The 3CX (CCCX) MTB Race Series is the Bay Area’s biggest and longest-running MTB race series, now entering its 29th year of full-gas racing at Fort Ord.
3CX is known for its fast, flowy courses, smooth rhythm, and friendly racing atmosphere. Each round delivers a perfect blend of speed, endurance, and fun — open to all ages and skill levels, from first-timers to elite XC racers.
2026 Race Dates:
January 4 · January 18 · February 1 · February 15 · March 29
All races take place at Fort Ord, National Monument, featuring the same fast, rolling terrain riders have loved since 1997.
Team Competition (New for 2026). Bring your crew and go for team glory! Teams earn points based on rider results across the series. Schools, clubs, and local groups are all welcome.
Race Packs – Save Big. Race Packs are blocks of fully transferable registrations valid for any 3CX race. Use them however you like — a 5-Pack can cover 5 racers at one event or one racer at five different rounds.
Whether you’re chasing the podium or just out for a fast lap and good vibes, 3CX delivers pure, full-gas mountain bike racing — the way it’s meant to be.
