This is a marathon relay that includes 26 laps of a 1 mile loop. A full team is 5 runners, but you can have make the race more challenging by splitting the laps up with fewer teamates. Teams can divide the legs up and run the legs in any order but must change runners after each lap. Ideally, a team would run in order to get as much rest and to refuel before running again. However, there is no rule in place for team running order.
