Ishpeming, United States • 18-20 Sep 2026

Marji Gesick : Marquette County, Michigan

Marji Gesick is an annual endurance mountain bike and trail event produced by the 906 Adventure Team, a registered 501(c)(3). The event weekend in 2026 runs September 18–20 and includes a preparatory Marji Camp in early June. Routes use local trail networks across Marquette County and connect major trailheads.

Event formats include multiple distances and formats:

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

The production follows a self-supported ethos: the race does not operate aid stations, the course is not signed, and GPS navigation is mandatory. E-bikes are not permitted. Participants may leave drop bags at the race start for transport to Jackson Park (199 Tobin St, Negaunee, MI 49866); out-and-back racers may leave a drop bag at Forestville for the following morning. The organizer publishes recommended gear lists covering lights, backup batteries, tools, hydration, and clothing.

Marji Camp is held at Rippling River campground; participants are paired with coaches for local rides and optional night rides, and community activities take place around campsites and campfire talks. A portion of entry fees is returned to local trail-building organizations. Local bike shops and supporting partners are listed as community resources for participants.
