The Cardiff Half Marathon Course

The Cardiff University/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 the 10th Anniversary was celebrated in 2012.

The event is not only the UK’s second largest half marathon, it is Wales’ largest road race and Wales’ largest multi-charity fundraising event.

The race is sponsored by Cardiff University and supported by strategic partners Cardiff Council, Vale of Glamorgan Council and Welsh Athletics.

The 2012 event witnessed the introduction of a new course which encompassed Cardiff’s most iconic landmarks and was enthusastically recieved by runners.

The size of the field has dramatically expanded during the race’s history; from just under 1,500 runners in 2003 to 22,000 in 2016.

The course played host to the IAAF/Cardiff University World Half Marathon Championships in March 2016, where Britain’s Mo Farah won a bronze medal and Kenya’s Geoffrey Kamworor won back-to-back World Half Marathon titles. In the women’s race Peres Jepchirchir led a Kenyan clean sweep in the women’s event.

The Cardiff University/Cardiff Half Marathon is now host to the Welsh Half Marathon Championships, recognising Wales’s best athletes. 2014’s winners were Emma Wookey (Lliswerry Runners) with a time of 75.56, whilst Ieuan Thomas (Cardiff AAC) secured top spot with a time of 65.40.  The event attracts the world’s top runners.



The route takes runners past the capital’s most iconic landmarks with beautiful scenery and historic buildings. The predominately flat and fast course makes it ideal for beginners and elites.

The race starts outside Cardiff Castle and runners then head down past the Principality and Cardiff City Stadiums 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.

The wheelchair race will start at 9:50am. Elite, white, green and red pens will start at 10:00am and yellow and blue pens will start at 10:10am. Check out the interactive route map above to see the route in more detail.

The course will be policed and marshalled throughout.

EN-ROUTE TOILETS: There are toilets not only at the start of the race and in the Event Village, but also within the first mile of the race and around the course at all drink stations. If you need the toilet, please use the toilets.
