Had my sons birthday party there, felt it was great with the covid restrictions as they wore helmets, Kids had so much fun. Get out there and race some go karts.

Excellent time at this track. Its one of the best we have been too so far. The adult cars are whippy and go a good speed. Very fun time, and they serve small foods and beverages.

Super fun even for adults. The track is very forgiving and I love how they keep track of the stats and give you print outs. I’ve visited several times over the years and can’t wait to go again.

Place was great! Just know that before you start your race, find out what cart number you are in on the screen above entrance to the carts. Staff is great and very helpful.

Great facility and really nice go carts. A little pricy but it is the only go cart place I know of in the south suburbs of Denver. Also, they have an app that allows you to save your own race times and compare them to others. Recently, K1 Speed was the Denver location for the first annual Mushroom Rally which was basically live action Mario Kart. This was a lot of fun but I hope they add more adult activities to this event in the future.

Love this place I was put in the shifters for the first time today but I was told that we would have boost every 2 minutes and we would be told that it would flash on our screens when it was ready but I never got the shifter thingy on my screen but all in all a great place great people and great racing experience.

The go Carty warties at this race way gave me the most pleasurable automobile experience in recent memory. The air rushing through gaps between my teeth as I smiled with glee, whirling around the track was reminiscent of taking a swig of Gods own mouthwash. Absolutely exquisite. Bravo

I absolutely love this place. The staff were very friendly, they were fast and respectful. I got to race in these fast karts. The outside of the building could use some... badazzle! But the inside of it is stunning! I would 10/10 recommended to someone else and come back again.

I paid 466$ for a party. We had only 6 people, so I was charged for two other people. There was no AC in our reserved room ( it was so hot my cake melted )and my pizza was cold. I was embarrassed to bring my family there. I deserved a discount. My son got three races? I was better off buying him single races and doing his party at a park. Was expecting more for the price.

The staff is amazing and friendly. They are extremely helpful. Made my sons 18th birthday awesome. Thank you all so very much!!! We will be back!

Very Horrible experience. My family was visiting Denver Colorado for a vacation coming from Houston Texas. We payed for 2 races... during the races they were repeatly telling us slow down... no bumping ... no this and that when weren’t even doing that. Another thing I wear glasses and it’s hard to see without my glasses. That helmet is hard to put on with the glasses.. I put my glasses on , but while racing it was very uncomfortable so I let my visor up a little .. after explaining myself he kept telling me over and over ... I will not be back

Called in over a day in advanced. Was told there were walk ins only. Inwas the first one in the parking lot. 2 parties showed up. They then told us our wait was going to be over 2 hours for the first race..... after driving an hour in. They need to work on the management skills. Waste of time.

Used to be cool now theres rude staff, broken karts and just was a waste of money.

This place is a kickass time! I didnt fare so well against the competition, but I had a blast!! This is the trophy!

My 8 year old daughter wants to learn how to race. Come to find out, they have a junior league, totally in on that! Staff was cool as hell, so were good!

Its a fun place to go and the GP league is very competitive with skilled racers. My only complaints are that sometimes people that have no business driving the shifter karts get in them and its a challenge to avoid hitting them, and, ballast weight needs to be added in the GP league. Its not fair that teenagers weighing 100 pounds can constantly dominate everyone else with no hope of ever beating them.

Girls at the desk are not very clever neither is the staff with the go-karts. But the cards are extremely fast and way fun to drive

Been to K1 a few times and had this similar issue. I will call ahead and ask for availability and whats a good time to come in the day before or early morning of, for racing. Then when I show up they will explain I have to wait 3 hours for a race because they lacked the communication to tell us they had parties. For example, I called in saturday for availability for Sunday and a man answered and told me that there are walk ins only on Sunday and had no wait times. So we get there right when it opens and they let a huge party in before opening. We walk in and they tell us we will have to now wait, but not for like a reasonable 30 mins but instead another 2-3 hours because we were no longer a priority. Ive had great racing experiences here but there lack of communication or transparency with there customers is horrible and ruins the experience all together. Let alone they did not care at all that we walked out. No apologies, nothing. I dont ever write reviews like this but they have done this so many times it felt like a need to express how horrible the customer experience is.

So. Much fun with family also very fast very nice outlet for my lead foot

Great place to race. Helpful staff, and easy to get in unless a party is booked. Only wish they would let you make reservations ahead instead of having to come in and then wait.

