Kory Russell, a 25-year-old finance worker, collapsed and died during his first half marathon after his body temperature rose above 40C, an inquest has heard. The Royal Parks Half Marathon in London in October 2023 proved fatal due to heat exhaustion-induced cardiac arrest.
Race Day Collapse and Medical Response
Mr Russell, from Sully, south Wales, had completed shorter races but never a half marathon. He was described as “meticulous” in his preparation and had no prior heart issues. Paramedics treated him at the finish line, performing CPR in a medical tent and continuing in the ambulance to St Mary’s Hospital in Paddington. Despite cooling techniques, his core temperature remained over 40C. He was pronounced dead at 11.55am.
More than 20 medical staff provided treatment for over 40 minutes, double the national guideline of 20 minutes for CPR. Assistant Coroner Jean Harkin noted, “This time was extremely long and shows you just how committed the health services were.”
Background and Family Tribute
Mr Russell, the eldest of four children, worked as a financial officer at State Street Investment Management after earning a first-class degree in economics and finance from Loughborough University. Post-mortem tests confirmed no alcohol in his system. His mother, Rhi Russell, has since become vice president of Calon Hearts UK, a cardiac screening charity.
His father, Matt Russell, told the inquest: “Kory was the kindest, most loving and hard-working person you could ever meet. He gave everything his all, whether it was work, sport, family or friendships. He had such a big heart and a personality that would light up any room. We are all heartbroken. He will be forever missed and remembered with endless love.”
Organizer Response
A Royal Parks Half Marathon spokesperson said: “Everyone involved in the organisation of the Royal Parks Half Marathon would like to express sincere condolences to Kory's family and friends.”
