I need a place

We don’t have charity places in the Principality Cardiff Half Marathon. If you would like to take part, you will need to purchase your own place though the event organisers. 

I already have my Own Place

If you have already received confirmation of your entry from the organisers, you can register for free. All we ask is that you raise what you can to support young people with cancer.

3 reasons to run for us

We could go on all day about why you should join our team, but we’ll keep it short.

  1. You’ll receive a free exclusive Teenage Cancer Trust running top kindly donated from our partners at MandM.
  2. You’ll have free support from our incredible training partner and expert fundraising team.
  3. Most importantly, you’ll be helping young people with cancer.

Why support Teenage Cancer Trust

A young person talking with a Teenage Cancer Trust nurse

We create world class cancer services for young people in the UK, providing life-changing care and support so young people don’t have to face cancer alone.

Every day, seven young people aged 13-24 hear the words “you have cancer”. They will each need specialised nursing care and support to get them through the toughest times they may have faced.

We’re the only UK charity dedicated to meeting this vital need. By choosing to run for Teenage Cancer Trust, you can help us to reach every young person facing cancer and make a huge difference.

So you know we’re the real deal, these are our registered charity details: 1062559 (England & Wales), SC039757 (Scotland).
