The Extreme North Dakota Twelve hOur Mountain Bike of Enduring Delirium is our annual epic halloween-themed bike race. Taking place in Turtle River State Park, riders will ride solo or as part of a relay team to try to get in as many laps as possible in 12 hours. The course has lots of windy single track, some fast double track and even a smidgen of road riding (which you'll be loving by the end!). There is warm place to chill out and get cozy between laps by the fire.  

Although there are hardcore bikers that show up and some good competition, there's also a pretty fun and casual atmosphere - racer-chosen music pumping at the finish of every lap, lots of kids hanging out and cheering on the racers, great volunteers, hidden halloween candy on the course, and a few spooky sections (especially if you're lucky enough to do a lap after dark!) to get you in the Halloween spirit.
