Jepkosgei, the winner in 2021, came second in 2:18:43 as Sifan Hassan, the 2023 champion, settled for third place in 2:18:59.
Ethiopia’s Tigst Assefa dropped Kenya’s Joycline Jepkosgei after 35 kilometres to claim her maiden London Marathon title in a women-only world record time on Sunday in the British capital city.
