The Kids Dash fee is $10 and its registration closes on race day. Entrants may switch between distances through their RunSignUp profile at no charge. If registrations exceed the event permit limit of 200 runners by April 30, a lottery will be used; legacy runners registered before April 30 are guaranteed entry.
