what we do
Seattle premier Gi and No Gi grappling event is back. The only tournament located right in the heart of Seattle. With a professional video production team on staff, you'll have easy access to all your matches after the event. Join the NW grappling community in welcoming back GSUBX.
Our referees are empowered and instructed to stop a match when they feel a submission is fully locked in. Please make sure to refer to gsubx.com/rules for all of the legal/illegal holds based on your division.
We will have EMT's on site. While we have a fantastic safety record, we highly encourage all competitors to make sure you have valid insurance. Jiu jitsu is a contact sport, and injury is always a possibly. Take whatever steps necessary to protect yourself during and after the event.
There will be a lot of competitors and many matches. Don't let pride jeopardize your ability to compete in upcoming matches.
