The relay consists of 12 pre-determined legs of lengths varying from 2.9 to 5.6 miles. Relay teams select a specific runner rotation order, rotating to the next runner at each transition point, and maintain that exact order through all 12 race legs. Runners must change runners after each leg of the course (no back-to-back legs by the same runner). All teams must provide ONE team vehicle to transport runners to transition points where the batons are exchanged. Teams of 7 or more must provide a van.
