The curtain has officially closed on the 2026 Colorado Supercross season, and the RMRA Supercross Series saved one of its most interesting venues for last. On October 17, Colorado National Speedway played host to the season finale, with Black Diamond Promotions transforming the historic speedway’s infield into a Supercross circuit.
The event also marked our first time back covering a race in Colorado since making the move to Texas five years ago, and what a venue to return to. Having covered races at venues all across Colorado over the years, we can confidently say this was one of the more unique settings we’ve experienced. Throw in some picture-perfect fall weather and a track layout that offered something a little different from the usual arena-style Supercross, and the stage was set for a great final round.
With championships on the line and over 400 entries signed up, the final round delivered on all cylinders. There were some rad battles, plenty of great racing, and a handful of storylines that’ll stick with the Colorado crowd until next season. Let’s get into a few of the battles and performances that stood out.
450 C
In the 450 C class, Cobee Serak, Mason Green, and Elijah Gordy finished first, second, and third in their heat race, setting themselves up with some favorable gate picks for the main event. When the gate dropped for the main, Serak led the charge into the first turn, with Green and Gordy right behind him in second and third. Serak continued to lead the way, but by the second lap, Green was beginning to find his rhythm and chip away at the gap. Meanwhile, a little farther back, Austin Perry and Josh Kish were having a battle of their own for fourth and fifth.
By lap four, Green had worked his way to within roughly a second of Serak, setting the stage for what looked like a good battle for the lead. Unfortunately, just as things were getting interesting, Green went down hard in the main rhythm section, bringing his charge toward the front to an abrupt end.
From there, Serak went on to take the win, with Gordy moving into second and Kish rounding out the podium in third.
Elijah Gordy was a regular fixture on the podium this season, missing out just once. His consistency paid off with a second-place finish in the final championship standings.

UNDEAFETED
Jax Randall
First round, last round, and everything in between. Jax Randall made winning a habit throughout the 2026 Supercross season, arriving at the championship finale with a perfect record and looking to finish the year the same way he started it.
And that’s exactly what he did. Randall swept all three classes he entered, taking wins in 50cc 7–8, 50cc 4–8, and Mini-E, capping off a remarkable season with 18 main event victories to his name.
Monroe Beniamino
Randall wasn’t the only rider putting together a perfect season. The #60 of Monroe Beniamino had a pretty impressive year of her own. The Colorado Springs native went undefeated in the Girls Jr. 9–11 class, picking up a win at every round of the series.
The finale at Colorado National Speedway was no different. Beniamino led every lap of the main event, eventually crossing the finish line more than a minute ahead of the rest of the field to put the finishing touches on an undefeated season.
2-Stroke B/C 14+
This class may not have drawn the biggest turnout, but it produced one of the better battles of the morning program between Ayden Calvillo and Ryder Sharp.
Things got interesting right off the start as the two charged into the first corner. Sharp sent it in hard, nearly taking Calvillo off the track before they had even entered the first section.
Calvillo managed to stay upright, while Sharp opened up roughly a second-and-a-half advantage as the opening lap unfolded.
It didn’t take Calvillo long to erase that gap, though. From there, the two went at it for nearly the entire race, trading blows in what felt like every corner.
In the final corner, Calvillo made his move, while things went bad for Sharp when he went down on the final lap, nearly allowing third-place Ezekiel Kibler to sneak by.
Calvillo went on to take the win and, more importantly, claim the 2-Stroke B/C championship.
Open Mini 85cc 9-12
Just four points separated Niko Silva and Wyatt Fullerton heading into the Open Mini 85cc 9–12 championship finale, and for the first four laps, it looked like the title fight was going to come down to the wire.
Fullerton grabbed the early lead, but Silva was right on his heels, never letting the gap grow beyond half a second.
The two remained locked together through the opening four laps before things took a turn on the final lap when the championship rivals collided.
The incident opened the door for Ryan Smith, who had been running third, to take over the lead and grab the main event victory. Kayden Kearns moved into second, while Silva recovered to finish third. Fullerton, meanwhile, dropped to sixth after leading nearly the entire race.
Despite the last-lap drama, Silva’s third-place finish was enough to secure the Open Mini 85cc 9–12 championship. Smith’s victory moved him into second in the final points standings, while Fullerton slipped from second to third overall. A tough way to end the season for Fullerton, who had been just one lap away from winning the finale.

