The C1 Challenge will speed into the Home of British Motor Racing, Silverstone, this weekend for its now annual 24-hour race.

Taking centre stage around the full Grand Prix circuit, the series will put on a show for those in attendance as it races through the day and night.

Making history in 2019 by having the largest ever starting grid at this very event of 99 cars, the one-make series could yet break its own record with another bumper grid being predicted to take the start.

The Caterham Graduates Championship, Max5 Racing Championship and Sports Prototype Cup will all also be in action over the course of the weekend around the legendary Northamptonshire venue as well.
