My home track. Always come here to race nearly every week, as well as the adult GP series every first Sunday of each month.The staff is great and I’ve made some good friends there. The manager is also super cool and talking to him you can tell he cares about the people who go there regularly.Definitely my favorite track to race at

Brought my son here for his friend’s birthday party and they had an absolute blast. The setup is perfect — they have a separate adult track and a kids’ track, which keeps things safe and fun for everyone. The staff was super friendly, helpful, and kept everything running smoothly. Overall, a great experience for both kids and adults. We’ll definitely be back!

Celebrated my son’s 9th birthday here for the day and he definitely had a blast. It was just him but he was able to race with with other racers which made it just as fun. They also have arcade games and food while you wait for the next race. Will definitely book a party for him and his friends next time.
