Nike has released an inspiration short film called "Smile". It follows British Olympic gold medal winner Mo Farah as he undergoes a gruelling training regime, giving viewers an unprecedented insight into the runner's journey and tough training moments that, in the end, make the final race look easy.
Narration comes from London-born spoken word artist George the Poet, who recites:
"You smiled a smile that made it look easy. Made people stop and stare. The happiness you felt you gave it so freely. They would never guess what got you there."
