“The hardest single-day mountain bike event in the country.” – Jeremiah Bishop, 2017 Marji Gesick 100 Winner, Canyon Topeak Factory Racing. 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. In 2017 our DNF rate ran near 70% as unseasonably hot September weather melted the field. Weather in the U.P. can be defined as unpredictable. We encourage you to prepare for everything from a repeat of last year to the possibility of all-day rain or even flurries. Not kidding.
