Wait, is this madness? No… this is the MAAH DAAH HEY 300! Racers who choose to embark on this journey will HIKE, BIKE or RIDE the MDH BUCK-FIFTY racecourse as an OUT-AND-BACK voyage. Racers will start at CCC Campground, travel south all the way to Burning Coal Vein Campground, then turn around and travel north all the way back to CCC. For an epic round trip of approximately 308 miles of badlands single-track with around 35,078 feet of elevation gain. So far only three people in the entire world have been able to complete this insane feat: Nick Ybarra (supported bike), Corey Kronser (unsupported bike), Sally Nelson (supported run.
