The Race

Welcome to the ultimate test of endurance and skill on the UK’s longest and fastest kart circuit. At 2.1km, this track pushes every driver to the limit, with a layout that demands full throttle from start to finish – no room for hesitation in this 24-hour sprint race.

With an average track width of 10 meters, overtaking opportunities are everywhere.

The lap

The lap begins with a burst off the start line, navigating the complex camber of the front 'D chicane' before plunging into the sweeping Howells, left-hander.

As you move onto the west side of the circuit, you'll descend towards Rib Bend – a heart-stopping moment where your kart briefly lifts all four wheels off the ground. Stay flat out, maintain control as you touch down, clear the apex, and power through the hill section with a right-hand climb.

Next, you’ll tackle the left turn, climbing relentlessly until you reach the hairpin at the summit. Then it’s a 500-meter dash down the Bob Pope straight before easing off just enough to master the hairpin complex.

From there, it's a swift left-right combination, and back onto the rear straight, setting up for the massive, adrenaline-pumping South Bank – an iconic banked bend that challenges even the most seasoned drivers. Hold on tight, swing through the right, then prepare for the sweeping left that leads into the dog-leg, with one final flat-out sprint to the front straight, crossing the line to begin another lap.

Lap times

Lap times on the International Circuit hover in the low 1:20s, with each driver facing grueling 90-minute stints behind the wheel. This is endurance racing at its purest – every lap a new challenge, with up to 20 overtakes per lap. It’s the hardest race of the year, where only the strongest prevail.
