This week Planet Sport\u2019s Tom Ellis reports from last Sunday\u2019s Anniversary Games in London where many of the world\u2019s top track and athletes were competing as part of their final preparations ahead of next month\u2019s 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\u2019s 400 metres hurdles, Aries Merritt, both from the United States. We also talk to Great Britain\u2019s 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.
