I’m running the London Marathon 2026 to fight for lung health!

Every minute, someone in the UK is diagnosed with a lung condition.  I'm running the London Marathon 2025 for Asthma + Lung UK, the only UK charity that fights for everyone’s right to breathe. 

In 2012 my dad was diagnosed with COPD. Since then his condition has worsened and he has recently been informed that he has stage 5 COPD which is very severe COPD. This means that even the simplest of tasks such as walking from one room to another can be very difficult making him extremely breathless and receives regular care from our local respiratory team.

At the age of 4 I was diagnosed with asthma and growing up I would suffer from asthma attacks. Through medication and a great asthma team I have learnt to manage my asthma effectively but it can still have an impact on me depending on the weather and air pollution throughout the year.

1 in 5 of us will develop a lung condition during our lifetime. There's a new diagnosis every minute so we need to do all we can to help find a cure for them. Asthma + Lung UK who are the only UK charity that fights for everyone’s right to breathe. Every pound I'm able to raise will take us a step closer to a world where everyone has healthy lungs.

Just £22 allows one of Asthma + Lung UK's nurses to answer a call on the Helpline, offering potentially lifesaving advice. I'd be very grateful for any donations you could make which will make a real difference to others like my dad and myself. Together we can fight lung disease.
