SOS × Biltwell 100 – Your First Step Into Desert Racing
The Biltwell 100 is one of the most iconic and accessible desert races in California. Taking place over a weekend in April, the event brings together hundreds of riders across all skill levels for a uniquely inclusive racing experience.
This isn’t a pro-only race - “Good Times, Not Lap Times”
The Biltwell 100 is designed for regular riders — people who ride adventure bikes, dual sports, dirt bikes, and even pit bikes — and want to experience desert racing in a supportive, community-driven environment.
With a 25-mile lap format, riders race multiple laps of the same course, making it easier to learn the terrain, safer for first-time racers, and incredibly fun for spectators and pit crews alike.
Why it’s perfect for non-racers:
Friendly, welcoming atmosphere
Multiple classes and skill levels
Ride your own pace
Race anything from ADV bikes to pit bikes
Big focus on fun, not just results
⚠️ Important: Registration for the Biltwell 100 historically sells out within hours of opening.
