We booked through Groupon, which helped save a bit compared to regular pricing. Even with a reservation, it was quite busy, so there was still a check-in process at the front — but everything was organized and moved reasonably well given the crowd.I’ve been to another K1 Speed location before, and this one feels noticeably newer and cleaner. The facility is well-maintained, and the helmets were in good condition with no unpleasant odors, which I really appreciated. The overall environment felt modern and safe.We brought a child and asked about grouping them with other kids. The staff were very accommodating and clearly explained the different kart options for younger drivers, making sure everything was age-appropriate while still fun.The track itself was exciting and well-designed, with a good balance of turns and straightaways. The karts were responsive and easy to handle. Overall, a fun and energetic experience — especially great for families — and I’d definitely consider coming back.

Jasmine, Jacob, Jakob, Gavin, Armando, and the staff still are doing a great job making sure everyone stays safe on track. The 5 stars are for them as they are doing great dealing with what they can knowing what I’ll mention in the next part:As a regular I am starting to notice the karts/chargers etc are def not doing as well, as karts keep dying and or have bad tires (flat spots etc).I’d rate that about a 3.5/5 mostly because either they should hire more mechanics, or get newer karts, so that way the workers don’t always have to swap karts mid race or deal with less chill people who will get angry at stuff outside of their control.Props to Jasmine Jacob, Gavin, Jakob, Armando and all of the staff however for still being on top of everything and doing what the can to make racing there worth it, given all the challenges they are facing that are outside of their control.Those workers are why I keep coming back even when it gets frustrating that the karts are needing to be replaced or maintained a bit better.

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

Counter people were great, and so were the the ones checking us in. Only bad thing was one kid was allowed on the track without his seat belt on, so stopped us driving. We lose lap times when we keep getting shut down, that takes some of the fun out. Maybe run newbies with each other only or give us extra laps????

as my sons get deeper involved in Karting, we’ve found K1 to be a great beginners track to get them the fundamentals; going early gives them open track to focus on the racing line and their lap times! Great establishment with excellent and accommodating staff!

Visited on Friday after Christmas, and it was super busy but everything seemed to be going well thanks to the girl with the red hair (I think she said her name was Jasmine?). When I walked in there was a lot of people racing and bumping into each other spinning each other out but I noticed that red hair employee going back and forth to other employees and throwing out no bumping signs.When it was my turn to race that same employee would remind everyone no bumping or they will be removed from the race which I appreciated because it was my first time and I was afraid people might crash into me.However I did pretty good and I think it’s because that girl with the red hair was really on top of making sure everyone would listen to the rules, she even kept people from walking in front of my kart when I was lining up to race!Wonderful spot and thanks to the girl with the red hair for being so on top of safety!
