The event follows a self-supported ethos: the organizer does not operate aid stations and participants must be prepared to navigate and resupply independently. GPS navigation is mandatory and checkpoints are at undisclosed locations where tokens are collected. Drop bags are collected at the start and moved to Jackson Park, 199 Tobin St, Negaunee, MI 49866. E-bikes are not allowed. Timing is provided by Superior Timing.
Logistics and rules include transfer of registration and race changes allowed until August 1, no refunds, and specific buckle cut-off durations for certain events. A portion of entry fees is returned to local trail organizations. The event materials include recommended gear lists and published routes in the week of the event.
