MSR GRASSROOTS OFF-ROAD SERIES

---

Grassroots Promotions is proud to announce the 2026 AMA Grassroots Off-Road Challenge.

Five weekends of Grand Prix style events for all ages and skill levels.  

What does Grassroots Off-Road Grand Prix consist of?   

Don’t call it a desert race.

· Each event will be based at our regions’ elite motocross facilities, Cache Valley MX, Bunker Hill, & Mesquite MX.

· The course will consist of the full motocross track, along with 4-6 miles of prepped and watered off-road course. The off-road sections will challenge you with sand whoops, tree sections, grass fields, and yes, the famous Cache Valley corn maze.

· Moto length ranges from 30-90 minutes depending on your skill level.   

· Pre-set race order: You know exactly what time you’ll be racing. 

· Fun for both motocross and off-road racers. 

The 2026 Grassroots Off-Road Challenge consists of 5 weekends of racing and 6 championship rounds.

The Dynamite Grand Prix will serve as a double header weekend. Saturday Rnd 3  & Sunday Rnd 4*. 

• Rounds 1, 2, and 3 make up the regular season.
• Rounds 4, 5, and 6 make up the Grassroots Off-Road Playoffs.
• All Playoff rounds award double championship points.

Whether you are chasing a championship, battling for a podium finish, or trying Grand Prix racing for the first time, the Grassroots Off-Road Challenge gives motocross and off-road riders a fun, competitive race format with something for everyone.
