Cardiff Half Marathon


The CDF 10K was established by Welsh charity Kidney Wales in 1985.

In 2023, Run 4 Wales (R4W), Wales’ leading mass participation events company added the historic Cardiff 10K to its portfolio of world-class events. The revival of this iconic event gives thousands of runners the opportunity to take to the streets of the Welsh capital every autumn.

A series of Jr races give budding athletes and families the chance to absorb the race day atmosphere, with fancy dress very much encouraged.
