British athletics great Mo Farah paying tribute to the late boxing legend Muhammad Ali on Sunday by striking a boxing pose (pictured) after he broke David Moorcroft's 34-year-old British 3,000m record at the Birmingham Diamond League meet. The 33-year-old double Olympic champion clocked 7min 32.62sec to take 0.1sec off Moorcroft's mark. He now aims to emulate the legendary Finn Lasse Viren, who did the distance double in 1972 and 1976, at August's Rio Olympics by retaining his 5,000m and 10,000m titles. "I'm in great shape. I've just got to believe in myself," said the Somalia-born athlete. "I want to make history in Rio... and I know I'm going to have to dig deep."
