100 Mile 100m
Experience the unique challenge of racing 107 MILES of North Dakota’s awe inspiring Maah Daah Hey singletrack trail. This event will push competitive riders to their limits while giving every participant an experience they will remember for the rest of their lives. The Badlands provide a truly stunning backdrop for one of North America’s most challenging and rewarding stretches of singetrack. EXPERT RIDERS ONLY!!! Be one of the very, very few mountain bikers in the world who have the bragging rights to say you finished the MDH100. There is a reason very few people have been able to accomplish this feat... it is extremely difficult. In 2015 only 37% of those who started the race were able to finish! Overall only about 50% of racers cross the finish line... yes, it's that challenging!

This is a very survivable option for kids, families and the very new or very elderly racer! 13 miles of gorgeous badlands single track! Not all, but mostly downhill...

75 Mile 75m
Still a serious undertaking, the Maah Daah Hey 75 is the option most competitive endurance racers should consider choosing if they have never ridden in the Badlands before. It is still a serious undertaking, but definitely more doable for the mere mortals who, for whatever reason, do not commit to the intensive training regiments and disciplined diets of the pros (trust us – it feels better to finish MDH75 and wish you had done MDH100 than to DNF the MDH100 and wish you had done the MDH75).

50 Mile 50m
Best option for the racers who might want to be able to take their kids on a hike in Theodore Roosevelt National Park the day after the race. Just about any serious mountain biker can ride 50 miles if they really put their mind to it. With no river crossing, but more than enough raw and rugged single track for one day, this is an excellent option to challenge your skills and push your limits to the max, but not exceed them.

25 Mile 25m
This is our most enjoyable race option! If you have a few big mountain bike rides under your belt and are ready to take it to the next level test your abilities out on the MDH25 course! This is the perfect entry level Maah Daah Hey race to take your confidence and your bragging rights up a notch! This is the easiest and least technical portion of the whole trail, but it is still the rugged Badlands and NOT necessarily intended for all beginners or first time racers!
