"This race was by far the hardest thing I have ever done. I love ironman races because of the challenge and the people that do them. I love the crowds, the energy, and the strategy. This offroad ironman had very few people, but quality supersedes quantity."

Jess Anderson, 2015 Female Full Winner

If you do one triathlon this year, do a local, inexpensive sprint, and do it beside a first timer whom you coaxed into the sport #TimeToTri. 

If you do two triathlons this year do Wilderman. It's everything this sport should be! 

Ian Murray, 2017 Male Full Winner


Wilderman Full: 2.4 miles of swimming, 113.4 miles of gravel grinding, mountain biking and stream crossing, and 26.7 miles of the gnarliest trail running in the state.
Wilderman Half: 1.2 miles of swimming, slightly more than 63.8 miles on the bike, and 16.2 miles of trail running.
Wilderman Relay: Full course, but as a relay. Teams of 2 or 3 (since we realize dragging a swimmer up to only do one part of the race is sort of mean). We're even open to letting teams share a swimmer.
Wilderman Aquabike Full: Full course, but just the swim and the bike.
Wilderman Aquabike Half: Half course, but just the swim and the bike.
Wilderman Aquabike Relay: Sign up for the relay and we'll figure it out.

About: This is an epic race. Please--before you decide to do this race read the race reports from previous races (links at the bottom of the page).  Go into this baby with your eyes open... 

If you thought IRONMAN (or even XTERRA) was the end of the road - the big enchilada - the pinnacle of multi-disciplinary solo effort endurance sports - think again.  

Think Harder---Think Better---Think Wilder.

*Please note, the Wilderman IS NOT IN ANY WAY AFFILIATED WITH IRONMAN™ or XTERRA™. It is a triathlon, however, that covers roughly the same distance in each discipline as an IRONMAN triathlon.  As we mentioned, the Wilderman is harder, better, wilder, and a heck of a lot less expensive than IRONMAN™ and XTERRA™ events. Here are some extra trademark symbols in case we missed them somewhere: ™™™™™. 

Profits from this event--and all ENDracing events--will help support Ground Up Adventures, a 501(c)(3) non-profit based on North Dakota dedicated to helping kids get as much adventure as we wished we had growing up.
