The Men's marathon at the 2011 World Championships in Athletics was held starting and finishing at Gukchae-bosang Memorial Park on September 4.
Running a casual pace to 15 km, first the Moroccan contingent tried to test the field.
After 25 km, it was down to Kirui, Vincent Kipruto, Eliud Kiptanui, Feyisa Lilesa and Abderrahime Bouramdane.
In that competition, the scoring is based on the cumulative time of the top three finishers for each team.
Perennial champion Japan finished second, a cumulative minute ahead of Morocco.
