The Marji Gesick 50/100 is one of the best long-distance endurance mountain bike races in the United States, is part of the National Ultra Endurance Series (NUE) and takes place in the Upper Peninsula of Michigan. This is the tip of the spear when it comes to difficulty - established in 2015 in Ishpeming, MI; this is more than just a race; it’s an expedition into the soul, a journey to discover the extremes of human endurance. The race sells out quickly every year, a nod to the event's popularity.
The Marji Gesick is a product of the 906 Adventure Team and is one of the planet's hardest and most grueling one-day endurance mountain bike races and one that the team at Strambecco considered to be one of the Best Mountain Bike Race Events in the Midwest and one of the Best Cycling Race Events in Michigan. This is not a straightforward 100-miler but obliterates the mountain bike endurance race calendar competition for having a technical single track and a sickening amount of climbing. A great quote from a great mountain biker named Mike Webb goes like this: "I've done some hard stuff. Leadville 100, Maah Daah Hey 100, La Ruta de Los Conquistadores, Lumberjack 100, Butte 100; Hands down, Marji Gesick is the most terrible of them all."
Event & Course Info
There are three biking events every year at Marji Gesick 50/100, and every 5 years, a 4th colossal 200-mile event. Courses aren't shared with participants until the week of the event but know that you will be cycling on treacherous trails, challenging your limits, all while navigating through unpredictable weather conditions and formidable terrain. Beyond its brutal route and testing climate, what truly sets Marji Gesick apart is its philosophy. It doesn't merely challenge the physical prowess of the participants but grills their mental strength and perseverance. The lack of aid stations amplifies the event’s exclusivity, urging participants to be their own saviors, equipped with the right gear and a strategic plan.
The unique LeMans start, where participants of the 100-mile bike and duathlon begin with a half-mile run, and the LeBike, a reverse version requiring riders to bike half a mile to their run, adds another layer of challenge. Moreover, there are tokens to collect at checkpoints, and the race boasts some of the most challenging terrains, from rugged singletrack to relentless wilderness, participants are exposed to paths that seem uphill from the start to finish.
The organizers, 906AT productions, have crafted an event where every participant is a lone wolf. With an emphasis on self-reliance, the message is clear: you're truly on your own.
Here is a rundown of each event:
MG100BIKE: A grueling 100-mile bike journey beginning at 7:30 am on Saturday. This also includes the "Worst of Both Worlds." There is a 12-hour cutoff and 22 hours for the Duathlon.
MG50BIKE: A 50-mile bike race setting off at 8:00 am on Saturday.
MINI-MARJI: A shorter version for those seeking a taste, starts at 10:00 am on Saturday.
MG200: The colossal 200-mile race (held every 5 years)
There are also two running events that take place that weekend, the MG50 & MG100RUN.
While every participant who braves through is a winner, the ones completing the 100-mile race within 12 hours earn the coveted buckle. For the ultimate biking aficionados, the Triple Crown Endurance Trilogy awaits. Completing three of the most challenging events, including Marji Gesick 50/100, The Crusher, and The Polar Roll, will earn you a lifetime entry into the Hall of Pain.

The Marji Gesick 50/100 doesn't just stand out because of its unparalleled challenges. It's impeccably organized, promising ample amenities over the weekend, right from training plans to training camps.
