Turtle River State Park

October 26, 2019 END-TOMBED

October 27, 2019 END-TRAILS


Friday:  Racer check-in and registration from 5-7 pm at See Dick Run (3750 32nd Ave S, Grand Forks, ND). Not required, but if you're in town and have time, checking in on Friday will speed things along on Saturday and Sunday. You'll have to sign a waiver, but bringing a signed waiver will speed things up as well.

Saturday and Sunday:

  • Racer check-in and registration 6:00-7:30 am at Turtle River State Park (TRSP), Woodland Lodge (~3177 Park Ave NW, Arvilla, ND).

  • Required prerace meeting 7:30 am, Woodland Lodge

  • END-TOMBED: Le Mans (running) start 8:00 am.  Racers will start on an approximately ½-mile loop, come back to the bikes, and start riding.

  • END-TRAILS: Running start 8:00 am.

  • The race will last exactly 12 hours from when it starts, as shown on the official race clock at the finish line.

  • Imp racer check-in/registration 12:30-1:45 pm Turtle River State Park (TRSP), Woodland Lodge


Directions: Turtle River State Park, near Arvilla ND. From I-29 near Grand Forks, head west on State Highway 2 for about 17.9 miles. Turn right into Turtle River State Park. Proceed into the park and continue straight, cross the bridge to the TRSP Woodland Lodge. Do not park on the grass.



You need a parking permit for Turtle River State Park (one per vehicle, not per person) which is $7/vehicle. If you don't have an annual pass, you can purchase a pass at check-in. Please ask supporters/other visitors to stop at the park office and get a $7 day pass. Carpooling is best if you can arrange it to both save money and allow more racers to park close to the lodge. DO NOT PARK on GRASS (seriously, please don’t park on the grass).


Camping Info:  

Primitive and RV camping sites are available. Contact Turtle River State Park for reservation and availability.  Fees required, check directly with TRSP at  Please call ahead for arrangements during regular business hours.


Food: A meal (soup, roll, cookie) is included in the registration. One meal per racer. Due to the format of the race and range of times riders may be wanting to eat, second helpings may not be allowed. Racers should bring plenty of their own food.  A microwave and hot water will be available.  The meal will begin being served sometime between 1 and 2 pm. We’ll also have basic fixings (PB+J, bread, ramen) available for people to supplement with. Water and Hammer HEED will be available at the start/finish area.


Miscellaneous:  The Woodland Lodge at Turtle River State Park has restrooms, fireplaces and great viewing windows. There are no on-site food options for guests so please have your friends/fans/family plan accordingly. The closest store is a few miles away. Drinking water available at TRSP Woodland Lodge and campsites.

Cancellation Policy:

Cancellation of the race due to rain, snow, wind or attacks by massive zombie armies is entirely possible and is the sole decision of the race directors in communication with park officials at Turtle River State Park. Notification of cancellation may be made minutes before/after the start of the race. Participants may receive a partial refund to be used at any future ENDracing event. We hope this doesn’t have to happen though. Refund policy.

Course Map:

See recent blog posts at for the whole story...



  • All numbers must be on the front of your bike or body and visible to the timing table at the end of each lap.

  • END-TOMBED: You must physically TOUCH your teammate to make an official transition.

  • END-TRAILS: You must transfer your team bib number to the next runner to make an official transition.

  • All transitions must be made in designated transition areas after passing through the lap check in / finish area.

  • Riders/runners coming through the finish line MUST make sure that their race number is visible to timekeepers.  If you do not hear your number from the timekeepers when you pass through, you need to make sure they saw you (come on back).


Required Equipment:

  • END-TOMBED: Helmet

  • END-TOMBED: Front light and rear light (or rear reflector) for night riding (~7-8pm)

  • END-TRAILS: Head/hand light for early morning and late-race running.

  • END-TRAILS: Method of transferring your number between team members.  Elastic waist belt, other article of clothing, etc.

  • Brrrraaaaaiiiiinnnnnsssssss…….


General Rules  

  • If you or your team drops out, you must notify a volunteer at the timing table (finish line). Note that if a team member drops out (decides not to ride any more laps) it does not affect your team results.

  • Teams consist of up to 4 members.  

  • Cutting the course or any form of cheating (changing course markings, fisticuffs, etc.) will result in automatic disqualification of entire team.  

  • Team/racer with most laps wins, tie breakers will be determined by fastest overall time.  

  • Each racer must check in and out at timing table before continuing.  

  • Each racer that begins a lap must finish the same lap.  

  • Racer changes can only be made in the transition area  

  • Each team will be issued a Race Number (plate or bib)

  • Each racer must wear Race Number for the entire lap.  

  • Loss of Bib will result in a 15-minute penalty.  

  • Transfer of Race Number or tag transitions to next rider/runner may only be done at scoring/transition area.  

  • All transfers of equipment must be done in transition area.  

  • END-TOMBED: All bikes must pass visual safety inspection before entering race course.  Race officials reserve the right to do safety inspections at any time before or during the race.

  • END-TOMBED: Working headlight and taillight (or red reflector) must be used after dusk.  

  • END-TRAILS: Working headlamp or handheld light must be carried after dusk.

  • To pass other riders/runners on the trail be courteous and wait for appropriate locations.

  • END-TOMBED: All on-trail bike repairs must be done by the racers themselves with no outside assistance.  

  • END-TOMBED: All assisted repairs must be done in transition area. Act responsibly and have fun!  


Note for Zombie (solo) racers:

There will be a zombie only transition area where you may leave coolers, food, gear, and anything else you may want during the race. It will be located along the race course directly after passing through the start/finish. You may use this area as a staging area during the race. This is also an area where your support crew (if you’re lucky enough to have one) can hang out and feed you and give massages. Vehicles may be accessed as part of this transition area--in the past people have left transition gear in truck beds, etc.




    • The END-TOMBED course is 10 miles per lap.  You will need ten laps for the Undead Hall of Fame (plus running...).

    • The trail at the beginning of the course has some sections of soft sand, so use caution.

    • Dave’s Tree Branch (after the temporary bridge) gets lower every year, so use caution.


    • The END-TRAILS course is 6.3 miles per lap.  You will need eight laps for the UHOF (plus riding...).
