Location: Sheyenne National Grasslands, approx. 45 minutes SW of Fargo, ND.  Here's a Map.  During the inaugural year (mid March) runners faced over a foot of brand new snow on the trail.  We've moved the date a bit later in the spring but you should still be prepared for an 'all conditions race.' Yeah, it is possible that the trail will be dry and in awesome conditions, but it itsn'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'.

Lodging: Details coming Fall 2014 for 2015 race. 

Relay details: Participants in the relay category will transfer bib numbers at approximatley the half way point through the course.  Maps to this location will be provided.  Runners doing the second leg should provide transportation at the switch off location so that the first leg runner has a way to get to the finish line - we will not provide transportation to or from the half relay switch location. 

Entry includes:  Shuttle service if applicable (50K and relay), a sweet race,  post race refreshments/meal, aid stations, prizes for top finishers in all categories (depth of prizing depends on racer numbers), and finisher awards for all 100K finishers.  2014's finisher awards were hand-made and etched wine punts--100% repurposed materials and local craftsmanship! ENDracing swag will be available as an add on items during registration at dirt cheap prices.
