Went on a Saturday morning when they opened, employees were very patient and helpful. I had my two kids plus their friend so if you could imagine how much energy they were producing. The pit crew gentlemen were a fun bunch and helpful racing was intense not gonna lie, It feels like a full body workout, and I would love to go again.Pretty cool they send a print out and you can see your fastest lap on a piece of paper and see what you placed

Certainly enjoyed my visit here this past weekend. Went in a bit early around 11 am, so lucked out having an open track for a 1v1 race. Second race had more people on the grid, so pace was a bit slower. The electric karts have some fun acceleration and grippy cornering to whip around the circuit.Hope to come here again someday, perhaps for a family get-together.

Had lots of fun. Racing the Go Karts definitely gets your heart pumping and wanting to better your overall time. My son and I walked away with life long memories we can share with friends and family.

Hi 🙂 I always have a great time whenever I go to any of the K1 Facilities! Being on the track is my happy place for sure, my wife and I went together this time and she had a great time too. There was a couple birthday parties going on too. The wait time between our races was pretty quick and there was quite a few people there that day as well. I totally recommend bringing your kids to learn to drive too. Fun, safe and they should have a great time too
