Dual Indoor Tracks

two kids race nose-to-tail at k1 speed ontario during the 2025 us championships

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

A girl plays a claw game in the arcade at K1 Speed.

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.

MORE ARCADE INFO

Recharge with Food & Drinks

Adults eating and drinking at the Paddock Lounge.

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

Adults celebrate on the podium at K1 Speed during a team building activity.

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.
