The 'NUTT' Endurance Challenge is our Ultra Race from the Harrisonburg, VA area.  We couple the ultra with a 25k and a 5k race to include all running abilities.    The route of each race is on the  Mountain Bike Trails built by the Shenandoah Valley Bicycle Coalition.  We have changed the route of the course this year.  This year the route will be a figure "8" that is very close to 10k in distance.  The start and finish of all races will be at the pinch point of the "8".  We will also set up a fully stocked aid station at that point.  Both loops of the "8" are about 5k.  Runners are welcome to leave their well identified drop bags in the aid station area.
