APF Puffers and EPIC Puffers are a group from the Interstitial Lung Disease (ILD) Service in the Royal Devon and Exeter Hospital and the University of Exeter raising funds for the patient charity Action for Pulmonary Fibrosis (APF) and the ILD research at the University (EPIC). We are all taking on a challenge in the Great West Run whether it is The Half marathon or the Community Mile.
