Hot runnings

Well done to the many thousands who took part in the London marathon in the unseasonably warm April weather. It was the hottest running of the race since its inception in 1981, which made the efforts of participants even more commendable.

Our own Bryony Gordon was cooler than many, since she ran in her underwear to promote “body positivity” and to raise money for the mental health charity Heads Together. Matthew Fearn, the

Telegraph’s picture editor, ran his first marathon for Leukaemia Care in memory of Shawn Russell, a colleague who died last year. Altogether, millions of pounds will have been raised for the various charities supported by runners, making this arguably the world’s biggest annual fund-raising event. Congratulations all round.
