Take on the challenge of a brand new 62-mile multi-surface gravel grinder through the scenic Northeast Michigan countryside and trail system on June 1st, 2024.

This fun and challenging route will take riders from rolling gravel backroads onto exciting snowmobile two-track against the picturesque Devils Lake, then weave through the woods of the Norway Ridge Pathway single/two-track system before cranking down the Alpena-Hillman Trail.

Want to ride but looking for something a bit shorter? We've got you covered! We're excited to announce the addition of the 27-mile Short Course option to race day. The 27-mile course will still take you along all the fun of Indian Reserve Rd, Devil's Lake, and the Norway Ridge Pathway.

We recommend a minimum of at least 33c tires for this route, and you should opt for the cross or gravel bike. There will be some fast rolling hero gravel, slightly rougher two-track, and maybe a lil' bit of (dare I say it?) sand from time to time on the back trails! Just enough for a good time. For those local to the area, stop by our Local Bike Shop Sponsor, Harborside Cycle & Sport of Alpena for your bike-check and tire needs.

This course will be marked, and marks/signage will be made clear in the rider's manual sent out closer to race date to all registrants. All participants are highly encouraged to download and save the Strava Route above to their GPS device to ensure route knowledge and safety. Riders are expected to follow the rules of the road based upon Michigan Bicycle Law.

Once you’ve conquered the course, join us for some great craft beer, spirits, and delicious bites at our official After Party Sponsor location, Hopside Brewery! Hopside is perfectly situated right in the heart of downtown Alpena and within walking distance to many of the city’s entertainment options.

The event is based out of Alpena, MI. Known as the Sanctuary of the Great Lakes, Alpena features plenty of opportunities and experiences for outdoor, culinary, and families against the beautiful, water-centric backdrop of Lake Huron.
