Known for its legendary fast and flowy singletrack, supportive atmosphere, and all-level categories, the series has become a favorite for everyone from beginner riders to elite racers looking for high-energy cross-country competition. But what truly makes the 3CX series special is the people.
The 2026 3CX Summer MTB Series returns to Fort Ord National Monument with the BLM Blaze XC on May 31, bringing fast cross-country racing, flowing singletrack, and a welcoming grassroots mountain bike community to Northern California riders of all levels.
