100 Miles

A tour of the Upper Peninsula


You are on your own. You are responsible for your preparation, readiness, choices, and ultimately the outcome. Solo events will utilize GPS navigation. The course is not marked. Required gear lists are provided, may be updated prior to the race, and are considered mandatory. Failure to pass gear check will result in DQ.

Road rules apply across all event categories. Traffic will be active on course. Volunteers WILL NOT be posted at trail or road crossings. Be alert. You’re signing up for an Adventure. In an emergency, dial 911.

We’re not trying to scare you or brag about how hard the day will be. We want you to understand what you signed up to do. We want you to understand the penalty for underestimating the challenge, or poor planning. Both could result in undesired consequences.

You can do this. CRUSH your comfort zone.

Download the 100-mile GPX file

Some users and web browsers have issues with GPX files. We will assist in loading onto your GPS unit at Basecamp on Friday night. Until then if you’re having issues call your techy friend who has done this before. This is not the final GPX file and is only a sample, but close enough for scouting, recon and general course knowledge.


An Enhanced Gravel Loop beginning and ending at the Forestville Basecamp. You, a couple hundred friends, and the wild U.P. In our opinion, a better day on the bike does not exist. We’ve provided a “concept route” and “concept GPX-file”. We recommend you follow our Facebook page , and occasionally check back for updates to the map and/or GPX-file.


You will be provided a booklet in lieu of a number plate. Traditional race plates are dead to us. Think of your passport as your number plate. DO NOT LOSE IT. You’ll need it at checkpoints and at the finish line. The passport will contain helpful information such as: required gear checklist, the rules, course information, bail point information, and more.


This is your basecamp: Forestville Trailhead rustic camping.

We have reserved Forestville for the weekend. Sites can be claimed on a first come-first serve basis. As the event approaches more information regarding basecamp will be provided. Be respectful to the event staff and each other. Respect the property. You are not required to camp at basecamp Saturday night but you need to be there Friday night. Start times will not be random this year.

In the event you choose to camp with us, your camping has been paid for. If you feel guilty, donate to our youth programs. The money will be used to empower kids through outdoor adventure!

Many racers will arrive in the U.P. with family and friends planning to serve as a support team. We encourage this activity, but please be advised we are working on and will issue some guidelines intended to manage where and when support can be provided. The most likely answer will be in one of the predetermined checkpoints. Stay tuned for more information on the topic.
