Marji Gesick

Marji Gesick

Marji Gesick is a multi-distance mountain bike event produced by the 906 Adventure Team, a registered 501(c)(3). The event is associated with Marji Camp, a weekend of coached local rides, shared campsites, optional night rides, and group activities held at Rippling River campground in Marquette County in early June 2026. The main event weekend is scheduled for mid-September 2026.

The event follows a self supported ethos. Organizers do not operate aid stations and explicitly state that participants must navigate with GPS, carry recommended gear, and prepare for exposed, potentially dangerous terrain and variable weather. Checkpoints exist at undisclosed locations and collect tokens; loss of required checkpoint items results in disqualification. Drop bags can be left at the start line to be transported to Jackson Park in Negaunee for use on course.

Marji Gesick offers multiple race options and formats, including shorter and ultra distances, a duathlon variant, and occasional longer editions. The event returns a portion of entry fees to local trail organizations and lists local bike shops as community supporters. The race was established in 2015 and takes its name from local historical research; its organizers describe the event as a test of endurance and preparation rather than a supported race.

Notable operational details include mandatory GPS navigation, no e-bikes allowed, registration transfer and race-change deadlines in early August, and belt buckle time cutoffs for select results. Visit the organization's website for the most recent information.
