MDH BUCK-FIFTY ULTRA ENDURANCE RACE
About this race
How do you make the RADDEST race, in the BADDEST place just a little bit RADDER and whole lot BADDER? Add on 50 more miles of rugged Badlands single track, and then give people the option to complete it all in one day, two days, three days, or six days of riding… intrigued?
The buck stops here. We are very proud to introduce L.A.N.D.’s most epic race yet, the MDH BUCK-FIFTY. No excuses, no cop-outs, no whining, no doubt about it; YOU are 100% responsible for YOU at this race from training and preparation, to crossing the finish line of one of the longest and most brutal continuous single-track trails in the world. This is one of the RADDEST and BADDEST endurance racing accomplishments a person can aspire to attempt. Your ONLY competition is yourself…
