Mo Farah will face world record holder Wilson KipsangÃ‚Â (Kenya) in a strong field competing at the 2014 London Marathon.
British double Olympic and world championÃ‚Â Farah ran half the race in 2013Ã‚Â and will make his full debut in the event on 13 April.
The 30-year-old will also face Olympic and world marathon champion Stephen Kiprotich over the 26.2-mile course.
“I am expecting it to be one of my toughest races and a real learning experience,” said Farah.
Farah became only the seventh man to win both theÃ‚Â 5,000m and 10,000mÃ‚Â at the same Olympics in the 2012 London Games.
Following his appearance in half of the 2013 London Marathon,Ã‚Â he also won both titles at the World ChampionshipsÃ‚Â in Russia last August.
Reigning London Marathon champion Tsegaye Kebede (Ethiopia)Ã‚Â and London course record holder Emmanuel MutaiÃ‚Â (Kenya) are again competing in this year’s race.
Kenenisa Bekele is the only notable absentee, with the Ethiopian set to make his marathon debut in Paris on 6 April instead.
“I gained a lot of valuable experience running part of the course alongside the top guys last year and can’t wait to race over the full distance this April,” said Farah.
“The London Marathon always attracts the world’s best runners to its elite fields and this year will be no different.
“I had another great year on the track in 2013, but the marathon is my main focus for this year.”
