Sheffield Pulmonary Vascular Disease Unit nurses John Harrington, Sammy Abraham and Charlotte Peirson are lacing up their trainers to tackle the mighty Sheffield Half Marathon for the PHA UK.

Famous for its punishing hills, the 13.1 mile route tests the best of athletes... so let's all pray for these three ;-)

Seriously, the trio have been training hard and will be thinking of their patients when they take on the race in April.

They have chosen to raise money for the PHA UK in support of everyone impacted by pulmonary hypertension. The breathlessness they will experience during the event will be short-lived, but those with PH endure it every day.

Pulmonary hypertension (PH) is rare, serious and misunderstood. It has a huge impact on people’s lives, and the PHA UK is dedicated to reducing that burden through support, advice, information and advocacy. They raise awareness and fund research to provide better treatments, with the hope of one day finding a cure for this devastating disease.

The PHA UK receives no government funding, so every penny donated plays a vital role in helping them support people to live better lives with PH.
