LONDON (AP) -- Double Olympic long-distance champion Mo Farah says he will run his first full marathon in the prestigious London event in 2014.
The 29-year-old Farah won gold in the 5,000 and 10,000 meters for Britain at the London Games last year but has always said he would eventually move up to the marathon, potentially in time for the Rio de Janeiro Olympics in 2016.
Farah says he has entered this year's London Marathon, on April 21, but will only run half the course to "allow me to understand the course and the systems I will need when I run the full distance."
London Marathon race director Hugh Brasher says organizers "are full of anticipation for his marathon debut in 2014."
Farah will compete in a half-marathon in New Orleans on Feb. 24.
