Jason Thomas previewed the track ahead of Round 12 of the Monster Energy AMA Supercross Championship, saying the layout and soil conditions at The Dome at America’s Center in St. Louis could be pivotal for the championship. Round 12 is scheduled for April 4, 2026, and the timing late in the season — combined with a familiar, rider-preferred St. Louis layout — was framed as having potential to influence the title race.

The series has returned to St. Louis after last visiting for the SMX Playoff round in September, and organizers and riders brought recent experience with the venue. Many riders noted they enjoy the St. Louis soil because it tends to be more predictable than the surface they encountered in Detroit, a characteristic Thomas highlighted in his track-focused preview of the impending showdown.

Supercross Live released a track-map video and images that take viewers on a lap around the St. Louis layout, giving fans visual context and offering competitors an early look at the lines, rhythm sections and overall flow. The layout preview was presented both as a promotional tool for Round 12 and as a practical resource for teams planning race-day strategy, helping attendees and remote viewers understand the stadium setup and the jump and turn sequences. Organizers and crews are positioned to use the video and images to prepare riders for the specific challenges of the St. Louis course ahead of the April 4 event.
