Highlights, Day 4

Gabby Logan presents highlights of day four's action at the 15th World Championships from Beijing, China.

Great Britain's Greg Rutherford was aiming to complete the full set of Olympic, European, Commonwealth and World Championship gold medals. By doing so, he would join decathlon legend Daley Thompson, 400m hurdler Sally Gunnell and triple jumper Jonathan Edwards as the only Britons to hold all four titles simultaneously.

David Rudisha has struggled with injuries since his sensational gold medal at the London Olympics but will look to put all that behind him in the final of the 800m.

Gabby will be joined by four-time Olympic champion Michael Johnson for expert analysis and reaction.
