British distance-running great Mo Farah has withdrawn from next month's Big Half race in London with an achilles injury, organisers announced on Wednesday.
The four-time Olympic gold medallist, preparing for the 2020 Games in Tokyo, suffered the minor injury in training.
Farah, 36, has won the half-marathon event for the past two years and was due to take on a field featuring Ethiopia star Kenenisa Bekele on March 1.
"I was really looking forward to racing the Vitality Big Half again," said Farah in a statement issued by event organisers.
"Everyone knows how much I love racing in London, but my priority is to be fit, healthy and competitive for the summer season and for that reason I have had to make the tough decision not to race this year."
