1 in 5 people in the UK has a lung condition. That means 10,000 new diagnoses per week. I'm running the London Marathon for the British Lung Foundation, the only UK charity looking after the nation's lungs. Every pound I'm able to raise will take us a step closer to a world without lung disease. Just £8 allows one of the BLF's nurses to answer a call on the Helpline, offering support to someone in need. I'd be very grateful for any donations you could make!
