Barry O’Donovan

Barry O’Donovan’s academy takes jiu-jitsu into schools, rugby clubs and youth groups.

Biography

4 Honor’s history begins with Barry O’Donovan watching his daughter’s Massachusetts classes in 2017. After an early competition defeat, he trained with Hudson Lee and earned blue belt. Returning to Ireland meant choosing Cork journeys, quitting or starting locally. His brother’s hotel nightclub became a gym under disco lights. He taught children and friends, but Hudson’s visits could not provide daily coaching. Guilherme’s January 2023 arrival brought separate children’s levels and adult classes. The Southern Star’s February 2025 introduction identified O’Donovan as founder and named the coach as Guilherme Alencar. The academy describes an outreach program for schools, rugby clubs and youth groups. Its sessions combine jiu-jitsu with movement games and tasks that require people to work together. Falling, controlling contact and self-defense suited to the age group are listed subjects; the school offers to adapt sessions to each organization. That work reached Munster’s girls’ rugby squads at a two-day camp reported by the Southern Star in November 2025. Bantry Bay Adventures organized the camp, with 4 Honor seminars and Rosa Walsh among the coaches. O’Donovan, who coached rugby and jiu-jitsu, had also introduced jiu-jitsu to West Cork Warriors. He singled out learning to fall correctly as his priority. Hosting Munster fulfilled a personal hope.

    • The academy traces his 2017 Massachusetts start to his daughter’s classes and an early competition defeat, followed by training with Hudson Lee and reaching blue belt. Returning to Ireland forced a choice between Cork journeys, quitting or creating local training. His brother’s disused hotel nightclub became the gym, with mats beneath disco lights. He initially taught children and friends; Hudson’s occasional visits prompted a search for a resident coach. Guilherme arrived in January 2023, establishing separate children’s levels and adult classes.
