Don’t miss the next K1 Speed Enduro Challenge coming to the Inland Empire at K1 Speed Ontario, California. With a solid hour of perpetual racing for drivers to compete against each other, and a mandatory 6 kart change rule, racers will have 85 laps to battle it out for the top spots on the podium! Come out May 5th by 6:30 PM for sign ups with the first race starting at 7:00 PM – entry fee is just $65 per driver and race sessions are each limited to 9 drivers. If more than 9 drivers sign up then we will split the groups. Keep in mind that this is not a team event, this is an individual driver enduro. We are taking early registration – see the front counter staff at K1 Speed Ontario for more information and come race at the best kart racing facility in San Bernardino!
