Course POV


Online registration closes on September 8 at 11:59 p.m. No onsite registration, no exceptions.

  • Student-athletes must be “race-ready” in the Pit Zone in order to participate – profile completed, release forms signed electronically, and ACA registration and race entry fees paid.
  • All student-athletes will receive a race number plate and riders will use the same plate for the entire race series.  Number plates have chip timing transponders on the backside so exercise care to avoid damage. Please remove the number plate from the bike before loading it for transport to prevent damage or loss. Replacement number plates will be available at the registration tent for $25.
  • Head Coaches and Team Directors may pick up number plates for the entire team at the registration tent on Friday 2:00-5:00 p.m., and Saturday and Sunday morning beginning at 7:00 a.m. Riders may not pick up their race number plates individually.

For questions regarding the Pit Zone, contact registration services.

The course will be open for pre-ride Friday from 2:00 p.m. until sunset and Saturday following the conclusion of racing (approximately 3:00 p.m.) until sunset. Please pass course workers with care.

Coaches Meeting

A mandatory head coaches meeting will be held prior to the start of middle school and high school racing at the ACA equipment trailer beginning at 7:00 a.m. and 9:00 a.m., respectively. Coaches, this is where you’ll get information about the race day, such as risk management, race conditions and anything else vital that we need to share with you.  Sometimes we need to make changes due to weather or other circumstances so it’s important you’re at the meeting to keep your team and riders informed! Each team must have one (1) representative present at the meeting.

  • Each team may designate one rider in each category to be moved to the front of their respective field.
  • All independent riders will line up with the main group according the random draw order.
At all subsequent races, the staging order will be based on riders overall points standing in that field in the current season for high school and the previous race placing for middle school.

Neutral Support

Mechanics from Trek Bicycle Store of West Phoenix will be on hand to provide free mechanical assistance for any student-athlete with an emergency.  Spare parts are also available for sale at the neutral support tent.  Student-athletes are expected to come to each race with a fully functional, race ready bicycle.  Coaches and adults are not given priority at the neutral support tent.

Food & Beverage Services

Concessions will be available onsite from Singlespeed Coffee Roasters and Stanzi’s Food Truck.


Race day would not be possible without the incredible work of our volunteers. It takes a “village” to put on quality youth mountain bike races. We’d love to have your help and it’s a great opportunity to see a few different sides of how our races operate.  Sign up at

For questions regarding volunteering, contact our volunteer coordinator.

COVID-19 Precautions

The ACA is following the recommendations of the Centers for Disease Control and Prevention, Arizona Department of Health Services, Arizona Interscholastic Association, and the respective county health departments for each race within the ACA calendar.
