Kory’s Story
Honouring Kory’s Memory Through Life-Saving Action
Seven years later, on 12 October 2025, another family experienced a devastating loss when Kory Russell collapsed near the finish line of the Royal Parks Half Marathon in London.
Despite the extraordinary efforts of medical professionals, Kory died in hospital. He was just 25.
Kory grew up in Sully in the Vale of Glamorgan and was a talented, ambitious and much-loved young man.
A former City of Cardiff Swimming Club swimmer, he had a lifelong passion for sport. He graduated from Loughborough University with a first-class degree and was building a successful career in finance in London.
He was also a talented chef, having previously worked in a Michelin-starred restaurant in Penarth, and was fiercely proud of his Welsh roots. A fluent Welsh speaker, Kory loved attending the Eisteddfod and maintained strong connections with his family, friends and community back home.
His family remember him for his kindness, determination, warmth and infectious smile.
His mum, Rhi, described him as "the kindest, most loving and hard-working person you could ever meet."
Kory's death was caused by a cardiac arrest following heat exhaustion during the race. His loss is a powerful reminder that cardiac emergencies can happen to anyone, including young, fit and active people.
In February 2026, Calon Hearts held special free heart screening sessions in Sully in Kory's memory, bringing potentially life-saving checks directly to his home community.
His family have since become passionate supporters of Calon Hearts, determined to raise awareness, encourage screening and help other families avoid similar heartbreak.
