The Extreme North Dakota Terrifying Run Amongst Innumerable Lost Souls:  it's our annual epic Halloween themed trail run.  Taking place in Turtle River State Park, runners will compete solo or as part of a relay team to try to get in as many laps as possible in 6 or 12 hours.

 

The course has lots of windy single track, some fast and flat double track, lots of undulations (this is North Dakota, don't worry too much!) and about 100 yards of pavement.  It is a beautiful place to run!

Zombie 6/12/24-Hour: Race solo for 6, 12, or 24 hours to get the most number of laps of the course.

Skeleton Army 12/24-Hour: Race with a team of up to four people for 12 or 24 hours, alternating laps.

Imp:  ~10k trail run.  Register as an Imp and get a taste of the race without spending all day at it.  Race solo for one lap of the course, refuel, and just think about upgrading to Zombie next year...

Scoring:  Racers and Teams are first ranked based on the number of laps completed (in under 12 hours) and then by the time in which the last lap was completed. Depending on conditions, 50 miles is a pretty hardcore benchmark to shoot for.

 

Other Details: This event forms part of the entry requirement into the Undead Hall of Fame.  In order to achieve Undead Hall of Fame status a racer must complete 100 miles in END-TOMBED and 50 miles (on foot) during END-TRAILS in the same weekend. Good luck. You're going to need it.
