What Adults Say About Events at K1 Speed Ontario

“This location and the experience was phenomenal. I’ve never done anything like this and we did their grand prix package as it was a bachelor party weekend (exotic cars and go kart racing, lots of fun). First, we had three very experienced drivers in our group and I was not one of them. I’ve never even been in a kart of any sort. From my inexperience to current dirt track racing and kart racing drivers we all felt there was zero we’d change and we thought all of the employees were great. Also, of the group, four have been in other street kart indoor racing facilities and they all said this was the best track and the most fun they’d had. Well done k1.”
– Joe T. | 5-stars

“Took my boyfriend here for his birthday, he always has a need for speed and this place was perfect. He couldn’t stop smiling! Pricing was fair, facility is clean and the workers were very helpful. We loved it!”
– Stephanie O. | 5-stars

“I brought a group to K1 Speed for my bachelor party. To say the least we had an absolute blast! The carts go up to 40 MPH which may not sound fast, but when you are flying around those turns there is no way you can floor it. We did a time trial where they compare your own lap times to themselves. After that we did a position round where you truly “place” in 1st, 2nd etc. our group is still raving about how fun it was and we are planning our next trip. I recommend bringing a group of 10 or more so you can have your own track without any walk ins racing against you. I also loved the fact that they give you exact race metrics when you finish each race, and hey getting that 1st place medal around my next and getting my podium picture didn’t hurt either!”
