Oysho Cardiff Half Marathon

Oysho Cardiff Half Marathon 2026 takes place in Cardiff, Wales, on 4 October 2026. The event is part of the SuperHalfs series and is one of the largest mass-participation half marathons in Europe.

The course starts outside Cardiff Castle and finishes at the Civic Centre, taking runners through a route that includes the Principality Stadium area, Penarth Marina, Cardiff Bay, the Norwegian Church, the Senedd, Wales Millennium Centre and Roath Park Lake. This gives the race a clear city-tour identity as well as a fast road-running format.

The event suits runners who want a major autumn half marathon with strong crowd support, charity participation and a recognisable capital-city route. It is a good SuperHalfs option for both first-time half marathon runners and experienced runners looking for a large, well-organised event.