Great fun for the whole family! Come in and race your best lap! Events, parties or just perfect on a rainy day! Enjoy

Great place to spend time with my son. He loves it, and so does his dad!

Its a fun place but after comming here for many events no one follows the rules. And there policy that you can switch down a class so I can race with my siblings sucks

It was a fun place to go gokarting. The are electric and can really rip, if the people running the track allow them to. They can remotely adjust the speed settings. We did three races, and they never put let us race with karts in high setting. I guess if your bringing younger kids here for a Birthday party then maybe its a good idea, but if you want to go fast like the gas carts then this probably isnt the place for you

Took my 9 year old who had never driven, the staff gave her great instruction and some laps just to get her comfortable. Met and raced with people from all over and with different abilities and yet I managed to lay down some really good lap times. Had a technical difficulty that I didn’t even know about and the floor manager comped me a race without even asking. I asked another staff member how to shave some time off and got 3 great pointers that took off 1.4 seconds per lap. For our first time I ended up being #3 over all at the end of the day. The k1 app is cool for tracking your progress and the Groupon for 2 saved me nearly $30. The only change would be adding some real food types, burgers, dogs, nachos, sodas, etc.Great experience.... we will be back!

It was great to celebrate my Sons birthday.

I had a blast riding the karts, I went with friends and they made it 10x more fun! The staff was okay, everyone seemed a bit tired, but it wasnt crowded and we went in at 7pm

Went to K1 Speed for the first time on friends recommendation . One star for not allowing to go with later batch. Many guys was clubbed to one batch which made it very crowded and the other batch just had 2 guys.Very bad experience. Wont be going to the place anymore and would ask my company outings to be held someplace else.Waste of my money and more importantly my time.

Great times with great people. Membership is worth it if youre competitive at all with your times.

Great place for the family, we have fun everytime we go there!

Good indoor go kart park. Much like most of the indoor places. A bit pricey but a lot of fun. The electronic karts are great. Love the F1 artwork and other decor inside. The data sheets you receive after racing are the best for bragging amongst friends.

Pretty cool, a little pricey and I disagree with sending a kid out on the track 2 times with nobody else. Exceptions should be made to allow a guardian to drive on the track with them and teach them. Staff were good and professional though.

Former Unser Racing employee here. Would recommend this place over Unser for sure. Karts are in better shape, facility is cleaner and it seems safer (not to mention, the management at Unser makes me sick). Electric karts still arent as fast as gas powered karts tho. If youre a skilled driver, you might want to make sure youre not in a heat with a bunch of kids, or slow drivers. They tend to crash a lot & it feels like a wasted race afterwards. Also, I had a track marshall tell me not to hit the brakes so hard... ummm okay, Ill be sure to t-bone the guy in front of me next time so I dont have to brake so hard! But hey, I still had fun.

I recently brought my 10 year old son to drive the adult karts. We had fun but my poor review is due to the fact they allow drivers to drink alcohol before and in between races, which I didn’t find out till after the first race. . This became a big problem with two people (who were clearly drunk) purposely running into other drivers on turns to pass at one point putting my son into the wall causing a big problem with me. I spoke with a staff member about this who apologized and after talking with them found the employees strongly disagreed with this policy and claimed this has caused major problems in the past. Until they change this policy I do not at all recommend this place especially with children.

Fun time! Nice facility. Karts maintained better than most places. Their electric cars keep the experience much cleaner than your older gasoline karts.

Mushroom rally was so fun. The staff was super friendly and made a very enjoyable experience

Nice environment. Wasn’t a lot of people there but we had to wait a hour and a half to drive carts. Not really sure why?

Unwilling to work with a smaller birthday party. Very disappointed. The other location was better. Too bad this is the last one. We will not be back.

I love this place, I went their on a Friday right when they opened and no one was there! The employees are awesome and friendly and I am going back today, I got a free t-shirt and it is awesome plus I got a head sock! I went to bananas fun park in grand Junction and their carts were pretty slow I liked them but I love K1 a lot more!

This place is so much fun!!! Older kids and adults will love it. My office had a corporate event there and it was unbelievably fun. The track and carts are well maintained, the staff was friendly and efficient, and it was as much fun to watch as it was to drive.

My 12 yr old son and I had a lot of fun with racing electric go-karts. The setup was fun and kept us entertained. The price was a bit on the high side. We had fun and will consider going back.

