When you take on The Big 100, you’re leading the fight against lung disease.

Over 12 million people in the UK have a lung condition. As social restrictions ease, many of us may feel nervous about getting out there again. The Big 100 is a safe way to support those who struggle to breathe. Join us!

By doing The Big 100 you will be...

Holding change-makers to account

We both campaign for better UK lung health policies.

£12 could buy a school air pollution monitor to influence policy changes.

Enabling life-saving research

We both fund world class research projects, to improve treatments and develop cures.

£14 could fund an hour of vital research, giving hope to those with lung conditions.

Funding expert advice

We both offer life changing medical and practical advice through our website and Helpline.

£22 allows one of our respiratory nurses to talk to someone in need.

There are 60 new diagnoses of lung disease every hour

By the time you’ve signed up for The Big 100, two more people will have received life changing news.

We’re a lifeline for people with lung disease and we’re thrilled to be working together – we want you on our team!
