Kenenisa Bekele, the unbeaten world champion since 2003, decided to defend his title, but his form was unknown as injuries had meant that he had not raced since early 2010.
Kenya, typically strong in the event, sent a team of 2007 bronze medallist Martin Mathathi, Peter Cheruiyot Kirui, and World Cross Country runner-up Paul Kipngetich Tanui.
[1][2] Zersenay Tadese set a fast pace for much of the race, a decision which soon reduced the leading pack to the Ethiopian and Kenyan teams, with the additions of the Eritrean, Mo Farah, and Galen Rupp.
The final 500 metres saw Farah take the lead with an injection of speed, with Imane Merga and Ibrahim Jeilan the only runners to follow him.
Having felt overlooked for the Ethiopian team for the 2008 Olympics and 2009 World Championships, Ibrahim had moved to Japan to prepare himself away from the major circuit.
