Cambridge man breaks Guinness World Record for fastest marathon by runner with an artificial heart valve
Three years ago, Cambridge man Alex Hunt faced the most challenging time of his life.
Fearing he might never see his daughters grow up, he faced open heart surgery for a bicuspid aortic valve.
This common congenital heart defect causes blood flow issues and, if left untreated, could lead to serious complications including heart failure.
But after an artificial valve was fitted at Royal Papworth Hospital, he has returned to health - and been able to indulge his love of running in some style.
Alex, 37, has broken the Guinness World Record for running the fastest marathon by somebody with an artificial heart valve.
He conquered the Stevenage marathon last October in the impressive time of three hours and six minutes – smashing the previous world record by 45 minutes.
After several months of waiting for confirmation from Guinness World Records, his achievement has now been officially recognised.
“My legs were starting to fail me by 24 miles, but stubbornness and caffeine got me through it,” said Alex, who faced winds of up to 40mph on the day and some “soul-destroying”.
He described it as one of the toughest physical challenges he has ever tackled.
“Before the operation I was a keen runner,” he said. “Thanks to the amazing staff and treatment I received at Royal Papworth Hospital, I can return to my love of running and am delighted to have broken the world record at the same time. “
Steven Tsui, consultant in cardiothoracic surgery congratulated Alex on his “outstanding” achievement and added: “Alex breaking the Guinness World Record is testament to his strength and determination to get back on his feet after a major operation. Well done to Alex for his outstanding personal achievement and thank you for your support for Royal Papworth Hospital Charity.”
Alex raised £1,700 for Royal Papworth Charity by running the marathon.
The charity supports the Cambridge Biomedical Campus-based hospital in providing the highest standards of care and helps drive forward new ways of treating heart and lung disease.
The charity is able to fund specialist equipment to get patients home quicker and support for relatives with last-minute accommodation – keeping families together during difficult times.
It helps with the cost of education and training of staff and volunteers to ensure patients receive the best care and treatment possible and helps fund research that pushes the boundaries of heart and lung disease treatments.
