Reigning Olympic and world champion Mo Farah fought off Kenyan tactics to defend his gold medal and win the men's 10,000-meter run in 27:01.13 on the first day of the IAAF World Championships in Beijing.
Farah is looking to become the first man in history to win the 5,000-meters and 10,000-meters in back-to-back world championships. Farah has not lost a race at the 10,000-meter distance since 2011.
The Kenyan contingent of Paul Tanui, Geoffrey Kamworor and Bedan Muchiri attempted to crack Farah by not allowing him to take the lead until the final lap. The Great Britain athlete unleashed a 54 second last lap to cross the finish line with his arms extended in celebration. Kamworor ended up with silver in 27:01.76 as Tanui settled for bronze in 27:02.83.
Olympic silver medalist Galen Rupp, who was the subject of doping allegations by BBCand ProPublica earlier in the summer, was left off the podium with a fifth place finish. Americans Hassan Mead (28:16.30) and Shadrack Kipchirchir (28:16.30) finished in 15th and 16th place respectively.
Here are other results from the first day of the world championships in Beijing:
