⏵ Course guide · Michigan peninsula crossing
Wolverine State 100 crosses the width of Michigan's northern Lower Peninsula, point to point from Petoskey on Lake Michigan to Alpena on Lake Huron, over singletrack, gravel roads, limestone paths, and seasonal roads. I will walk you through the point-to-point structure and terrain first, then give you a pacing and fueling plan built around frequent aid rather than one defining climb, plus free tools to dial in your own numbers.
These facts come from the official Trivium Racing event page. Cutoffs, aid, and course logistics can change year to year, so confirm the current details before you register or run.
The 100M and 100K both run point-to-point across northern Michigan, beginning near Petoskey and finishing in Alpena. The 50K, run separately on Sunday, is an out-and-back based in Alpena with its own more approachable profile.
This is not a single-trail-system race. The route mixes serene singletrack, scenic seasonal roads, gravel roads, and limestone paths as it crosses the peninsula, so your effort and footing shift throughout the day rather than settling into one rhythm. Treat each surface change as a cue to reassess your pace, not just your mileage.
Aid stations arrive every 5 to 8 miles, fully stocked, which is generous spacing for a point-to-point 100. Use that frequency to your advantage: resupply predictably rather than overloading your pack for long, remote stretches the way some point-to-point 100s require.
The organizer explicitly frames this as a race for a first 100-mile finish, and offers special recognition for anyone who breaks 24 hours. Whether you are chasing that time or simply chasing the finish, the point-to-point crossing gives you a real sense of progress across the state that a looped course cannot replicate.
Without a single defining climb, the pacing challenge here is managing effort across genuinely different surfaces rather than managing one grade.
Singletrack, gravel, limestone paths, and seasonal roads each carry a different sustainable effort, even at similar grades. A grade-adjusted pace target helps, but stay mentally flexible: a pace that feels easy on limestone path may not be sustainable on technical singletrack later in the day.
Because the organizer has not published detailed cutoff splits, lean on a finish-time projection built from your own early splits to sanity-check your pace against the overall distance and daylight. On a point-to-point course, you cannot simply drop down or shortcut back to a central aid area if you fall behind, so build in margin early rather than discovering a deficit late.

Aid every 5 to 8 miles gives you a real advantage: build your fueling around consistent, predictable resupply rather than carrying huge reserves.
Aim for roughly 60 to 90 grams of carbohydrate per hour, and let the 5 to 8 mile aid spacing keep your intake steady throughout the day rather than front-loading or letting gaps build up.
Keep sodium in the 300 to 700 mg per liter range, and plan for real temperature swings: early October in northern Michigan can start mild and drop sharply once the sun goes down, especially if you are still on course overnight for the 100M.

Most 100 milers loop a single trail system or wilderness area. Wolverine State 100 instead crosses the entire width of Michigan's northern Lower Peninsula, point to point from Petoskey on Lake Michigan to Alpena on Lake Huron. That means varied terrain by design, singletrack trails, gravel roads, limestone paths, and seasonal roads, rather than one repeated surface, and a genuine sense of geographic progress that loop courses cannot offer.
The organizer bills it as approachable for a 100-mile debut, with aid stations every 5 to 8 miles and "generous" cutoffs on the 50K, but do not mistake a point-to-point crossing for an easy day. Covering the width of a peninsula on a mix of trail surfaces over 100 miles is still a full ultra distance test, and the varied footing means your pacing plan has to account for surface changes rather than one consistent grade.
With aid stations every 5 to 8 miles, you have frequent, predictable chances to reset your intake, so build a per-hour plan rather than gambling on long gaps between stops. Aim for roughly 60 to 90 grams of carbohydrate per hour, and sodium in the 300 to 700 mg per liter range, adjusted for October weather in northern Michigan, which can swing from mild to genuinely cold, especially overnight if you are still out on course.

The organizer has not published mile-by-mile cutoff splits for the 100M or 100K. The 50K, which runs as an out-and-back based in Alpena, is described as having generous cutoffs and welcoming terrain, aimed at a broader range of finishers. If you are targeting the 100M or 100K, confirm the current cutoff structure directly with Trivium Racing before you commit to a pacing plan.
The organizer explicitly pitches it that way, "dreaming of your first 100 mile finish," with frequent aid and a course built for approachability rather than extreme technicality. The point-to-point structure and mixed surfaces (singletrack, gravel, limestone paths, seasonal roads) are more forgiving than a purely technical mountain course, which makes this a reasonable first-100 candidate if you can arrange the point-to-point logistics, crew access along a peninsula-crossing route, and pacer or relay support if you want it.
