Organized by Proving Grounds
The 31st Proving Grounds tournament brings submission-only no-gi grappling to Lakewood, WA on September 12, 2026, with divisions open to all skill levels.
Event Description
Proving Grounds XXXI is the latest edition of Washington State's longest-running submission-only no-gi grappling tournament, established in 2013 and run by KYS Promotions. True to its "no points, no excuses" philosophy, matches are decided purely by submission in a round-robin format designed to give every competitor more mat time and more chances to learn, rather than a single-elimination bracket that can end a competitor's day after one loss. This 31st edition takes place September 12, 2026 in Lakewood, Washington, open to grapplers of all experience levels who want straightforward, high-volume competition. Registration is handled through Smoothcomp — find the sign-up link on this listing to lock in your division before the event.