Amazing fun time , employees are ok for the most part they let you race

Fun go cart race track.

Beware if buying tickets online: Their website offers various options for 1, 2, or 3 race packages. If you act quickly and choose your package, you will miss an obscure asterisk lower on the page that tells you that you cant race without paying an additional $7 per person for a membership. I paid online $80 for pair of 2-race tickets for my son and I only to find they demanded another $14 when we arrived. While technically they included a forewarning on their website, I still felt duped by their lack of clarity. We shelled out the extra dough. The racing experience itself was good, hence the three stars.

So much fun! Super fast. However, separating groups somehow would be helpful. Some folks just don’t want to go fast and end up blocking you.

Fast carts and a good track layout that allows for passing

Pretty fun place. The workers there even gave me some tips on how to improve my times. Week days are the time to go because there are less wait times, I got in a race right after I signed up.

We always have a great time here!

Second time to this location. Ive raced at almost every K1 in the Western Region. This is a solid clean well run facility- great staff. Nicely laid out faster track. I did two races, I paid for one and used my free birthday race for the other. I tried the shifter kart but after a few laps I left it in high gear all the time. Second race I used a standard kart which was not even two tenths slower - not because of power or speed - the front tires would not stick - I think they may have been over inflated. All in all great time - go down and check it out. Next time Im in Denver Ill be back.

This place is a riot. Bring your children. I did not expect to have that much fun.

Pretty fun! Be better if they had more high end speed for adults where you actually had to use the break instead of slightly letting of accelerator.

Wow! These guys are great! Helped me out with a few things with no questions asked! Online team does a grate job! VK1 is the best. Will be returning in the future!

Great fun electric karts. Track has interesting striped texture which prevents carts from sliding smoothly.

So much fun!! Friensly check-in staff, awesome track. Enjoyed it a lot and would love to go back when I come back to Denver again!

Awesome facility. Brought my son for his birthday activity. His first time in a kart.He almost broke in to the top 12 laptimes. But did win 4 of his 7 races. Worth the drive from Aurora.

Respectful staff, nice place, and just about what youd expect from a great go karts place.

Good system for keeping the races moving.

I came here today with 5 of my employees . I called ahead and asked if we could come in and race they said they had another small party and the place was dead. once I got there they moved us around told us we couldnt race I was paying my guys by the hour. the staff was absolutely terrible when theyre normally great I will definite doublethink going back

Hello:On January 25th, 2020, my husband (Aaron) and I visited K1 Speed to celebrate his birthday. However, after completing the safety tutorial with your raceway staff, I was unable to find a helmet that fit (due to my hairstyle at the time / large afro-curly hair). The K1 Speed raceway staff apologized, and advised that we would receive a refund.We promptly went to the front desk to address the issue with your staff. The front desk staff appeared unfamiliar with the refund process, and after we pushed (due to not using your services), they offered (and issued without our acceptance) a refund of $17.00 cash. We declined the refund, as our total charge was $76.09. Finally, after too much back and forth, the front desk staff confirmed they would issue a full refund through your POS System, which would be returned to our account within 7-10 business days.Here we are, almost three (3) months later! Ive called numerous times to follow up on the refund, only to be met with theres nothing we can do at this location, but we do see an email has been submitted to corporate to initiate the process (wheres that email???). Additionally, weve physically visited the Littleton location in an attempt to escalate with Management. On March 16th, my husband and I spoke with Nicole Sarno (Assistant Manager) who once again stated that nobody there can assist. We were advised to contact the central Accounting department, and were assured that this group will assist with a prompt resolution.Overall, this experience has been beyond disappointing. Quite frankly, I am not sure how youre able to stay afloat with this level of customer service. We kindly ask that you follow through on your word and our refund of $76.09, or we will be forced to take other action. It may seem like a meager amount (and all things considered, it is); However, we did not render any of your services and therefore that money is not yours. Wed like you to consider this as an opportunity to earn back our trust.Please advise on next steps for issuing this refund ASAP.Thank you,Lynne

I have to say, I was really impressed. The staff was excellent, they knew what they were doing. The facilities are really nice and the cars are great. Very well done, we will be back. Thanks Amanda and (Matt?) and the rest.

High energy, great environment, friendly staff

Normal karts were awesome with the limits turned off. Had a blast in the shifter karts after that, even if I didnt post good times. Track and desk attendants were very friendly.

