Seven years after her lung collapsed, Harriet Davidson, now 32, has embarked on an extraordinary challenge to run four marathons in four days. This endeavor, which began on February 25th, marking her third wedding anniversary, is a testament to her resilience in living with lymphangioleiomyomatosis (LAM).

Affecting approximately 300 women in the UK, the disease presents significant challenges, with treatment options including lung transplants or facing early mortality.
Initially, Davidson struggled with the diagnosis, experiencing denial and uncertainty about her future. However, through medication to stabilize her lung function and a shift in perspective, she has found strength and positivity. Her determination has been hailed as inspiring by healthcare professionals, highlighting the individual nature of living with LAM.
