Mudman Schmudman.  Tough Mudder? Oh Brother.  Warrior Dash?  Too much flash.  Go UFF-DA!

Race Summary:

Welcome to the Uff Da mud run - obstacle racing Extreme North Dakota (END) style. Your hosts, Ole and Lena invite you to participate in an 'extremely' fun and challenging 6K course that will encompass roughly 20 obstacles as it winds its way along the Greenway in Greater Grand Forks.  There are lots of reasons why this race will be different than the plethora of other events that seem to be popping up everywhere these days - so before you choose which one to do make sure to check out our FAQ page, and as Ole would say - "Yust make dat der choice visely!"

Entry includes:  A great race, ENDracing swag, free drink ticket, a big ol' slice of Mike's Pizza, lots of mud, and a commemorative finisher award....(see the faq page for details).

Difficulty: This race is actually about 6K long. Runners who had done similar length 'mud runs' such as Warrior Dash, Mudman, and Hard Charge, and even Tough Mudder unanimously told us that this race was significantly more challenging (well except for tough mudder which is 10 miles long), had tougher obstacles, and had orders of magnitude more mud.  Add to that that this is NATURAL mud (not manufactured!) - some of the finest in the world IMHO - and you've got one heck of a race.  It IS accessible as a first mud run though (it will make every other 6K run seem like a walk in the park) and the 2013 full course was completed by people from 6 to 60+ (no easy breezy courses specially designed for kids here - we know kids are tough and they can tackle the real deal!) but it will take a while!  The fastest elite racer took just under 45 minutes to finish, while some families took up to 2.5 hours.  You always get your money's worth with ENDracing!

Refund Policy:  Sorry, there are no refunds of your registration fee if the race happens. and the race will happen under all weather conditions, unless the interstates are closed.  In event of such severe weather, a modified course may be offered on the same day or an alternate date chosen.  Registered racers unable to make the new date would be offered credit towards another ENDracing event in an amount equal to 75% of the registration cost.  If the event is cancelled entirely due to weather, flood, or natural disaster, all registered racers will receive the 75% credit.  In the extremely unlikely event that the event is cancelled for other reasons (lack of participant numbers, for example), full refunds will be provided, of course.

Wave change requests and official registration transfers can be made here. Waves cannot be changed after online registration closes or at checkin or on race day. If you have registration issues (not wave changes or entry transfers), please email matt@endracing.com
