I never doubt myself - Farah
- From the section Athletics
Britain's Mo Farah says he "never doubts himself" as he prepares to defend his world championship titles in Beijing amidst doping allegations regarding his coach Alberto Salazar.
The 5,000m and 10,000 champion has found the scrutiny "hard" but is "happy when I'm training" and believes "you have to be happy to run well".
Farah will compete in the 10,000m on Saturday, the opening day of the championship, as he looks to make history as the first athlete to win both events at consecutive world championships.
