London Landmarks 2026

I’m running London Landmarks Half Marathon in the fight for breath!

Some of you may be aware that our son Parker was recently diagnosed with Asthma after an 9 year fight with the hospital to get a diagnosis. Parker struggles throughout the year and cannot have a simple cold without hospital intervention. We are hoping now he is trialing new steroids he will find it easier to manage.

Every minute, someone in the UK is diagnosed with lung disease. I want to make a difference. I'm running London Landmarks for Asthma + Lung UK, 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 could go towards Health Care Advisors and Respiratory Specialists supporting someone with the information they need to live well.

Any support would be amazing in my fight for lung health!
