Cardiff marathon death of 'really fit' man 'so out of the blue'
Ben McDonald was 25 when he died after going into cardiac arrest at the finish line of the Cardiff Half Marathon in October 2018.
His family describe him as "really fit, really healthy, funny and smiling."
A defibrillator was used on Ben, and although it did not save him, his family want more of them in public places.
A coroner's report concluded he died from sudden arrhythmic death syndrome (SADs).
