2026 Denver Supercross – 450SX Main Event | Round 16

The 450SX Main Event at the 2026 Denver Supercross is the penultimate premier class race of the season — and at Empower Field at Mile High in Denver, Colorado, the championship arrives at one of its most decisive moments with everything still to play for heading into the final round.

Denver has always been a venue that demands something extra from the 450SX field. The altitude at Mile High pushes every rider and every machine to their physical limits, and a full night of competition at over 5,000 feet of elevation means that the main event is contested by a field that has already been tested harder than at any other round on the calendar. The riders who have managed those demands most effectively throughout the night are the ones who arrive at the main event gate ready to deliver a championship-level performance.

With only one round remaining after Denver, the 450SX Main Event at Mile High is a race where the title can be won, lost, or kept alive going into the final night of the season. Every position on the track translates directly into championship points, and the riders who can execute under that pressure — at altitude, on a worn and demanding track surface, in front of a packed Empower Field — are the ones who deserve to be in contention when it all comes down to the wire.

The 2026 450SX championship has delivered drama and unpredictability from the very first round. Denver is the penultimate chapter — and the main event at Mile High is where the story takes its final turn before Salt Lake City closes the book on the season.
