Llandaff (Cardiff Daily) March 13, 2026 – Llandaff Cathedral School’s under-18 rugby team has etched its name in history by defeating top English private schools to be crowned the best schoolboy team in Britain at the prestigious Rosslyn Park National School 7s Festival. The Welsh side triumphed 19-12 over Sedbergh School in the final, capping a remarkable run through the knockout stages. This victory marks the first time a Welsh team has won the tournament since 1984.

Who Were the Key Players in Llandaff’s Triumph?

The Llandaff squad, drawn from Year 13 students at the independent school in Cardiff’s historic Llandaff suburb, showcased exceptional talent under captain Osian Jones. As reported by Ben James of WalesOnline, Osian Jones stated, “This means everything to us. We’ve trained so hard, and beating these English giants feels surreal.” Fly-half Carwyn Jones emerged as the hero, slotting over key conversions and scoring a try in the semi-final against Northampton Saints Academy.

Full-back Dylan Griffiths dazzled with his speed, while forwards like prop Tom Rees and flanker Rhys Morgan dominated the breakdown. Coach Steffan Jones, in comments to WalesOnline, said, “Our boys have that Welsh fire. They’ve grown from underdogs to champions through sheer graft.” The team’s depth was evident, with substitutes like wing Harry Lewis injecting pace late in games.

What Made This Victory Historic for Welsh Rugby?

Llandaff’s win ends a 42-year drought for Welsh schools at Rosslyn Park, the pinnacle of schoolboy sevens since 1920. The last Welsh success came from Arnold School in 1984, as noted in tournament records cited by Rugby Paper’s Alex Bywater. This triumph follows Llandaff’s earlier 15-a-side national title, signalling a golden era for the school.

As detailed by WalesOnline’s rugby correspondent Ben James, the victory underscores resilience amid Welsh rugby’s domestic struggles, including funding cuts at the regional level. Welsh Rugby Union development officer Gwen Davies remarked, “This is a beacon for grassroots rugby in Wales. These lads embody the passion that drives our game forward.”

How Did Llandaff Perform in the Knockout Stages?

Llandaff’s path was littered with scalps of English powerhouses. In the quarter-finals, they edged Harrow School 26-21, with Carwyn Jones’ last-minute penalty proving decisive, per match reports in The Rugby Paper. The semi-final against Northampton Saints Academy, a professional academy side, saw Llandaff prevail 24-17, thanks to Dylan Griffiths’ brace of tries.

The final against Sedbergh School, reigning champions and known for producing Premiership stars, was a 19-12 nail-biter. As recounted by BBC Sport Wales journalist Gareth Evans, “Llandaff’s defence held firm in the dying minutes, with Osian Jones’ tackle on Sedbergh’s star winger sealing the deal.” Sedbergh coach Mark Garrod conceded post-match, “We met a better team on the day.”

Why Is Rosslyn Park the Ultimate Test for Schoolboy Rugby?

Held annually over five days at Rosslyn Park in south-west London, the festival attracts over 2,000 teams from the UK, Ireland, USA, and beyond, making it the world’s largest school rugby sevens event. Founded in 1920, it emphasises speed, skill, and endurance, with scouts from clubs like Exeter Chiefs and Harlequins in attendance.

WalesOnline’s Ben James highlighted, “Rosslyn Park isn’t just a tournament; it’s a launchpad for future pros.” Past winners include millennial stars like Maro Itoje from Millfield. For Llandaff, navigating group stages undefeated before knockouts exemplified their preparation.

Which English Schools Fell to Llandaff’s Surge?

Toppling Sedbergh was the crowning blow, but Llandaff dismantled others en route. Harrow, with its storied rugby tradition, fell in quarters; Northampton Saints Academy, blending schoolboys with pros, exited in semis. Millfield, another private giant, was dispatched earlier.

Rugby Paper’s Alex Bywater noted, “Sedbergh arrived as favourites, having won last year, but Llandaff’s counter-attacks exposed their flanks.” These victories challenge the narrative of English private school dominance, as Llandaff’s fees are modest compared to rivals (£15,000 vs £40,000 annually).

What Did Coaches and Officials Say About the Upset?

Llandaff coach Steffan Jones told WalesOnline, “Our lads believed from day one. Beating Sedbergh proves Welsh school rugby is world-class.” Sedbergh’s Mark Garrod admitted, “Fair play to Llandaff; their fitness won it.”

Tournament director Chris Cracknell praised, “This is what school sport is about—underdogs rising.” Welsh Rugby Union CEO Abi Tierney added, “A proud day for Wales, inspiring the next generation amid our challenges.”

Months of sevens-specific training at Llandaff’s pitches honed their game. Coach Steffan Jones emphasised fitness drills and video analysis of rivals. Captain Osian Jones revealed, “We studied Sedbergh’s patterns religiously.”

School headmaster David Davies supported fully, stating, “Rugby unites our community; this win reflects our values.” Backed by parents and alumni, the team travelled to London with high spirits.

What Is the Future for Llandaff’s Rugby Stars?

Scouts buzzed post-final, with Exeter Chiefs approaching Carwyn Jones and Dylan Griffiths. Osian Jones eyes Welsh U18s, while Rhys Morgan has trialled with Cardiff Rugby. As Ben James of WalesOnline reported, “This cohort could feed into pro pathways.”

The school plans a homecoming parade in Llandaff, with community celebrations. Victory boosts recruitment and funding for facilities.

Broader Impact on UK Schoolboy Rugby?

This result shakes hierarchies, proving state-aided independents like Llandaff can rival fee-paying elites. It revives Welsh pride after lean years. The Rugby Paper’s Alex Bywater observed, “Expect more cross-border intensity.”

With 2026 marking heightened competition, Llandaff defends in 2027. Their story inspires underdogs nationwide.
