While world record holder Eliud Kipchoge (38) is absent from the line-up, Bekele will be joined by compatriots Birhanu Legese (28) and Mosinet Geremew (30) as well as Kenya's Kelvin Kiptum (23) at the start line on April 23.

With Bekele and Kiptum, the second and third fastest of all time, in the race it will mark the first time two men who have run inside two hours and two minutes will compete in the same marathon.

Defending champion Amos Kipruto (30) of Kenya and world champion Ethiopian Tamirat Tola (31) are also entrants.

"London always has a really strong field and this year is the same so I know I will face a battle to defend my title, but I'm confident and looking forward to it," said Kipruto.

Britain's four-times Olympic distance champion Mo Farah (39) will also compete at his home race ahead of his likely retirement this year.
