Complimentary parking is available on site.
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. MammothMarch Hiking Passes will be made available for new participants, and returning participants may bring existing passes to collect 2027 stamps.
