Cardiff Half Marathon

The Cardiff Half Marathon has grown into one of the largest road races in the United Kingdom. The first event took place back in 2003 and is now the UK’s second largest half marathon. The event is free to watch but you need to pay a registration fee to take part.

The 2012 event witnessed the introduction of a new course which encompassed Cardiff’s most iconic landmarks and was enthusiastically received by runners. The size of the field has dramatically expanded during the race’s history; from just under 1,500 runners in 2003 to 18,000 in 2012.

The race starts outside Cardiff Castle and runners then head down past Cardiff City Stadium on the way to Penarth. They take in the glorious Penarth Marina before crossing the barrage and heading to Cardiff Bay. Runners run right through the heart of the bay taking in the Norwegian Church and Wales Millennium Centre.

The course then heads towards the north of the city and runners will complete a loop of the beautiful Roath Park Lake before the grandstand finish in the heart of the city at the Civic Centre.

Event Times:

The race starts at 9am with the first runners finishing about one and a half hours later.


Advance tickets are not required.
