  • Registration for all Unbound Series competitions is available online at Each competition registration will open two weeks before and close 72 hours before the competition. THERE WILL BE NO LOCATE OR DAY OF REGISTRATION FOR ANY COMPETITIONS. (The rule of USASA membership and competition registration is dictated by the USASA organization.)

  • Once the competition registration is confirmed each participant listed will receive a link to a pre-competition "health screen" that must be complete by the athlete and coach from the period not more than 72 hours before the event, up to 12 hours before the event.

Only competitors requiring a bib will need to check in. Check-in closes promptly at 8:30AM, so all participants must check in prior.
