Cardiff Half Marathon

Join the Hywel Dda Health Charities team in October 2026 and run like you’ve never run before in the flat, fast, iconic road race around Wales’ capital city!

About the Marathon

The Cardiff Half Marathon (opens in new tab) has grown into one of the largest and most exciting road races in the United Kingdom. It is now one of Europe’s biggest half marathons and is Wales’ largest mass participation and multi-charity fundraising event.

How do I enter?

We have a limited number of charity spaces. To apply for a space, please click here. We’ll be in touch if you have been successful.

If you are successful in securing a space, there is a £30 entry fee. You will receive a Hywel Dda Health Charities water bottle prior to the event plus support with your fundraising, and you will receive a charity T-shirt once your fundraising has reached £100.

After event completion, each entrant will be sent a certificate and medal.

Fundraising pledge

We ask that you pledge to raise a minimum of £300 in sponsorship for our charity. Please note that you can choose to support a specific hospital, ward, service or department OR you can choose to fundraise for general charitable purposes. Fundraising for general charitable purposes means that your funds will be spent where and when they are needed the most.

Have your own space? Why not fundraise for us?

If you have your own space at the Cardiff Half, you can still fundraise for your NHS charity.

You’ll receive a Hywel Dda Health Charities water bottle prior to the event and - once your fundraising has reached £100 - a charity T-shirt, plus a certificate and medal after the event. You’ll also receive all the help you need raise funds for your local NHS. For more information, please get in touch.

Thank you for your support - and enjoy the run!
