Cardiff Half Marathon 2026

The route takes runners past the capital’s most iconic landmarks with beautiful scenery and historic buildings.  It starts outside Cardiff Castle, goes past the Principality and Cardiff City Stadiums, heads to Cardiff Bay, round Roath Park Lake before the grandstand finish in the heart of the city at the Civic Centre.
