Bulgaria's capital is also its main hub for jiu-jitsu competition, and BJJ турнири в София come up on the calendar more than anywhere else in the country. Sofia has hosted dozens of BJJ and grappling events since 2023, and several of them have taken place at the same venue on Rozhen 23, so regular competitors quickly get to know the walk to the mats.
Grappling Industries is the most familiar international name in the city, running editions under both the Grappling Industries Sofia and Grappling Industries Bulgaria banners. The SJJIFBF Sofia Spring Open Gi & No-Gi is a recurring spring fixture with a matching Winter Open, and Sofia has also hosted the ADCC Balkan Open Championships, the FUJI European Open Bulgaria and the Sofia Open Winter BJJ. Grappling Industries Eastern Europe and the Lubomir Guedjev academy are among the organisers behind events in the city.
Gi and No-Gi are split evenly in Sofia, about a quarter of events include kids divisions and roughly two in five offer an absolute. Grappling Industries rules are the most common, and their round robin brackets mean a white belt gets several matches even if first comp nerves take over in the opener. December and March are the busiest months, followed by April, January and November.
