Virgin Money London Marathon champion Daniel Wanjiru is to return to the streets of the capital on March 4 to race The Big Half.
The 25-year-old Kenyan, who claimed the biggest win of his career so far in London last April, will take on Britain's 10-time global track champion Mo Farah and world marathon fourth-placer Callum Hawkins when he races over 13.1 miles in March.
With a half-marathon personal best of 59:20 set in 2016, Wanjiru is the fastest of the three men on paper.
Farah's UK record is 59:32, which he set in Lisbon in 2015, while Hawkins ran a Scottish record of 60:00 in Japan last February.
"I am really looking forward to returning to London to race in The Big Half," said Wanjiru. "I have very happy memories of running on London roads and the fantastic crowds.
"It is a privilege to be racing such a legend as Sir Mo Farah and I know that both he and Callum Hawkins will be big rivals to me in this race. The Big Half will be a great race."
The Big Half starts by Tower Bridge and finishes in front of the Cutty Sark in Greenwich, using many of the same roads as the first half of the Virgin Money London Marathon.
The race is part of a one-day festival centred around the half-marathon distance which aims to be ‘truly global and uniquely local’.
