Why join STORM?

Want more and better mountain bike trails in San Antonio? So do we. South Texas Off Road Mountain-Bikers (STORM) is your local all-volunteer mountain bike and trail advocacy 501(c)(3) nonprofit organization. We build new trails and improve existing ones. We build relationships with landowners and the City of San Antonio to increase access to trails. We host mountain bike races, and we hold group rides to get more people on mountain bikes, including specific rides and clinics for women and kids. We represent the mountain bike community in countless forums to protect the trails we have and advocate for new ones.

The more members STORM has, the more powerful our collective voice and the bigger and better we can grow the mountain bike scene in the San Antonio area. Now is an important time to join STORM and add your voice to the hundreds of other mountain bikers in the greater San Antonio region. The upcoming 2022 San Antonio bond provides many possibilities to get more trails and MTB facilities in an Antonio, but only if we make our voices heard. Decisions are being made now in City Council District offices for how to allocate these bond funds and STORM is communicating with City Council members to make sure the voices of the MTB community are heard.
