Our club (in Oz) runs a yearly enduro. Teams are made up of three drivers, covering the three classes we run in the championship, so everybody can play, no need to buy anything you don't already have, restrictions are the same as per the championship. Each driver drives 1/2 hour, changeover is on the siren sound, no need to stop the race. Great fun for everyone and sometimes nail biting finishes but the race is won or lost in the pits on the battery changes. Repairs to the cars are allowed during the race.
