WSMTB Logo

BuDu Racing, LLC began promoting the West Side Mountain Bike Series in 2006 with just four events at South Seatac Park. The next year we added the Black Diamond Trails and kept adding locations after that. WSMTB has always been early season mountain bike series, mainly because of the BuDu event and timing schedule during the summer. 

There are currently no events scheduled in this category. Please check back soon as we are always adding new events.

If you have a suggestion for an event in your area, please let us know.
