Get ready for an adrenaline-fueled showdown—the 2026 Arlington Supercross 250SX East Opener is here, and it’s packed with drama, surprises, and high-stakes racing! But here’s where it gets controversial: With the absence of two-time champion Tom Vialle, the field is wide open, and the question on everyone’s mind is—who will rise to claim the throne? And this is the part most people miss: the track layout at AT&T Stadium in Arlington, Texas, eerily resembles last year’s Detroit SX course, which delivered some of the most thrilling races of the season. Will history repeat itself tonight? Let’s dive in.
Welcome to the Racer X Race Day Feed, your go-to source for live updates, results, and behind-the-scenes action straight from the heart of AT&T Stadium.

Today marks the kickoff of the 250SX East Division season, and the excitement is palpable. While the weather outside is sunny with a high of 61°F, the real heat is indoors as we enter the seventh round of the 17-round Monster Energy AMA Supercross Championship. This isn’t just any race—it’s a battle for supremacy in one of the most competitive divisions in motorsports.
Here’s the twist: After four consecutive years of Triple Crown races in Arlington (2022–2025), this year’s event reverts to a standard format. What does that mean? Expect a more traditional, yet no less intense, race day. The 450SX championship remains a nail-biter, with Hunter Lawrence leading the points, while the 250SX East Division introduces a fresh crop of riders hungry for glory. Defending 250SX Champion Jo Shimoda stands out with his distinctive purple background and yellow #30, but he’s far from the only contender.
Bold prediction: With Vialle’s departure, the door is open for a new champion. Nate Thrasher leads the pack with six wins, followed by Seth Hammaker (three wins) and Cole Davies and Jo Shimoda (two wins each). But here’s the kicker—this field is stacked with talent, making it anyone’s game. Who do you think will take the first main event win? Let us know in the comments!
Controversial absence alert: Ty Masterpool, a fan favorite, won’t be racing today due to testing issues. His Instagram post hinted at a return next weekend, but his absence leaves a noticeable gap in the lineup. Check out the full injury report here for more details.
The track walk begins at 10 a.m. CT, with bikes hitting the course at 11:30 a.m. CT (12:30 p.m. ET). The schedule is packed, starting with 250SX sessions followed by the 450SX groups. Here’s a quick rundown of today’s events (all times local, Central Time):
