About British Lung Foundation

1 in 5 people in the UK have a lung disease. The BLF is the only UK charity looking after everyone who struggles to breathe, no matter what their condition.

Our research finds new treatments and cures. We help people with a lung condition take control of their lives. And together, we’re campaigning for better lung health.

It’s a big job and we can’t do it alone. This is why we need your support.

By doing The Big 100, you can help make sure we're there for people with lung disease, whenever they need us.
