Mark World Cancer Day on 4th February 2020 by running 12k for the 12 children and young people diagnosed with cancer in the UK every day.

Each day, 12 young lives are put on hold to deal with long hospital stays, endless tests and intense treatment. No child should have to go through this. Together we can make a difference.

Whether you’re training for a marathon or just love running, join Children with Cancer UK’s 12for12 club and run 12k on World Cancer Day (Tuesday 4th February)*.

*Run, jog or walk. You can complete the challenge any day that week (it doesn’t have to be on World Cancer Day).

How do I join?

Taking part is easy. You can do your run anywhere, from your favourite park to your local gym.

Please note that official registration has now closed. However, if you’d still like to take part on your own, simply donate £12 via our main donation page and do the run whenever you can!
