Welcome to Marquette County.

The Upper Peninsula is a vast landscape that quickly overwhelms the unprepared. Da Marji, as referred to by locals, will fool you. Do your homework. Believe the stories. Prepare. Marquette County trails are littered with rocks, roots, and punchy climb after punchy climb hammering you into submission. Since 2015 our average DNF rate is 60%. Weather in the U.P. can be defined as unpredictable. We encourage you to prepare for everything from the possibility of all-day rain or even flurries. Not kidding.

The coveted Marji Gesick belt buckle is awarded to those that can complete the 100-mile course in under 12 hours. Many have tried. Almost all have failed. They usually return to complete their unfinished business.
