Transfers and category (distance) changes can be made yourself by editing your own account, as long as registration is still open and there is availability in the category you desire (fees apply per transfer and/or change).  

In case of emergencies, we reserve the right to change the race or course or terminate the the event early if circumstances arise that are life-threatening to our participants and/or our volunteers. 

Rain Day on Race Day, PLAN B:  If it rains and the racecourse is too wet to ride without causing damage the trail, the race start will be delayed in one hour increments.  If the racecourse is not dry enough to ride by noon, an optional, alternate racecourse, on a different section of trail and/or the gravel roads, will be provided.  Racers may participate at their own discretion.  No refunds, no bad attitudes will be entertained or tolerated.  It is what it is... an adventure. 


*All times are listed in MOUNTAIN DAYLIGHT TIME!  Most of the course is in the MDT zone, however, we are right on the edge of the Central Daylight Time Zone so your phones & GPS units may jump back and forth.  Please plan accordingly.  We recommend setting your devices on permanent MDT zone to avoid any confusion.  If you’re not already confused enough, Watford City operates on CDT zone, but for simplicity: ALL RACE TIMES ARE LISTED IN MDT!!!


PACKET PICKUP:  All racers must check in at Packet Pickup the night before the race.  We offer two locations for your convenience: Watford City works best for the MDH100 & MDH75 participants, and Medora is the most convenient for MDH50, MDH25 & MDH13 participants.  You must go to the location that you specified at online registration. 

5pm – 7pm                Packet Pickup at the Roosevelt Inn & Suites(600 2nd Ave SW Watford City, ND 58854)
