Cardiff Half Marathon

Signed up to run for charity and can no longer take part?

The money raised by runners at the Cardiff Half Marathon helps fund essential research, critical services and awareness building that makes a significant difference to a whole host of good causes.

If you can no longer take part due to illness, injury, or other personal circumstance, it’s really important that you contact your charity to let them know!

You shouldn’t feel any shame (charities understand that sometimes, life gets in the way) – and by getting in touch with your charity, you’re helping to ensure they have the opportunity to make use of your space by offering it to another potential fundraiser.

Likewise, if you have taken a space without intending to fundraise (because general entries have sold out) or can no longer fundraise for any reason – passing your space back really will make a difference.

You should be able to find your charities contact details in any of the e-mails you have received from them. Alternatively, charity contact details can be found here on our ‘choose a charity’ page.

Where does your fundraising go?

  • In the 2025 Cardiff Half, #TeamNSPCC collectively raised over £200,000, which could help to keep Childline open for 5 days. Childline is a life-changing NSPCC service. It gives children and young people a voice when they feel no one else is listening.
  • Based on the 74% of counselling sessions where the nation was known, we can estimate that around 4,400 counselling sessions were delivered, to children living in Wales in 2024/25. This wouldn’t be possible without our volunteer counsellors across the UK including those in Cardiff and Prestatyn – who give their time to be there for children.

  • Every misused space means that we lose a potential fundraising income of £250. This money would be used to help with vital services and research to provide help and hope to those living with dementia.
  • £30 can support Companion Calls, a vital service to reduce isolation. A friendly chat with a Companion Call volunteer keeps loneliness at bay.
  • £50 people can tell their story, their way, through Dementia Voice. Whether this is through campaigning work, speaking at events, or sharing their experiences in the media, this platform means people have a better understanding of life with dementia, from those who experience it every day.

  • We set the minimum fundraising target at £250 to ensure we’re able to cover the costs of delivering Cardiff Half Marathon as well as putting enough back into our vital services to support those living with a mental health problem. By not reaching the target, this means a loss for the charity. Your £250 could:
  • help us fight for mental health. Because this is a mental health crisis, and we’re needed on the frontline now more than ever.
  • help our Infoline advisors pick up the phone to 25 people with nowhere else to turn. Where they can find information about mental health problems, questions about treatment options and signposting to services.
  • help make sure 20 people with nowhere to turn can find a voice at the end of the phone on one of our helplines.

  • If runners are able to hit their minimum fundraising target for Cancer Research Wales, they’ll then help the below:
  • The money from non-fundraisers could have paid for 7 ThinkCancer! workshops, providing important training to GP practices covering tens of thousands of Welsh people.
  • The money from non-fundraisers could have paid for 3 patients to take part in our BiCCC clinical trial, which aims to prevent bowel cancer relapse after surgery.
