From the reviews
If you're a driving enthusiast it's important to go during the lowest volume time. They down tune the speed of the carts with more racers on the track. It's fantastic when they allow turned up speeds with good drivers.
Friendly staff, clean and safe environment. Incredible company with great customer service. If you buy 3 races and only stay for 2, you can use that last race the next time you go.
10/10 experience!! I’ve been going to the littleton location for years but now the drive is much shorter with the new thorton store:) the new track and carts make for a really fun time and although there can be a bit of a wait during busy times, they make up for it with their arcade, comfortable couches for watching…
This place is AWESOME!!! We had sooooo much fun!! These karts are no joke!! I was cookin’!!!! Kayla the store manager is running a tight ship!!! It’s so awesome Thornton has another high end entertainment venue!!! Thank you to Nichole and her team here in Thornton!!! We cannot wait to come back!!!!!
