The Ethiopian legend, Bekele, will line up against Great Britain's 4-time Olympic and 6-time World Champion Mo Farah and the fastest marathoner in history Kenya's Eliud Kipchoge on Sunday 22 April.
The 2018 London Marathon organizers have attracted total of 8 Olympic and 12 World Championship gold medalists.
Bekele finished third in 2016 and second last year while Kipchoge has won the London marathon in 2015 and 2016.
"This is a truly mouth-watering prospect." Hugh Brasher, Event Director said.
"I am thrilled to be returning to London for the third year in a row and would love to go one better than last year and win the race. Once again London has brought the best distance runners in the world together so I know it will not be easy." Bekele said.
Here's an interesting fact by track and field statistician, Jon Mulkeen @Statman_jon: "Bekele, Kipchoge & Farah have clashed once at cross country (2005 World Cross: Bekele 1st, Kipchoge 5th, Farah 37th) and once on the track (2009 World Champs 5000m: Bekele 1st, Kipchoge 5th, Farah 7th). The London Marathon will be their first clash on the roads."
