That will be one of four medal races during the evening session, which also includes the finals of the men's 100m Breaststroke, women's 100m Butterfly and the women's 400m Freestyle, when the home support could lift the roof off the venue if Rebecca Adlington can defend the title she won at Beijing 2008.
Wu Minxia will be out to make history by equalling fellow Chinese diver Guo Jingjing's Olympic Games record of winning six medals when she competes in the women’s 3m Synchro alongside He Zi.
There will be royalty participating too - and not a parachute in sight - as Zara Phillips makes her long-awaited Olympic Equestrian debut at Greenwich Park.
In Cycling, it is the women’s turn to battle it out in the Road Race around a 140km course, which starts and finishes on The Mall and features two climbs of Box Hill.
Marianne Vos of the Netherlands is one of the favourites but will face tough competition from Britain’s defending champion Nicole Cooke and her team-mate Lizzie Armitstead, as well as the likes of Italy's Giorgia Bronzini and Shelley Olds of the United States.
