Why run for Roy Castle Lung Cancer Foundation

Lung cancer is the UK’s biggest cancer killer, taking the lives of more people than breast, prostate and pancreatic cancers combined. Your support means we can continue our vital work and stop lung cancer from cutting lives short.

Roy Castle Lung Cancer Foundation is the only UK charity solely dedicated to supporting everyone affected by lung cancer. This means lung cancer, and lung cancer alone, is at the heart of everything we do. It is the focus of every research project we fund, every person we support, every life we save. It is our one and only priority.

I have my own place for Tough Mudder:

If you already have a place in Tough Mudder, we would love to have you on our team! There’s no fundraising commitment, but any money you can raise will help support our vital work to stop lung cancer from cutting lives short. Our fundraising team will support you with any fundraising you do, as well as give you tips and ideas to raise even more money.
