Sun, sea, and sand provide the backdrop to the Barry Island 10K – which brings a summertime festival of running to the popular seaside resort.

Established in 2018, it has quickly become a firm favourite with runners – renowned for it’s varied and scenic route, unbeatable crowd support and feel-good atmosphere. It’s delivered by Run 4 Wales, the team behind events including the Cardiff Half Marathon & ABP Newport Marathon Festival and forms part of the popular Run 4 Wales 10K Series.

The 10K race takes place on fully closed roads with a rewarding route showcasing all of the town’s most scenic seaside spots and recognisable landmarks – including Whitmore Bay, the Knapp, Romilly Park and Watch House Bay.

A host of Junior Races including Fun Run, Toddler Dash and competitive Future Challengers event take place along the promenade – giving budding athletes and families a chance to get in on the action.

Races start and finish at the iconic Whitmore Bay, which also hosts an exciting Event Village with live music, entertainment, stands and tasty street food. Relax on a deck chair post-run or enjoy an optional (but very much encouraged) dip in the sea on Barry’s golden sandy beach.

New for 2026 – the Gŵyl Fach y Fro Welsh language, arts and culture festival, taking place on Saturday 16 May – has been extended into a full weekend, alongside the Barry Island 10K on Sunday 17 May.
