2025 Cardiff Half Marathon
One of the largest and most exciting road races in Europe, the Cardiff Half Marathon returns to the streets of Cardiff on Sunday 5 October in 2025.
A member of the SuperHalfs series and awarded an Elite Label by World Athletics, the flat, fast course passes all of the city’s most breathtaking scenery and iconic landmarks including Cardiff Castle, the Principality Stadium, Civic Centre and stunning Cardiff Bay. Join the thousands of other runners being cheered along the way by the crowds of spectators lining the streets.
General entries sold out at record pace, within just 12 hours of launching, but all hope is not lost if you want to run in 2025! You can still secure a space via our official charities and tour operators, or via a Business Challenge package.
