This week Planet Sport’s Tom Ellis reports from last Sunday’s Anniversary Games in London where many of the world’s top track and athletes were competing as part of their final preparations ahead of next month’s World Athletics Championships which will be held in the same stadium. We hear from world 100 metres hurdles world record holder Kendra Harrison and 2012 Olympic champion in the men’s 400 metres hurdles, Aries Merritt, both from the United States. We also talk to Great Britain’s double Olympic champion in the 5000 metres and 10,000 metres, Mo Farah, and race walker Tom Bosworth who set a new world record holder in the rarely-competed one mile race walk.
