Marji Gesick

Marji Gesick is an endurance mountain bike and trail event produced by the 906 Adventure Team, a 501(c)(3) nonprofit based in Marquette County. The main event weekend for 2026 is scheduled for September 18–20, 2026. A preparatory Marji Camp is scheduled June 4–7, 2026 at Rippling River campground in Marquette where participants are paired with coaches for guided rides and optional night rides.

Event formats include multiple distances and formats:

  • MG15
  • MG50
  • MG100
  • MG200 (held once every five years)
  • Worst of Both Worlds
  • Mini-Marji

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. Visit the organization's website for the most recent information.
