A 36-year-old man passed away after passing out close to the finish line of the London Marathon.
He received quick care between miles 23 and 24, according to the organisers, and an ambulance was on the way in three minutes. However, he eventually passed away in the hospital.
The man was from southeast England and no further details will be released as the family have asked for privacy.
The cause of death will be established later through a medical examination.
Organizers of the event said in a statement: “Everyone involved in the organization of the London Marathon would like to express sincere condolences to his family and friends.”
More than 40,000 runners competed in Sunday’s event.
Kenyan Amos Kipruto won the men’s race in 2:04:39, while Ethiopian Yalemzerf Yehualaw was the fastest woman in 2:17.25.
Thousands lined the 26.2-mile route to cheer on the elite athletes and the masses of amateur runners who raise money for charity.
