Athletes must be citizens or legal residents of North America or Central America to be eligible to compete.
Age Group athletes compete in their Age Group division based on their age on race day. Additionally, athletes must compete in the same divisions across different events (e.g. if an athlete races Pro in the 3K, they must also race Pro in the 15K).
Registrations can not be deferred and are not refundable or transferable to other individuals, unless they are protected by Ticket Guardian insurance.
There are a limited number of combo tickets available HERE for athletes wishing to compete in both the North American Championships and the World Championships. These discounted tickets are strictly limited and available on a first-come-first-served basis.
