All the favoured athletes progressed through a series of tactically-run heats on the first day of competition, with Baala, Kiprop, Choge and Deresse Mekonnen the four race winners.[2] Moroccan Amine Laalou won the first semi-final, followed by Americans Lopez Lomong and Lagat, while Kiprop and Leonel Manzano both finished quickly to take the top two qualifying spots in the second race. The only high-profile athlete to be eliminated in the semi-finals was Keitany, who did not start, putting an end to any hopes of a Kenyan medal sweep.[3]
The final race began slowly and, as the athletes reached the last lap, they remained in a tight pack led by Mekonnen. Choge and Mohamed Moustaoui closely followed as he approached the final straight, but the race remained open.[4]Yusuf Saad Kamel took the lead in the final straight, scoring a surprise gold medal.[5] Mekonnen maintained his pace to take the silver medal and defending champion Lagat had a quick burst near the finish to win the bronze. Kiprop, one of the pre-race favourites, left himself too much ground to cover, eventually ending up fourth, with Choge and Baala alongside him.[4]
Bahrain's Kamel, born in Kenya as Gregory Konchellah, followed in the footsteps of his father Billy Konchellah, who won the 800 m at the 1987 and 1991 World Championships.[5] Mekonnen's silver was Ethiopia's first ever World Championship medal in the 1500 m.[4] Lagat's bronze was his third in the 1500 m, after his silver in 2001 and a gold in 2007.[5]
