Hi there,
How fantastic that you are supporting people doing the marathon in Manchester, that’s amazing! Hope you get to do it next year.
The charity supports people of all ages. It was just started by a young athlete who went on to create online resources and workshops for young people with cancer, but the main aim of the charity is to get everyone living with or beyond cancer to exercise in whatever way they can. Please don’t worry about being over 30 - the 5K Your Way meet ups are attended by people of all ages (I am in my 50s).
Hopefully you can find some useful information on the website and good luck with your running!
Take care,
B
