MammothMarch Delaware Valley 2027

MammothMarch Delaware Valley takes place at Fair Hill Natural Resources Management Area in northeast Maryland on May 22, 2027. Fair Hill covers about 5,656 acres of fields, woodlands and creeks and is the setting for a single-circuit loop of scenic trails.

Participants cover 20 miles, a route that typically takes about eight hours to complete. The course has around 1,600 ft of total elevation gain and runs mainly on unpaved hiking trails, dirt trails, gravel roads and forest floor.

Aid and refreshment stations are positioned roughly every 5 to 7 miles and provide toilets, food and drinks; those supplies are included with registration. There are cut-off times at aid stations for safety. On-site parking is complimentary. Final route details will be published about two weeks before the event, and lodging information will be provided later.

All finishers receive a personalized certificate and a finisher medal; participants who do not complete the full distance receive a certificate stating the mileage covered. A MammothMarch Hiking Pass will be available for new participants, and returning participants are asked to bring existing passes to collect 2027 stamps. Merchandise ordered through the event store is available for pickup on event day while items from the official online shop may be shipped.
