Farah hoping to be fresher for final
Mo Farah admitted he was tired in his 5,000m semi-final and he hopes to feel fresher for Saturday's final as he goes for gold again.
The 29-year-old's superb gold in the 10,000m last weekend has been one of the highlights of the Olympics so far but now the focus for the Team GB star is the shorter distance where he is again among the favourites to come out on top.
However, he admitted to being below par in the semi-final, where he finished third to qualify as one of five from the race and will look to be in better shape on Saturday.
Farah said: "I am definitely tired and I think it showed out there. The legs didn't feel great but that is what happens.
"Hopefully I will recover well and look forward to the final, forget about what I have done and rest up."
Farah faces a high-quality field on Saturday with US duo Galen Rupp and Bernard Lagat among his rivals alongside Ethiopian Dejen Gebremeskel, the fastest qualifier, and his fellow countryman Hagos Gebrhiwet.
