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 when arriving at the venue. Riders may not pick up their race number plates individually.

For questions regarding the Pit Zone, contact registration services.

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.
