Take on the challenge of a brand new 62 (or 27!) mile multi-surface gravel race through the scenic Northeast Michigan countryside and trail system on June 1st, 2024.

This fun and challenging route will take riders from the rolling gravel backroads onto exciting snowmobile two-tracks 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.


Each registrant will receive a shirt and sticker with registration!

When: June 1st, 2024
Time: 8:00am (may be subject to minor change based on weather)
Start/Finish – Where: Thunder Bay Jr High, Alpena, MI 49707

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.

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.

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. For ideas on things to do and lodging, check out Visit Alpena:

For those of you unable to attend, we will be hosting a virtual rider challenge on the same day as the race! Compete in a variety of challenges such as longest ride, most elevation gained, etc. More info on challenge details will be sent to virtual riders as we approach race date.
