The 12 Hours of Cranky Monkey Mountain Bike Relay challenges solo racers and teams of 2 or 3 to complete as many 10-mile laps as possible in a 12 hour period, from 8am-8pm.

The absolutely stellar trail network on the Quantico Marine CorpsBase is only open to civilian use on a couple of occasions each year…and this is one of them! With wonderful support from the Marines, expansive transition areas, and great amenities, Quantico is the perfect venue to support a 12 hour mountain bike relay race.

Self-selected classes include:

Solo Classes: Solo Female, Solo Male, Solo Male Masters 35+ (new class), Solo Single-speed
2 Person Relay Team Classes: Duo Male, Duo Male Masters (combined team age of 70+) (new class), Duo Open (at least one female), Duo Single-speed
3 Person Relay Team Classes: Co-Ed, Female, Beginner Male, Sport Male, Expert Male, Masters (combined age of 105+), Single-speed