This place is a rip-off!Eighty-some dollars for three of us to race for three minutes!?! Not worth it!Staff give regulars advantage by putting them up front and give their karts more juice, that’s not fair or fun!They also don’t pay attention, stupid driver caused a wreck and they blamed my kid when it wasn’t even her that caused it!Next time we’ll find somewhere else to spend our money!!

Fun little place, friendly staff. I do wish they had more of an arcade but it was still fun. Normal prices! Clean. I would go again.

Fun times... I won

Very much enjoyed my time here. Saw a special online and went and did 2 races very close to closing time. The employees accommodated me and let me do both races since I was visiting from out of town. Overall great experience. Price is a bit high. Even with the discount it was almost $80 for 2 races for 2 people

This place is a blast! Very friendly staff with fast Go Karts and a fun track. I highly recommend going with friends or family members. Buying 3 races at a time is worth it.

Amazing!!! This place is such a blast, and all the employees are so down to earth. I was surprise that at the end of our race my group got 1st 2nd and 3rd place when i got mine its an actual nice one its not plastic. Whats even better you dont get a ticket for driving fast and crazy!!!

Run by a bunch of kids. Nice place but if you want any other kind of race other than getting paired with a bunch of slow racers youll want to go somewhere else

Very snotty and prejudice staff here. Won’t return to this location again.

K1 is fun, but theres no opportunity to pass anyone else, for the most part. Go-karts are good -- Id say its a detractor that theyre all hooked up to a central computer.Theres potential for a great go-kart experience, but theres too much control on the venues end.

Fantastic event for team building or building vendor relationships.

The staff was kind to our family and helped us rearrange races last second. Clean, everyone wore masks, and plenty of hand sanitizer.

Take your money elsewhere.Everything went wrong. The woman on the register was rude and belligerent from the very beginning. We had questions, she couldnt answer them and instead of getting someone who could she just shrugged and stared blankly at us waiting for payment. I wanted to read a waiver before putting in all my information and she rudely told me that wont be possible, fill out the information first.Our reservation wasnt correct, when two people no showed on us they made us pay for said people anyway. When we decided to leave they said we were still responsible to pay the reservation total, so we decided to just race.Well, we raced and they left our friends off on the tracker that records speed and place in the race. I spoke to another woman regarding a refund for the issues and the people who no showed on us as I had called earlier to inform them there may be fewer of us than planned. I was told that would be fine. I was never notified of having to pay for them still.Corporate was supposed to get back to us. I followed up when a few days went by and I hadnt heard back. Well, I have still not been responded to or refunded for this ridiculous experience. I had set this whole thing up for my boyfriends birthday and the rude manner we were treated in, and the lack of follow through from corporate ruined the experience. None of the 9 of us will come back. If I could give negative stars I would.

Only went in to check it out for a future event but was met with great customer service, they answered all my questions, and they make sure drivers drive safely or they get flagged for lack of control. Prices seem reasonable and I will definitely be giving them my business in the near future. Only wish they had some karts for smaller kids as I have 4 that can do carts but 2 cant here due to height restrictions.

