What is EFA Championship

EFA Championship (Elite Fighting Arena) is a Bulgarian combat-sports promotion based in Sofia, organized by Elite Fighting Ltd and co-founded by Antonio Grigorov.

This is where elite fighters from Bulgaria and around the world meet in spectacular Muay Thai and kickboxing battles - including 4 oz-glove bouts.

The promotion's first edition took place on 21 March 2026 at the Tenta Event Center in Sofia: Martin Koprivlenski became the first EFA champion and Teodora Kirilova closed her career with a win. EFA's mission is to build a world-class stage for fighters and combat-sports fans in Bulgaria.
