100 Mile

Completed 67 miles (4 loops): scored as 100K finisher; time recorded as of 4th loop completion.

100 K

No drop down option.

Voluntary Event Switching: You can voluntarily choose to drop at the Start/Finish area and be scored as described above.

Course: The course is repeat 16.6-mile loops comprising mostly of single track trail, a couple of miles of gravel road, and the remainder on a mixture of horse trail and rail trail. Besides the stretch on gravel, you'll cross paved roads 2 times each loop; 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). Total elevation gain (per loop) is 1301'.

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 first place overall awards for men and women in all events and 5 deep in 5 year age groups!

Aid Stations: Aid will be at three manned aid stations (one you will hit twice) for each 16.6-mile loop….so if yer countin’, you'll encounter aid roughly every 4 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. (Please don't drive on Kelly Road south of the Grace Aid Station; you'll interfere with the runners.) 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 main aid station at Hell Creek Ranch. 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 across the road and walk in 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 Start/Finish area and at Richie's Haven so you'll have access to your bags about every 8 miles. The drop area at the Start/Finish is under a large tented area to keep them dry. Also at the Start/Finish 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. Richie’s Haven drop bags will be brought back to the start/finish 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 the start/finish…and that you may or may not want to retrieve after the race.

100 Mile and 100K parking/rest tents:

All 100 Mile and 100K runners whose cars will not be moving during the duration of their run will have the option to park a car near the course in the campground, there will be room to pitch a small rest tent etc. You will need to select the "with car" option when you register. Please be advised these spots will sellout. 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 around across the road. 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. The Red Cross will be available at the Start/Finish area. 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.