We had a great time and it wasn’t crowded at all

Good fun place for car racing experience

I scheduled a corporate event at K1 Speed Racings Seattle (Redmond) location within the past couple of months. Its my job to set up these type of events all across the country- bringing in food & performing an hour-long presentation for my clients while they eat a catered lunch and then we all enjoy the featured fun team building event offered by the selected venue.Their web site mandated that I purchase our catered food through K1 Racing. Im not sure if this is the case at every location, but at this particular location I had no option to select an outside food vendor for our catered lunch needs.My Seattle-based distributor was able to get 16 of his clients to pull off of their job sites that afternoon to attend my presentation at 1pm, no small feat considering the fact that staying on the job site and getting projects completed is how these people make their living(s). We had promoted the event heavily to make sure that we would have a decent turnout, including a description of the catered lunch we were providing- featuring shrimp cocktail, salad, gourmet sandwiches and assorted beverages.I ordered the food as prescribed by the Redmond K1 Racing venue 9 days in advance of our event (they require a minimum of 7 days advanced notice to provide catered food). I received a confirmation email from K1 Racings Corporate & Group Event Manager thanking me for my food order and stating that the order would be placed with their catering contractor. Upon receiving that confirmation email I assumed that the food & beverage Id ordered would arrive on the date and at the time I needed it to.1:30pm rolls around on the day of my event and I have a group of hungry clients ready to devour the spread of food that Id ordered more than a week prior and nothing shows up. Grace & Brittany, the K1 staff on-site, did everything in their power to help get some kind of food going for our clients, but this facility only has the capability of providing pizza and cookies- not even close to the food quality level I had promised these people. And for some reason they could only cook 2 pies at a time, and hadnt started cooking anything, so my people were hungry, disappointed and the last thing they had the capability to do was pay attention to my presentation.I had done everything in my power to make this event a success. I had emailed my catering order to their Corporate & Group Event Manager well within their required timeline, she confirmed that shed received it and all she had to do was forward that emailed order on to their catering contractor and we would have been fine. For reasons I just cant comprehend, that was too difficult. And now my Seattle-based distributor, along with myself and my company look like morons who cant even properly execute a simple lunch & learn event. To reiterate- I successfully execute these events all over the country (and outside the country) at all different types of venues every other week throughout the year and have never had something like this happen. Why would you send me a confirmation email that my order had been received and was being processed if you hadnt, at a bare minimum, already forwarded my email on to your catering people? Seriously, who does that?For marketing yourselves as a company where you can book the ultimate corporate event you apparently do a poor job. I only hope that my Seattle distributor doesnt hold this against me & my company over the long term. Of course some of the upper management team of my company were in attendance and witnessed the debacle & fallout. BE WARY if youre considering trusting them to properly execute a catered corporate event. I misplaced my trust in this organization and it may well result in damage to my and my distributors reputation in the Pacific Northwest Region. If you dare, make sure to inquire about obtaining any catered food from an outside vendor who will actually show up with the food and drink that you order on the date and time that you ordered them. If they dont allow you to do so, FIND ANOTHER VENUE.

Most fun weve had in a long time! Great staff and overall experience!

Really fun electric carts. Fast and exciting racing with your friends.

K1 hosted the Mushroom Rally for the Denver area and it was fantastic!

What a great event at k1 speed. Would be great to have more effects like this

Was at K1 for our club party on Sun Nov 17 . The facility, management and staff were great, they went above the expected for our group and everyone had a fun time. Would definitely go again.

16 year olds with a power trip. We will not be back. A group of 9 left very disappointed at $80/person

This place was really fun and they make sure you are safe so you dont get injured and the people there are pretty nice.

Great place for have fun, even when outside its snowing so bad, the costumers its gente and helpful, nice track, I advise to take the kart with 3 gear, its more fast and funny, if you dont know how to drive, its not tha bad, after the first lap you learn easy and quickly.

Love this place. Had such a great time. Hope to go back soon!

Have a lot of fun here I should have won but they flagged me down

Went here for a date with my boyfriend and had a fantastic time and got amazing customer service!!

The experience itself wasnt the worst out there, but I saw a little girl in the adult racing group, who was going less then 2mph and none of the workers got her out of the race and let her be in danger of getting hurt through that entire run. Unsafe place.

Young kids have to be at least 4 feet tall to go on a go-kart by themselves. Its a great place to go...

The staff is friendly and do there best to minimize the wait time between races.

This place is a blast. Fun for everyone over 4 feet. We went to a birthday party and ended up all the dads battled it out. Nothing not fun about driving your friend into a wall at speed. While your kids cheer you on! Oh and the kids had fun driving too.

It was very fun! Had a group of eight and these were the winners!

Absolutely love this place! The carts are fast, and the races are always fun. Especially a great place for large events and birthdays. Would recommend

These Go-Karts are fast! The karts are eclectic so you’re not gagging on gas fumes like some indoor tracks. I’ll definitely come back.

Went here for a friends birthday had a really great time. They had a little trouble with the scoring, one of my friends wasnt even on the board the first lap. And I know my first slap that I left at least two people twice but somehow I still came in fourth.The only other thing I didnt like was that if you make a reservation for a party if someone doesnt show they still make you pay. But its a super fun group activity and you can go pretty fast!

The track is great and karts are well maintained, nobody can complain theirs was too slow.

A fun indoor go cart racing facility. Carts are electric so there are no fumes. Its also very safe as operators can set speed limits on carts and shut down carts if there is an accident. A fun place for a birthday party.

Such a fun place to take family!
