Unlimited Off-Road Racing

The Unlimited Off-Road Racing league was formed by The Martelli Brothers in 2023 after more than a decade of successful desert off-road race promotion, including The Mint 400, The UTV World Championship and The California 300. The league was formed to promote the sport of desert off-road racing, the off-road industry, and to expand the reach of off-road companies beyond the industry and into the homes of every off-road race fan, globally. Key attributes of the newly formed league include large racer car counts, competitive and challenging race courses, safe and family-friendly spectating areas, multiple days of racing and off-road festivities all located near major cities and markets that positively affect the off-road industry. The Martelli Brothers, owners of the motorsports powerhouse production group Mad Media have made it their mission to grow the league into a four race series that showcases the best off-road racers on the best courses in North America.
