A former MasterChef: The Professionals contestant has died at just 29-years-old while taking part in the London Marathon.
Matt Campbell collapsed at the 22.5-mile mark and while he was given medical treatment from race doctors he later died in hospital.
The London Marathon marked Matt's second marathon of the month - he had previously run the Manchester Marathon on the 8th April in under 3 hours.
There's no exact cause of death just yet, and although Matt was an experienced runner, yesterday's London Marathon was the hottest on record with temperatures reaching 23.2C (73.8F).
In a statement, race organisers said: "Everyone involved in the organisation of the London Marathon would like to express our sincere condolences to Matt's family and friends.
"No further details will be released and the family has asked for privacy.
"The exact cause of death will be established by later medical examination."
A spokeswoman for MasterChef said: "We are shocked and saddened to hear the news about Matt Campbell, one of our talented contestants from last year.
"It was a privilege to have him on the show. He will always be remembered for producing for some of the most innovative and groundbreaking food that we saw in the series.
"From the whole MasterChef team, our sincere condolences and thoughts are with his family and friends."
