Pre-Riding
Tuesday, Thursday or Saturday for the correct flow (Yankee Springs Deep Lake trail switches flow daily). Your best start/finish is probably at the Thornapple Township Hall a short ways south of Camp Manitou-Lin on Briggs. Refill water at Deep Lake Campground at Mile Please stay off camp property except on race day.

Course Markings
All race courses will be marked with directional arrows. The 38-mile course will have volunteers or sheriff monitors at busy intersections in addition to arrows. Some intersections will only have arrows. Racers are still responsible for crossing when safe to do so. We highly recommend that you print the Cue Sheet in case signs fall down or are stolen. GPX/TXC tracks are not required but may be helpful if you have a navigation device.

It’s a dangerous business, going out your door. You step onto the road, and if you don’t keep your feet, there’s no knowing where you might be swept off to.

Course Description

  • Roll-Out and First Singletrack Section: After a 5-mile roll-out from Camp Manitou-Lin on mostly gravel, you will climb the infamous Bassett Lake Road hill. If you aren’t thinned out by now, this hill will certainly thin out the herd. Look for the Section C medical sign for your turn-off to the right (and signs on race day of course) where you’ll enter into the famous and revered Deep Lake mountain bike trail system at The Pines for 5 miles of fast fun. Take a quick left and follow the trail along the road before turning right and climbing into the ridge of pines. After some intermediate-level riding with a few moderately technical spots (watch rocky descent video here for one of these spots; nothing crazy relative to other trails in the lower peninsula), the most challenging of the day, you’ll have some windy but fast trail. As you approach the campground, keep some off-shoot trails to your left. You’ll follow the normal Saturday flow which is clockwise (opposite from the traditional flow), taking the trail eastward toward Deep Lake and then south, hopping off the singletrack at Gun Lake Rd., just west of Yankee Springs Rd.
  • Gravel & Two-Tracks: Enjoy some wider stretches over the next 17 miles, although a few will feel like singletrack in their rugged surface and need for picking the right line. You’ll head east, with a steady climb on pavement before accessing several miles of awesome gravel, including the beautiful Audobon Sanctuary where we hope to have the aid station. After surviving the infamous Sager Road (our version of Mordor perhaps?), you’ll hammer a few more miles of paved and gravel roads throughout Middle Earth.
  • Final Singletrack Section & Finish: You’ll finish the race with a final 4 miles of pure Deep Lake awesomeness, entering in at Graves Hill and exiting at The Pines where you first entered back at mile 5. Plummet down the Bassett Lake Road hill – it will feel really good after 30 minutes, but make sure you stay in control! Finish in reverse of your first 5 miles on mostly flat gravel and a final push on pavement until you reach camp, aka The Shire.
