A man who collapsed near the 25-mile mark at the 2021 London Marathon is set to return in 2023 to raise money for St John Ambulance, whose quick actions he credits with preventing “more lasting damage”.
Keen runner David Blackmore, 36, from King’s Lynn in Norfolk, collapsed with heat stroke in 2021 during his first London Marathon attempt and was unable to finish, saying “my dream turned into a nightmare so close to the end”.
