We require marshals to keep the site safe, when in the wooded quarry you get to see the trucks in action, up close and personal, so an excellent experience in its self, so the Syncro curious and 2wd peeps more than welcome.And of course... Drivers with vehicles to carry the passengers on the laps.We don't expect you to give up the whole weekend (But you can if you like) but we do ask that you are available for a whole session (Approx 2 and a bit hours), last year we ran 2 on Saturday and 1 on Sunday with 3 vehicles running constantly in each session. 3 is about the correct number to ensure non stop action 4 is a squeeze and usually means pauses in a couple of spots on each lap, but manageable.
