What is the terrain actually like?
Don't let the "wilderness" label scare you off. This isn't a technical boulder hop. The 50K is roughly 26 miles of single track and 5 miles of dirt forest road. It’s characterized by frequent, moderate ascents and descents through river valleys. It is "rhythmic" rather than "relentless," making it a perfect stepping stone for someone transitioning from road marathons to the trails. You can find the Strava ↗ route for the 50K and the Strava ↗ route for the 27K here.
Should I choose the 50K or the 27K?
The 50K is the flagship experience, starting at 8:00 AM with an 8.5-hour cutoff. It offers the true "remote" feeling of the canyon. The 27K is a shorter, punchier option starting at 9:00 AM with a 7.5-hour cutoff. If you are testing your ultra legs for the first time, the 27K is a low-stakes way to see if you like the terrain, but the 50K is where the real magic (and the maple syrup) happens.
What should I expect regarding weather and gear?
June in Upper Michigan can be deceptive. You might start in crisp, 50°F (10°C) morning air, but the sun hitting those forest roads can heat things up quickly. Expect humidity. Bring moisture-wicking layers and a reliable hydration vest; while the terrain is runnable, the remote sections mean you need to be self-sufficient.
How hard is it to get to the start line?
Logistically, you’ll likely fly into Marquette (KI Sawyer), which is about an hour's drive away. If you are driving from a major hub like Detroit, prepare for a grueling 7+ hour haul. For lodging, the Holiday Inn Express Lakeview in Munising is your best bet for staying near the action and overlooking Lake Superior.
What are the costs and is it worth it?
The pricing is tiered and very reasonable for a specialized trail race. The 50K starts at $115 (early bird) and climbs to $135, while the 27K ranges from $85 to $105. Given the remote access and the quality of the finisher perks, it’s excellent value. Just note that registration closes on June 1, and there are no refunds.
What do I get for finishing?
Aside from the bragging rights of tackling the North Country Trail, every finisher gets a custom medallion and—importantly—Mass Farms Maple Syrup. It’s a local touch that makes the finish line feel a bit more special than your standard plastic medal ceremony.