Super Mini 12-15
If Massa’s performance earlier in the day in the 85cc 12–15 class wasn’t impressive enough, he was back at it again in Supermini. While there was plenty of shuffling going on throughout the field, the Arvada, Colorado native seemed perfectly content running his own race out front. Massa grabbed the early lead and never looked back, clicking off consistent lap times while the rest of the field had their hands full behind him.
Jasper Jenkins was one of those riders on the move, going from fourth to second by lap two. Chase Brown had an even bigger hill to climb, running sixth on the opening lap before working his way onto the podium by lap three.
And while the top three had things pretty well sorted out, there was still some movement farther back. Logan Quinn slipped from third to fifth before recovering fourth on the final lap, while Nash Duncan put together a solid charge of his own, climbing from ninth on the opening lap to fifth by the checkered flag.
When it was all said and done, Massa took the win by just over eight seconds, with Jenkins and Brown rounding out the podium.
A Three-Way Fight for the Micro Shaft Title
Just six points separated the top three riders in the Micro Shaft championship heading into Colorado National Speedway.
Ripley Reader had the advantage, but Wade Koschel and Revin Reader were both close enough to make things interesting. And let’s be real, when you’re talking about a class full of kids who were learning to walk not all that long ago, just about anything can happen.
Reader and Koschel took the top two spots in their heat race, setting themselves up nicely for the main event. In the end, Reader wasn’t about to let the championship slip away, taking the win and wrapping up the title, with Koschel finishing runner-up.
250 B
Mason Brown and Travis Head established themselves at the front of the 250 B field early, leaving the battle for the final podium position to Trevor Frans and Luke Carns.
Frans held the advantage through the opening laps, but Carns continued to apply pressure, gradually closing the distance as the race progressed.
On lap four, Carns made the pass for third and managed to hold the position through the finish.
The podium result was enough to cap off his season with the 250 B Supercross championship, making the late race charge all the more meaningful.

REMARKABLE SEASONS
The Pros
450 A Goes Down to the Wire
The 450 A class delivered some of the best racing of the evening, and it didn’t take long for things to get interesting. Jorge Rubalcava grabbed the holeshot, with Hunter Schlosser, Cheyenne Harmon, Kaden Lewis, and Jace Hinrichs right behind him.
By lap two, Harmon had worked his way past Schlosser, and before long, both riders made their way around Rubalcava to take over the top two positions.
From there, it was an all-out battle between Harmon and Schlosser, with the two swapping positions multiple times throughout the race. Schlosser managed to take control on lap seven and held the lead heading into the white flag, but Harmon wasn’t about to let him have it that easily.
Keeping the gap close, Harmon made one final push on the last lap, reclaiming the lead and taking it home to the finish.
250 A
Carter Malcolm had the lead pretty well handled in this one, grabbing the top spot early and checking out from the rest of the field.
Behind him, however, Jace Hinrichs and Ryan Boutilier had a championship to fight over, and neither was willing to give an inch.
Boutilier held second through the opening five laps, but Hinrichs was all over him. The two went at it for nearly every inch of the track, with less than a second separating them through much of the opening half.
By lap six, Hinrichs finally found his way around Boutilier and managed to build a little breathing room. Malcolm continued clicking off consistent laps out front, eventually taking the win by nearly 14 seconds.
Hinrichs crossed the line in second, doing enough to secure the 250 A Supercross championship, while Boutilier rounded out the podium in third after one heck of a battle between the two title contenders.
65cc 7-9
Kayden Kearns had been the rider to beat in the 65cc 7–9 class all season long. Heading into the finale, he hadn’t lost a single main event and looked to have the championship pretty well wrapped up. But when the gate dropped at Colorado National Speedway, it was Ryker Fitch who took control of the race. Fitch began checking out from the field, while Kearns settled comfortably into second. Through the opening three laps, the two had the top spots pretty well handled, and with Kearns only needing to maintain his position to secure the title, everything appeared to be going according to plan.
Then came lap four. Kearns’ bike unexpectedly gave up on him, forcing him to push it toward the finish as both a podium finish and his championship hopes slipped away. Jax Radmall moved into second, Blake English inherited third, and Fitch went on to take a commanding victory by nearly 40 seconds.
The mechanical failure ultimately cost Kearns more than just a podium finish. Blake English, who had finished inside the top five at every round, capitalized on the opportunity to claim the 65cc 7–9 championship. A tough ending for Kearns, but a well earned title for English, whose consistency paid off when it mattered most.

That’s a Wrap, Colorado
And just like that, another Colorado Supercross season is in the books. Colorado National Speedway turned out to be a pretty cool place to wrap things up, with some great racing, close championship battles, and a venue unlike anything we’ve covered in the state before.
Big credit to Black Diamond Promotions for pulling off an event like this and continuing to support amateur Supercross in Colorado. It’s been a while since we’ve made it back to cover a race, but this trip reminded us just how much we enjoy the Colorado racing scene. Hopefully, we’ll be back for more soon.
