Cardiff Half Marathon

Each year, event organisers Run 4 Wales (R4W) donate 100 free places in the race to people who can use them as a vehicle to improve their health and wellbeing and support them through their journey to the start line.

If you’re a community or non-profit organisation that has links to a group that could benefit, please contact [email protected].


In 2023, for our twentieth anniversary, we celebrated Cardiff and what makes the Welsh capital one of the most welcoming places in the UK: the diversity of its people.

We reached out to multiple community groups in Cardiff and Wales from various backgrounds and with different stories. Everyone in the Clwb 100 was united by one common goal, to reach the Principality Cardiff Half Marathon finish line and overcome hurdles that not every runner is required to overcome. We’d like to give our thanks to Pride Cymru, Grange Pavilion Youth Forum, Tiger Bay Boxing Club, TigerBay Football Club, Foundation 4 Sports Coaching, Oasis and others for their help in the recruitment of the 2023 Clwb 100!
