Judo Jujitsu Colayrac: judo and BJJ under one roof, run with OSS Academy

In Colayrac-Saint-Cirq, in the Lot-et-Garonne, a club founded in July 2025 pulled off what takes many years to build: more than 50 members in its first season, 20 sessions a week and already 29 competition medals. Judo Jujitsu Colayrac is an independent club running two disciplines under one roof, judo and Brazilian jiu-jitsu, on 100 m² of mats.

Behind that start there are two complementary head coaches, a clear project and an organisation that keeps up. It is also one of the clubs running their daily operation on OSS Academy: members, attendance, belts and communication all live on a single platform, for judo as much as for BJJ.

Two disciplines, one dojo

Judo Jujitsu Colayrac’s bet is right there in the club’s name: bringing judo and Brazilian jiu-jitsu together in one project rather than letting them coexist in silos. The week is built around 20 sessions, 12 BJJ classes and 8 judo classes, from children to adults.

What the team is proudest of is having created a club that unites people across two disciplines, in the service of the deeper values of martial arts. On the mats, that translates into a genuinely shared culture of both ground fighting and stand-up work, embodied by two coaches who each practise both disciplines.

Clément Herrero and Emma Duprat, two complementary head coaches

Leading the club is a duo whose backgrounds mirror each other.

• Clément Herrero, head coach for BJJ, is a purple belt under Yosuke Takagame and a judo black belt, 1st dan. In 2026 he became French BJJ champion with France Jujitsu.
• Emma Duprat, head coach for judo, is a judo black belt, 2nd dan, and a BJJ purple belt under Pierre-Yves Ferrer. She finished 3rd at the 2026 French championship (France Jujitsu).

Two grades, two specialities, one standard: each brings the discipline closest to their heart while practising the other one. That dual expertise is what gives the club its coherence, since students progress inside a single system rather than two schools placed side by side.

A first season already on the podium

For a club born in July 2025, the 2025/2026 record is remarkable: 15 competitions entered and 29 medals brought back to Colayrac-Saint-Cirq.

A few standout results:

• Anton Herrero, French Ne Waza U18 runner-up and 7th at the 2025 JJIF Worlds
• Clément Herrero, 2026 French BJJ champion (France Jujitsu)
• Emma Duprat, 3rd at the 2026 French championship (France Jujitsu)
• Frédéric Bergeron, 2025 CFJJB French champion (blue belt, Master)

From the kids collecting their certificates to the adults stepping onto national podiums, the club built a real competition culture in a single season.

How the club uses OSS Academy

Running a club is work enough. Running two in one, with members who sometimes practise both disciplines, can quickly turn into an administrative headache. That is where OSS Academy comes in.

With the app, Clément and Emma centralise the club’s entire life in a single platform:

• Members: one club roster, always current, available in a couple of clicks
• Attendance: the roll is taken at the start of class and each person’s tracking is automatic
• Belts: gradings and progressions recorded over time, for judo as well as for BJJ
• Communication: club news lands directly on members’ phones

The result is a club that professionalises without adding weight to the coaches’ days: less admin, more time on the mats.
