Tilted Thunder is a Seattle based, all-female, banked track roller derby league. We are a 501(c)3 nonprofit organization run by a volunteer force of skaters and league members committed to promoting and raising awareness of women's roller derby, especially banked track roller derby. TTRB is comprised of strong, friendly, intelligent, enthusiastic women from all walks of life pursuing emotional growth and physical strength by challenging their perceived limits. As a league, we also wish to promote mental and physical empowerment, development of skills, loyalty on and off the track, individuality, and friendship - throughout the entire sport, both locally and nationally.


After much fundraising and hardwork, TTRB acquired a warehouse, track plans and materials and TTRB skaters, refs, and volunteers built a Kitten Traxx track in 2010. Our track design follows the same track plans of the other modern tracks in the United States: L.A. Derby Dolls, San Diego Derby Dolls, Deadly Rival Roller Derby, and Arizona Derby Dames. Other banked track leagues, such as TXRD Lonestar Rollergirls and Penn Jersey Roller Derby have older banked tracks built with a slightly different design.


The modern reincarnation of community-based, Do-It-Yourself banked track roller derby is only just beginning to experience the kind of growth that flat-track roller derby saw only a few years ago.

Not only are we the only modern banked track league in the Pacific Northwest, we are one of only a small handful of modern DIY banked track leagues in the country. Even though there are over 700 modern flat-track leagues in the United States, we are the 7th roller derby league to build a banked track in the nation. Even more unique, we are the only one of these banked-track leagues who is a 501(c)3 nonprofit organization!



In addition to our internal goals, Tilted Thunder Rail Birds strives to improve our community by volunteering for other community organizations. Volunteering our time to positively impact those around us is a core belief that we all hold. Please feel free to contact us if you wish to have us help out at your next event!


Tilted Thunder is committed to developing female amateur athletes for competition, and promoting their physical and mental strength and independent spirit.

Yes, roller derby has a strict set of rules. No, we do not use our elbows. On the banked track we follow RDCL Rules. However, when we are challenged to a flat track bout we skate under WFTDA Rules.
