Matt Campbell, aged 29, a professional chef from the Lake District, has died after collapsing in Sunday’s London Marathon.

Campbell, who featured on television in Masterchef: The Professionals last year, collapsed at the 22.5 mile mark and, although he received medical treatment on the scene from race doctors, later died in hospital.

The marathon this year was run in record temperatures, which reached 23.2C (74F) at one stage with reports that more runners needed treatment than in past years.

In a statement, London Marathon organisers said: “Matt was a well-known chef who featured in MasterChef: The Professionals last year, inspiring viewers with his nutritional gastronomy movement and forward-thinking ideas. He was running for the Brathay Trust and in memory of his father, Martin, who died in the summer of 2016.

“Matt’s family today paid tribute to their inspirational son and brother, who was a keen marathon runner and had earlier this month completed the Manchester Marathon in under three hours.

“Matt’s chosen charity, the Brathay Trust, inspires vulnerable young people to make positive changes in their lives. 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.”
