Thousands of marathon runners crossed the finish line of the 45th TCS London Marathon as temperatures in the English capital reached 22.2°C.
More than 56,000 runners were expected to take part in the 26.2-mile course, including celebrities, MPs and the fathers of two girls killed in the Southport attack.
Crowds of spectators, many carrying signs, filled the city streets to cheer on the runners and wave to their loved ones.
London could set a new record for the world's largest marathon, currently held by the TCS New York Marathon in November, which had 55,646 finishers.
Those involved included David Stancombe and Sergio Aguiar, whose daughters Elsie Dot Stancombe, seven, and Alice da Silva Aguiar, nine, were victims of a stabbing spree in Southport last summer.
They are raising money for initiatives in memory of their daughters and six-year-old Bibi King, who was killed in July during a Taylor Swift-inspired dance class.
In a video message posted on X, UK Prime Minister Sir Keir Starmer wished the couple “all the best”, adding: “The whole country admires your courage and resilience.”
Mr Stancombe told BBC Breakfast: “Even now it amazes me that so many people are aware of this and you get messages from the prime minister.”
Among the celebrities taking part this year was radio presenter Adele Roberts, who said she hoped her record-breaking marathon runs would inspire people suffering from cancer that they could “achieve anything”.
Roberts, who previously underwent treatment for bowel cancer, broke the record for the fastest combined time across all World Marathon Major races by completing the London Marathon.
She added: “I just kept thinking the opposite: pain is a privilege.
“I've been through a lot in my cancer recovery and every step of the way, even though it was painful, I was thinking, 'You're alive, you're lucky to be going through this,' so it's been amazing.”
Many marathon participants competed in fancy dress, hoping their unusual outfits would help raise more money for their chosen charities.
