The Clash European Combat Sports Festival 2026 - MMA, Muay Thai, K-1 - FREE ENTRY

20–24 October 2026 · Unibet Arena, Tallinn, Estonia

Combat sports under amateur rules, all under one roof. For five days, Unibet Arena becomes the home of European amateur fighting: MMA, K-1 and Muay Thai (with a fourth discipline to be announced), brackets from youth to senior, athletes from 12 countries, and a festival built around the fighters, not just the fights.

Participation is 100% free. No registration fee, no mat fee, no weigh-in fee. The Clash is a non-profit event co-funded by the European Union through Erasmus+ Sport, because money should not decide who gets to compete.

More than a competition:

Compete. Full brackets in MMA, K-1 and Muay Thai (a fourth discipline to be announced) under IMMAF, WAKO and IFMA amateur rulesets, with a free professional live broadcast of every match on YouTube @TheClashBaltic.

Fight for the belt. Weight-class winners take home the Clash Champion's Belt: serialised, discipline-specific, yours to keep, and earned in the bracket, never handed out.

Learn. Free educational seminars all week: nutrition and recovery, mental health, training methodology, personal branding, coach development, judge certification and EU funding know-how for clubs. Master Classes from Glory Kickboxing and UFC fighters.

Get supported. The Erasmus+-funded Supported Athlete Programme helps athletes who could not otherwise afford to compete: selected athletes receive support towards travel or accommodation costs.

Get certified. Participants receive a Europass certificate recognising what they took part in and learned.

Festival week: Tue 20 Oct arrival + accreditation + welcome reception Wed 21 Oct qualifiers Thu 22 Oct semi-finals Fri 23 Oct finals + belt ceremonies Sat 24 Oct closing seminars + departures.
