SoCal’s club for more than 50 years. Local, competitive, and run by people who care about the sport.

The short version
Tri-C feels local. The folks running it are great and care a lot about the sport in general. It’s much more competitive than arrive-and-drive leagues like FAT Karting League, but not at the level of COTF or SKUSA. They try to keep events to one day when they can to hold costs down, they really listen to drivers and families, and they work hard to keep it accessible. The Tri-C community was the standout for us. Folks are just kind and supportive. If you own a kart in SoCal, this is probably where you should race first.
Where Tri-C races
- High Desert: at Willow Springs.
- California Nights: Saturday nights at Apex.
- Sagebrush Classic: at Spring Mountain.
- Chill Challenge (winter): one round at Apex, two at Adams.
- 2027 Club Series: eight rounds at Adams and Apex.
- IKF Grand Nationals: Tri-C hosted it at Spring Mountain in 2026.
Every Tri-C date is on the SoCal karting calendar. Lap times for each track and layout are on the track pages.
Night races
California Nights is super fun, but it’s hard on the little guys with 8 pm bedtimes. Depending on how the day runs, podiums can be at midnight or later. Plan the drive home.
Tri-C classes
Kid Kart, TaG Micro, TaG Mini, Briggs LO206 (Cadet, Senior, Master, World Formula), Tillotson T225 Junior and Senior, 100cc TaG (KA100 and X30) Junior, Senior and Master, and Open Shifter.

Every series requires neck collars for the kids, so that one isn’t a difference. Read the Tri-C club rules once before your first race.
A Tri-C race day
Practice, qualifying, a heat and the main, in one day when they can manage it. There’s a mandatory drivers’ meeting, and kid classes need a parent or coach there with them. By the end of a Tri-C weekend the porta-potties are wrecked, which is rough on moms in particular. Bring wipes and your own toilet paper.
Who races here
Mostly SoCal families, and a lot of them on their own. Across the 2026 season (11 rounds, 932 entries) 21% of entries listed no team, and privateers took 19% of podiums and 17 of 116 wins. Where that holds and where it doesn’t: half the Kid Kart podiums and about a quarter of the Micro, Mini and LO206 Cadet podiums went to privateers; in 100cc Junior and Senior it was 9%, and in World Formula 7%. The tents: Precision Driving Concepts (16–18 karts every round, T4 and LO206 Cadet), Hayner Racing Team (up to 11, mostly 100cc Junior), Proper Form Motorsports (up to 12, Birel ART, the whole ladder), Phil Giebler Racing (5–7, Masters), Precision Karting, Croc Promotion USA, S Squared, Speed Factory, Casner Racing Development, Team KartNick, and Mike Manning Karting at the Willow Springs rounds. Fields ran from 59 (Chill Challenge) to 141 (the IKF Grand Nationals, where only 28 entries were from SoCal); 73% of the season’s entries came from Southern California, with Nevada and Arizona supplying most of the rest at Spring Mountain. Entry lists with team and chassis are public on RaceSelect, which is how we know. Every SoCal team is on our Teams page; how to pick one is in Field Notes.
Get on the Tri-C Discord
Tri-C lives on Discord, especially on race weekends. Getting into the Discord is really how you get into the series. That’s where the weekend schedule, run groups and last-minute changes get posted, plus what’s happening between events. It’s far more current than the website. Ask for an invite when you register. More on why.
Why you might not
- The website is thin. The real information is on Discord. RaceSelect is for signing up and live timing.
- Night rounds run very late for small kids.
- Spring Mountain means a four to five hour tow.

Live timing
Every series seems to use a different timing app. We’ve ended up with Speedhive, Alpha Racehub and RaceSelect all on the phone, and on race day we just ask around in the paddock where times are posted. Tri-C’s past results are on MyLaps Speedhive and Tri-C’s results page.
