Revision of Extreme North Dakota Sandhills Ultra Run Experience (END-SURE) from Mon, 03/02/2015 - 09:08

Race Summary: A beautiful trail run with 100K, 50K, and 25K options.  100K race takes in the entire length of the Sheyenne National Grasslands section of the North Country Trail, SW of Fargo North Dakota.  Sections of wide open prairie, pockets of forest, and rugged, rolling 'sandhills' keep the race interesting.  This event is North Dakota's longest footrace and first ultramarathon. The date makes the shorter 50K and 25K options great early season training or final long run leading up to Zumbro.

Location: Sheyenne National Grasslands, approx. 45 minutes SW of Fargo, ND.  Base at Sheyenne Oaks Horse Camp (6050 County Road 23, Leonard, 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 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'.

Lodging: 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. There are camping options available at the Sheyenne Oaks Horse Camp, which serves as race HQ.  This is tent camping or RV camping, with plug in's available. 

Entry includes:  Shuttle service if applicable (25K), a sweet race,  post race refreshments/meal, aid stations, prizes for top three finishers in each 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.
