DETAILS
Dual Indoor Tracks
Whether you’re racing high-speed laps, hosting a kid’s birthday party, a teen celebration, an adult birthday event, or a corporate gathering, we deliver the high-speed thrills and the fun you’re looking for. With arcade games, a comfortable casual dining lounge, and two air-conditioned party rooms, K1 Speed Ontario is your go-to spot for unforgettable indoor action near Ontario Mills, Upland, Rancho Cucamonga, and Pomona
This 85,000 sq ft venue features two asphalt indoor tracks.
Track 1
Track 1 challenges racers with its 11-turn layout. The lap begins with a double-apex right, followed by a sharp left hairpin at Turn 3. Take a wide entry into Turn 4 and aim to hit the apex of Turn 5, setting up a strong exit through one of the fast parts of the track. Lightly feather the brake after Turn 6’s right to prepare for a strong entry into Turn 7 and its wide left hairpin. A sweeping right takes racers up to another right hairpin in Turn 9. It’s all-out on the accelerator through Turns 10 and 11, bringing racers back over the Start/Finish Line down the main straight.
Track 2
Track 2, typically reserved for junior racers, has 10 turns — ranging from hairpins to double apexes. The track also features a few straight sections for high-speed action.
Arcade Options
Between races or during celebrations, head to one of our 20 arcade games for nonstop fun. Located near the track, keep your eye on the action while racking up some high scores! Choose from titles like Super Bikes, Hoops FX, FunZone, and so many others, it’ll be hard to pick a favorite.
Recharge with Food & Drinks
Take a break in our Paddock Lounge, a stylish restaurant area, featuring a tasty lineup of appetizers, burgers, wings, pizzas, desserts, and more. Order at the counter, then relax in comfortable seating. And for those 21 and over, a selection of beer and wine is available after racing, offering a mellow way to wrap up your visit.
Group Events for Any Occasion
And if you’re looking to host a kid’s birthday party, teen birthday party, adult birthday, bachelor/bachelorette party, corporate event, or team-building exercise in the Inland Empire / Ontario area, then K1 Speed is here for you! We’ve got everything you need to make your event memorable: private racing, a reserved time, delicious catering options, and private meeting spaces for conferences or celebrations. The Fontana Room has a max capacity of 30, while the Irwindale Room can comfortably seat 50 people. Guests often choose to host their events in the Paddock Lounge (28 max capacity) due to its open atmosphere and constant view of the go-kart tracks.

We’ve been here a few times. The first time was for a kids birthday party and that was an awesome experience. We got there right when they opened so it wasn’t too busy. They have a snack bar and two areas of racing, one for adults and one track for kids. We had an awesome time racing with our adult family and my kids had a blast racing with their cousins. It’s a great place to go have fun with friends and family!

I celebrated my son 14 th birthday on Sunday and all the staff was really nice and helpful. My son and friends had an amazing time, food is actually good and everything was served at the perfect time for the boys after they were racing . I definitely recommend this place for birthday parties or any other celebration.
