Our friends at USAC have changed the eligibility requirements for Collegiate Nationals gravity events.
For mountain bike, to race the gravity races (DH, Dual, MTX, or DS) at MTB Nationals, a rider must have raced the gravity races at their conference championships as an A category rider in addition to one other gravity race that current season as an A category rider. Riders who do not participate in their conference championships must have competed as a category A racer in their final three gravity conference races during the current season.
