We'll give you some phone numbers at the race start for emergencies. If you have questions before then, feel free to contact us in any number of ways:

Start times

May change for 2016.

  Start Time Cutoff Time
100K 8 AM Midnight (16 hours)
50K 11 AM 7 PM (8 hours)
25K 1 PM 5 PM (4 hours)


Sheyenne National Grasslands, approx. 45 minutes SW of Fargo, ND.  Base near Sheyenne Oaks Horse Camp (6050 County Road 23, Leonard, ND).  

During the inaugural year (mid March) runners faced over a foot of brand new snow on the trail.  You should be prepared for an 'all conditions race.' Yeah, it is possible that the trail will be dry and in awesome conditions, but it isn't exactly likely.  While we expect some sections of dry and fast runnig, we also expect challenging sections of the race including plenty of miles of 'spring conditions'.

Rough END-SURE elevation profile (click for larger).  Arrows show directions of 2014 race.  2015 race was the same for 100K; 50K was an out-and-back on the right half (starting from far right); 25K started in the middle and ended at the far right.


Some accommodation is available in Lisbon ND, which is about 25 minutes from race start.  Fargo, ND is the nearest major city with ample accommodation options and is about 45 minutes to 1 hour from the race start. 

Event Waiver

Waivers will be available online before the race.  Please print one and fill it out and bring it to pre-registration/registration.  We will have extras in the event you forget.  You will not be allowed to race without a signed waiver.

Gear List

Although there will be several aid stations, racers should be prepared to be self-sufficient and will be required to carry a minimum amount of gear.  This gear list may be modified prior to race day depending on weather forecasts and/or actual race day conditions.

Emergency contact numbers will be provided upon check in. It is your responsibility to program these into your cell phone to be used in case of an emergency that requires assistance from staff organizers. It is recommended that you keep your cell phone off until you need it. If your battery is dead because you are taking selfies at every mile marker and posting them to Facebook we will not feel sorry for you when you get lost and get severe frostbite because you are unable to call for help.

Bold items are required.  Non-bold items are recommended.

  • 100K racers will be allowed 1 small drop bag to be carried by race organizers to the 50K mark of the race.  The headlamp/flashlight can be part of this drop bag.  The bag must be clearly labelled with your name and sealed to prevent articles from coming out.  You may leave anything you want in the sealed bag when you start the second half of the course and it will be brought back to the finish line for you.  Articles not put in your sealed bag will be thrown in the trash.
