There will be 20 athletes in the women’s elite race and 43 in the men’s.
Great Britain’s Becky Briggs and Alice Wright will participate in the women’s race after competing in the marathon at the 2022 European Athletics Championships.
Joining them are Anya Culling, Rachel Hodgkinson, Helen Gaunt, Mhairi Maclennan and Lucy Reid.
Ethiopia’s new world record holder Tigst Assefa, Kenya’s trio of Brigid Kosgei, Ruth Chepngetich and Olympic champion Peres Jepchirchir, and Ethiopia’s 2020 London Marathon champion Yalemzerf Yehualaw will all be there.
They will aim to break the women’s only world record – the fastest time by a woman in a marathon that was not a mixed-gender event – set by Kenya’s Mary Keitany in 2017 (two hours 17 minutes and one second).
In the men’s race, Emile Cairess returns after becoming the third-fastest Briton on his London Marathon debut last year. He is joined by Callum Hawkins, who finished fourth at the World Championships.
Compatriot Marc Scott, a 3,000m bronze medallist at the 2022 World Indoor Championships – will make his marathon debut, as will Mahamed Mahamed.
The elite men’s race is headlined by Ethiopia’s Tamirat Tola, who is the New York City Marathon champion, Mosinet Geremew, who is the seventh-fastest man in history, and Kenya’s Alexander Mutiso Munyao.
In the wheelchair races, Britain’s David Weir – the most decorated athlete in the event’s history with a total of eight wins – is set to compete in his 25th consecutive London Marathon.
