Club100 Racing

The fastest "arrive and drive" kart championship in the UK

Premier Endurance Championship 2018

Championship information

The Premier, Clubman and Intermediate classes are run as one event. The Premier Class is the highest standard of endurance racing offered by CLUB100 and is designed for the fastest and most experienced teams. The Clubman Class is for experienced teams that are aspiring to break into the Premier Class. The Intermediate Class is designed for remaining regular teams who have raced previously in the now deleted Inters/Rookie Class and new teams wishing to race with us for the first time. The series is run over 12 rounds, with each team’s best 9 results counting to the championship.

To create a level playing field, all three classes run a minimum weight limit of 85kg, the knock-on effect being extremely close racing.

  • Practice – 35 minutes
  • Qualifying – 10 minutes
  • Race – 2 hours

Kart allocation

Each team’s Kart is randomly allocated on the day. To avoid confusion, teams carry the same number for the entire season.


Practice is 35 minutes and is generally used by drivers to familiarise with the circuit and give the kart a shakedown. From 5 minutes in through to 25 minutes, the Club100 test drivers are available to test the karts and make any necessary adjustments. The test drivers carry their own timing transponder to ensure each Kart is within an agreed tolerance. If the tolerance time is not achieved, the team are offered a replacement Kart. At the end of practice the green flag is shown signifying the start of qualifying. At the same time the refuelling bay is closed and anyone not in the queue will not be allowed to refuel until 2 minutes into the race.


Teams have a 10 minute qualifying period in which to post a competitive time. With the refuelling bay closed, this will add an extra tactical element as teams will need to choose whether to use the whole 10 minutes or do a couple of flying laps then pit to conserve fuel.

The Race

Fuel-windows and strategy

Each team must make a mandatory fuel stop 5 times during the race. Stopping at least once in each of the fuel windows listed as follows –

  • Window 1 – 2 Minutes through to 20 Minutes
  • Window 2 – 25 Minutes through to 45 Minutes
  • Window 3 – 50 Minutes through to 1 Hour 10 Minutes
  • Window 4 – 1 Hour 15 Minutes through to 1 Hour 35 Minutes
  • Window 5 – 1 Hour 40 Minutes through to 1 Hour 55 Minutes

Teams must take on a full tank of fuel on each of the 5 stops.

Pit stops

With racing being so close, pit stops play a vital part in the race’s final outcome. With grids of up to 35 karts and only 2 fuel bays, finding a window to refuel without having to queue is not easy. Some teams adjust their strategy to avoid the busiest times whilst others rely on pit to driver communication. Once in the fuel bay, the refuelling marshals take over. During this time the team can change any seat inserts or lead for the next driver. Teams will need to be slick and find ways to change drivers, adjust pedal settings and change over any ballast quickly.
