100 Mile

Completed 67 miles (4 loops): scored as 100K finisher; time recorded as of 4th loop completion. If you choose to go out on the 5th loop you must complete the course within the overall cutoff or you will be recorded as an overall DNF (no 100K time will be recorded).

100 K

No drop down option.

Voluntary Event Switching: You can voluntarily choose to drop at the Hog Farm aid station and be scored as described above.

Course: The course is repeat 16.6-mile loops comprising primarily of single-track trail. Besides a stretch on gravel, you'll cross paved roads a few times; there will be no traffic control and your safety will be your responsibility. 100 Mile does 6 loops, 100K does 4 of the 16.6 mile loop (with shortcuts). The courses run clockwise. Total elevation gain (per loop) is about 1500'.

The 100 K course differs from the 100 Mile course in 2 places; PAY ATTENTION TO THE SIGNAGE!

Please note the course may change slightly prior to race day.

Awards: 100 miles gets you a belt buckle and peace sign medal, 100K get you a peace sign medal. Also a very nice certificate of completion to all, available online after the race.
Groovy top 3 overall awards for men and women in all events and 3 deep in 5 year age groups!

Aid Stations: Aid will be at four manned aid stations for each 16.6-mile loop….so if yer countin’, you'll encounter aid roughly every 4-5 miles. We'll serve everything under the sun (and moon!). Soups, sandwiches …. The list is long, click here.

Crews/Handlers: Crews are welcome but are not necessary due to the multiple loops and many runners to hook up with. Access to the runners is at the aid stations only. Crew members are allowed on the course to pace their runner anytime after the 2nd loop. Pacers must wear a “Pacer/Runner Number” bib and must check in and out at the Hog Farm aid station. You will be given your pacer bib at that time. Crew members may not use bikes on the course at any time. Crew vehicles are asked not to drive in and out of campground during the event for the safety of the runners and campers. Please park in designated areas when coming and going. Camper cars that are not moving during the event can be parked at camp site. More pacer info HERE!

Drop Bags: Drop bags will be at the Hog Farm aid station and at the Food for Love aid station so you'll have access to your bags about every 8 miles. The drop area at Hog Farm is under a large tented area to keep them dry. Also at Hog Farm you'll be able to place your own drop bag and anything you want access to; your stuff will be where you put it! We’ll have chairs set up for changing footwear or just to collapse in. Food for Love drop bags will be brought back to Hog Farm semi-regularly (about every 4 hours or so) so we suggest you only put items in that bag that you don’t need back at Hog Farm…and that you may or may not want to retrieve after the race.

100 Mile and 100K parking/rest tents:

All camping for 2024 will be drive-in. If the car is to be used by a crew/handlers during the race, it can't be parked in the campground. We do encourage inviting friends to camp and cheer you on, just park any cars that will be following you in the designated area. Thanks!

Camping: Campsites for friends and crew can be reserved online, see camping link on home page.

Motel listing, location, and phone numbers are shown on the general information page. The park is about an hour drive from Detroit Metro Airport. Renting a car is your best bet to get around.

Sunrise/set: Sunrise – 7:07 AM - Sunset – 7:59 PM (Plus a half hour of civil twilight before and after those times.) (100M/100K will have about 4 hours after the start to see the whole 16.6 mile loop before it gets totally dark.) (The US Navy helps us with this, far out! )

Medical Checks: There will be no medical checks before, after, or during the race. Each entrant is responsible for knowing his or her own physical limitations. We encourage each entrant to get a complete physical before participating in this race. If in the opinion of the race director or aid station captains, your physical or mental condition deteriorates to the point of endangering your safety, you will be withdrawn from the race.
