Marji Gesick - Marquette County, Michigan
Marji Gesick is an endurance mountain-bike and trail event produced by the 906 Adventure Team, a Marquette County 501(c)(3). The event series for 2026 includes Marji Camp (June 4–7) and Marji Gesick race weekend (September 18–20). The production began in 2015 and was designed to link major trailheads across Marquette County.
Available event formats include:

- MG50 bike and run
- MG100 bike and run
- Worst of Both Worlds (duathlon)

The event follows a self-supported ethos. Organizers do not operate aid stations; GPS navigation is mandatory. Participants are responsible for their own food, gear, and on-course decisions. E-bikes are not permitted. Drop bags are collected at the start and transported to Jackson Park (199 Tobin St, Negaunee, MI 49866); Jackson Park is on course for defined mileage markers. Checkpoints use tokens at undisclosed locations; losing a checkpoint item can result in disqualification.
Marji Camp at Rippling River campground pairs participants with coaches for two- to three-hour local rides, optional night rides, shared campsites, and group activities to prepare riders for the main events.
A portion of entry fees is returned to local trail organizations. The production emphasizes independent navigation, recommended gear lists, and preparedness for variable terrain and weather. Visit the organization's website for the most recent information.
