Isa Guha and Mark Chapman present the key moments from the busiest day of the Olympics so far, with a plethora of star names in action as 27 gold medals were decided. The women's athletics 100m final was the day's showpiece event, with Britain's poster girl Dina Asher-Smith hoping to be in the mix against America's Sha'Carri Richardson and Jamaican Shelly-Ann Fraser-Pryce. British gymnast Max Whitlock was seeking a fourth successive pommel horse medal, while American superstar Simone Biles sought to reclaim her women's vault title. Tennis medals were decided in the women's singles and men's doubles at Roland Garros and some of cycling's most familiar faces were in action in the men's road race on the streets of Paris.
