About us

Join Team CF for the 2025 TCS London Marathon and help us unite for a life unlimited! 

Cystic Fibrosis Trust is the charity uniting people to stop cystic fibrosis (CF). We fund vital research, improve care, speak out and race towards effective treatments for all. We won't stop until everyone with cystic fibrosis can live without limits.

Cystic Fibrosis Trust is the UK's leading charity supporting people with cystic fibrosis (CF). 

Cystic fibrosis (CF) is a genetic condition which causes sticky mucus to build up in the lungs and digestive system. It affects more than 10,800 people in the UK. One in 25 of us carries the faulty gene that causes it, usually without knowing.

Since 1964, we've supported people with cystic fibrosis to live longer, healthier lives - and we won’t stop until everyone can live without limits imposed by CF.
