields, woodlands and natural beauty – is once again all yours to conquer.

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. Today, it’s a picture-perfect spot for one of our most popular 20-mile hikes.

Master the challenge and spend a beautiful and challenging day hiking 20 miles at a stretch. Getting your finisher medal, you will be exhausted, but proud and happy... as well as part of our amazing community of nature-lovers, hikers and MammothMarch addicts!
