Washington

The biggest indoor dirt bike series in the world: seventeen Saturday nights in NFL stadiums from Anaheim in January to the Salt Lake City finale in May. The 250SX class splits into East and West regions that meet only at the Showdown.

America's outdoor national series: eleven Saturdays of two-moto racing on the toughest tracks in the country, from Fox Raceway in California to the Ironman finale in Indiana. Feeds into the SuperMotocross playoffs.

The biggest amateur race in the world, and the one every American pro has ridden. Six days at Loretta Lynn's Ranch in Tennessee, 1,500+ riders across 36 classes, all of whom earned their spot through a nationwide qualifying process.

Seven-round amateur motocross series at Washougal Motocross Park, the natural-terrain Pacific Northwest track that has hosted the AMA Pro Motocross Washougal National for 40 years. All Classic 7 rounds are AMA-sanctioned and run by Washougal MX Park, LLC; riders who compete and finish 5 of 7 rounds qualify for the Series End Awards.

Grassroots family motocross points series, 'CMMX Series presented by Denny Menholt Chevrolet', 13 rounds across 7 weekends in central/western Montana plus one weekend in Spokane, WA; final round doubles as the Montana State Motocross Championship at Last Chance Raceway, Helena.

Grassroots amateur motocross race series at Pacific Raceways / MotoPacific in Kent, WA (greater Seattle area). The Fall MX Series runs three rounds; MotoPacific also runs a separate 'Friday Night MX Series' May-Aug each year.

Winter-season race series run entirely at Woodland MX Park in Woodland, WA, as the track's Sunday race program; a separate Saturday-run 'Modern Beginner, Vintage & Pit Bike Series' fills most of the same weekends. Woodland is a small, independently-run, family-operated facility (founded 1975, no listed sanctioning body), and its own downloadable flyer is a season behind. The 2026-27 season's 9 rounds are billed by date ('MX Cup Series: October 11' and so on) rather than by round number, and run in that order. Two other dates on the venue's calendar are open practice rather than racing: the Nov 7, 2026 'MX Cup Series Open Practice', and the Mar 27, 2027 '2026-27 Awards Ceremony & Open Practice' that closes the season.

A six-round Washington points series run by Team Tortoise Racing (established 1993; the NORCS series itself dates to 2014). Self-described as an off-road championship series, but every 2026 round is held at an established closed-course motocross park in a standard practice-plus-two-motos race-day format rather than a woods hare-scramble course.

Small 3-round traveling motocross series across Washington and Oregon.

AMA-affiliated 501(c)(3) nonprofit motocross points series uniting dealers, OEMs, riders and tracks across Washington and Oregon. Races at six tracks, five in WA (MotoWest MX in Port Orchard, OPMC MX, Woodland MX Park, Horn Rapids MX in Richland, Hannegan Speedway) and one in OR (Albany MX Park), over a roughly 14-round season, with the final rounds explicitly labeled the season finale.

A single-venue, single-day club series at Woodland MX Park (Woodland, WA). The promoter's own site labels it 'Vintage / Modern Beg / Pit Bikes MX Series'; elsewhere it is listed as the 'Modern Beginner, Vintage & Pit Bike Series'. It runs 8 numbered rounds on Saturdays through Woodland's 2026-27 winter season (one of the few PNW tracks that stays open through the rainy season), alternating weekends with the track's separate Woodland Winter MX Series, which races Sundays at the same venue. The promoter's own schedule page numbers the rounds 'RACE #1' through 'RACE #8'. High-point series awards are presented at a shared 2026-27 Awards Ceremony on March 27, 2027 alongside the Winter MX Series and Modern Beginner Series. The miss allowance is published two ways: the vintage-series rules page says 7 of 8 races are required, while the event listing says riders may miss up to two.
