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!

Came here to compare to SB Racing. The cars are electric so no gas smell and they seem to go faster. It was a bit pricier and we had to wait an hour before our first race. The staff were helpful for our first time being there. The only drawback was that they had a couple of regular kids racing with us and they just zoomed around us so fast that it took away from being a first timer. These two kids kept racing with everyone at every race so I didn’t take it personal, I just wished they didn’t put expert racers with newbies. Other than that we had a good time racing. Might come back when it isn’t so crowded and the wait isn’t so long.
