Marji Gesick

Marji Gesick is an endurance mountain bike and trail event produced by the 906 Adventure Team, a registered 501(c)(3) nonprofit based in Marquette County, Michigan. The event weekend for 2026 is scheduled for September 18 to 20. Marji Camp is scheduled for June 4 to 7, 2026. The event began in 2015 and was originally designed as a 100 mile route connecting major trailheads.

Distances and formats include:

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

The event follows a self supported ethos. The organizer does not operate aid stations and advises entrants to carry navigation and survival gear. GPS is mandatory. E bikes are not permitted. Drop bags are accepted at the race start and are moved to Jackson Park at 199 Tobin St, Negaunee, MI 49866; those drop bags appear on course at roughly miles 65 and 85 for 100 mile events and roughly miles 15 and 35 for 50 mile events. Checkpoints are at undisclosed locations and collect tokens; losing a checkpoint item may result in disqualification.

A portion of entry fees is returned to local trail organizations including NTN, RAMBA, Munising Bay Trails Network, and Friends of Harlow. Official timing is provided by Superior Timing. Visit the organization's website for the most recent information.
