I want a numbered list of all athletes who are mentioned to be British.

The elite men's race featured four of the fastest five competitors in history: Kenenisa Bekele, Kelvin Kiptum, Birhanu Legese and Mosinet Geremew.[14] Bekele has won multiple Olympic medals and Kiptum recorded the fastest marathon debut ever at the 2022 Valencia Marathon.[15] Amos Kipruto, who won the 2022 race, also returned in 2023.[14] Other competitors included Tamirat Tola, who won the marathon event at the 2022 World Athletics Championships, Geoffrey Kamworor, who has won two New York City Marathons, Leul Gebresilase, who finished second at the 2022 London Marathon, and Vincent Kipchumba, who finished second in both 2020 and 2021.[15] Briton Mo Farah raced in his final London Marathon, and other British athletes included Weynay Ghebresilasie, the fastest finishing Briton in 2022, Emile Cairess,[16] Chris Thompson[17] and Dewi Griffiths.[18] World record holder Eliud Kipchoge did not compete in London, as he chose to race the 2023 Boston Marathon instead.[14]
