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

Join our Cardiff Half Marathon team and join 18,000 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.

Our supporters fund over half of the cancer research undertaken in the UK – collectively we are saving more lives every day.
