Important event update

Due to the coronavirus (COVID-19) outbreak, the event organiser has postponed the 2020 Cardiff Half Marathon for the safety and wellbeing of all participants and spectators. It will now take place on 28 March 2021. If you have a 2020 charity place with us, we can confirm that your place is still valid and the event organiser will be in touch with further details.

If you can no longer make the new date and would like a refund, you will need to let us know by 22 July 2020. You can do this by emailing us at supporter.services@cancer.org.uk or calling 0300 123 5461.

Run through the heart of Cardiff and experience Wales’ largest road race.

Join our Cardiff Half Marathon team and 27,000 others in a race through the Welsh capital. The Cardiff Half Marathon has grown into one of the largest road races in the UK, taking you through the beautiful scenery and historic buildings of the city centre.

The route will take you past some of the Welsh capital's most iconic landmarks, with stunning scenery and beautiful buildings. Along the way you will pass the glorious Penarth Marina before crossing the barrage and heading to Cardiff Bay, where you will run right through the heart of the bay taking in the Norwegian Church and the Wales Millenium Centre. 

The flat roads along this course make this the perfect race for experienced and novice runners alike.
