One track in South Yorkshire runs endurance events. Teams share a kart over an hour or more, swapping drivers through a pit stop.
York
Tockwith Outdoor Karting is an outdoor circuit on the former Tockwith Airfield, west of York in North Yorkshire. The track is floodlit, so booked sessions run into the evening all year.
Wakefield, West Yorkshire
Wakefield Indoor Karting is an indoor tarmac circuit at Millenia Park on Thornes Road, south-west of Wakefield city centre. The track includes an 80-metre straight and tight hairpins, and the layout is changed periodically.
Split between four or six drivers, an endurance race often costs less per head than a sprint event, and gives you far more track time.
An hour is enough for a couple of stints each. Two or three hours turns it into a proper day with a real strategic element.
Minimum stop times and mandatory driver changes are what create the strategy. Ask how they run them.
Usually three to six per kart. More drivers means shorter stints, which suits mixed-ability groups.
