We are a group of riders, racers, coaches and volunteers who love mountain biking.

MTSIMTB is a non-profit organization run by volunteers.

Our season runs from March - September. We typically have practices on Friday as a standard.  Practices are optional and we will have specialty practices and events throughout the season. 

We encourage all our riders to try a mountain bike race, and usually we have athletes at all the Washington Student Cycling League Cross Country Races, the NW Cup DH Races and the CDC Youth Enduro Races.
