Race Information

June 13, 2020
Grand Rapids, MI
5 or 10 Hours


Experience some incredible mountain biking, trekking land, rivers and lakes just miles from the metropolitan Grand Rapids area. Travel by canoe, bike and on foot, navigating 5-10 county parks and other public and private ands by map and compass. Choose from the not too difficult 5-hour beginner/intermediate race or the more challenging 10-hour race, Racers in both events will celebrate the adventure with a hearty post-race taco bar and award/raffle ceremony.

These races will feature incredible mountain bike trails, lakes and rolling land for trekking and orienteering in the Cannonsburg, Ada, and Lowell areas, just east of Grand Rapids. Enjoy Beer City USA breweries, nightlife, Frederick Meijer Gardens, Lake Michigan beaches and other area attractions before or after the race.

Estimated Miles
Trek/On-Foot: 4-6 miles
Bike: 14-18 miles
Paddle: 2-3 miles
Most, if not all, checkpoints are optional so you’ll be able to get back to the finish in time. You can do this!

Trek/On-Foot: 8-14 miles
Bike: 25-35 miles
Paddle: 3-6 miles

Plan on biking on two-tracks, gravel roads, beginner and intermediate singletrack, and paved roads. The singletrack biking will be a highlight. Trekking will be on mostly rolling terrain. Most checkpoints (CP) will be on defined terrain such as hilltops, gullies/reentrants, etc. but some will be more subtle in the 10-hour race to test experienced racers. You will not need to cross treacherous or extremely swampy terrain to reach checkpoints, especially in the 5-hour race. Paddling will be on flat water.

Orienteering Practice/Clinic

  • Map reading will be important; orienteering will be mostly beginner to intermediate level. Some advanced CPs in the 10-hour race.
  • Navigation 101/201 clinic, _____ at Seidman Park in Grand Rapids. Click here to RSVP on the Facebook event page or contact us
  • If you can’t make it, check out the Navigation 101/201 clinic presentation on our Learn More page for tips.



  • See the Required Gear page for details on what you need to bring or carry.
  • Road bikes not allowed due to moderately rugged terrain in spots. Beginner and intermediate biking.
  • We highly recommend mountain bike tires (2″ or more) or 40c+ gravel/cross tires.
  • Required gear has been reduced to primarily safety items to keep your costs down. See the Recommended list below Required items for additional items you may want.


  • Campgrounds: Wabasis Lake, Scalley Lake


  • We would encourage you to invite friends and family to camp and then watch the race.
  • We will offer race maps to spectators so they can try to follow you. Even better, have friends and family volunteer!

Check-in, Pre-Race Briefing, Race Components

  • Check-in. We recommend arriving to check-in early as we will hand out maps then and you can get most or all of your route complete before the pre-race meeting.
  • Pre-race meeting. We’ll go over rules, answer any questions, explain the passport and hand out an instruction sheet and maps.
  • Passport. The passport is the piece of waterproof paper you’ll punch at each checkpoint to prove you found it. You must not lose it!
  • Flag (control) and Punch. You are looking for orange and white 3-sided orienteering flags (technically called the control marker). You must punch the correct box in the passport so we can verify you were indeed there. A card with a number will be attached to the flag. Check it to confirm you got the right one.
  • Race instructions/clues. Lists key rules, describes the course and the activities, and provides hints about where checkpoints are located.
  • Maps. The map(s) will almost always be topographical but may be aerial if accurate topo information is not available. Most, if not all, checkpoints will be shown. You can waterproof your map with packing tape or contact paper if desired (find at Meijer-type stores). Either way, we recommend keeping it in a waterproof map case or zip lock baggie at least.
  • Goal. The goal is to maximize the number of checkpoints on your passport within the time limit. A team that gets 25 checkpoints with one minute to spare will finish ahead of a team that gets 24 checkpoints with one hour to spare.


  • Transition Areas. Transition areas are locations where you switch between one discipline and another (trek/orienteer, bike, paddle). TA flags are usually mandatory. They are almost always manned by a volunteer. Always carry cash in case you need fluids or food at a store you pass by. It’s your responsible to punch the TA flag, often when arriving and departing so we can capture your split time and track teams. Teams often switch shoes and other gear at TAs.
  • Orienteering. In most cases, checkpoints will be optional and can be found in any order within an orienteering section. We will note which checkpoints are “advanced.” Teams that are not going at a fast pace should consider skipping these as they require going a significant distance or over dodgy terrain to obtain. They are meant to challenge the elite teams trying to obtain all CPs. Map reading will be critical. You should also know how to use a compass. Checkpoints may be out of view (especially to deter theft if they are in public places) but are not intended to be difficult to spot if you are in the right place.
  • Biking. Bike sections will be a mix of gravel, paved, two-track and singletrack sections (beginner to intermediate; no highly technical/ dangerous terrain). No road bikes allowed. Checkpoints are usually along side the route but may require racers to leave their bikes and trek or bushwhack with their bikes off-trail. Racers often wear clip-in bike shoes and then switch to running shoes for longer orienteer/trekking sections within the bike section (which is often the majority of the race). Sometimes CPs are not indicated on a singletrack trail on the map so that teams can’t bushwhack or ride backwards to get them. Sometimes it’s allowed. Safety often dictates which way we do this.
  • Paddling. Our races try to keep paddling time at a fairly low ratio compared to biking and trekking because it’s harder to train for and often less navigation-based and/or appealing to the average racer.

Join us after the race for the post-race taco bar and awards/raffle. Beer and other alcoholic beverages available for purchase. We’ll pass out some great prizes to the top teams in each division. We’ll raffle off a bunch of stuff too.
