RegisterTrivium Racing has been dreaming of producing this epic event for years, and we’re thrilled to finally unveil our exciting new race plan. This event will feature a 100-Mile, 100-Kilometer, and 50-Kilometer Ultra, as well as a relay option for the 100-Mile. The highlight of this course will be crossing the top of Michigan's lower peninsula from Lake Michigan to Lake Huron. The 100-Mile course will be point-to-point, beginning in Petoskey and concluding in Alpena. The 100k course will also be a point to point race finishing in Alpena. Our 50K race will feature an out and back course from Alpena that will have very manageable cutoffs and great running surfaces! Athletes will navigate a variety of terrain, including single-track trails, gravel roads, limestone paths, and seasonal roads. While no 100-mile race is ever easy (and we know you wouldn’t want it to be), our goal is to make this event as approachable as possible for first-timers while still delivering a rewarding experience for seasoned vets. Special awards will be given to those finishing the 100-mile race in under 24 hours, and we’ll also have a generous cutoff time to encourage more participants to tackle this incredible course. You can expect frequent, well-stocked aid stations approximately every 5 to 8 miles to keep you fueled and supported throughout the race.
