The athletics programme hits full swing with Jessica Ennis and Mo Farah going for gold and the likes of Usain Bolt and Oscar Pistorius performing for the first time.
Team GB golden girl Jessica Ennis enters the second and final day of the women's heptathlon with the weight of a nation on her shoulders while 10,000m runner Mo Farah should also be in the athletics mix for the home nation in the Olympic Stadium. Double amputee Oscar Pretorius – the South Africa 'Blade Runner' – makes history in the 400m heats while the fastest man in the world, Jamaica's Usain Bolt, makes his first appearance at London 2012 in the 100m heats. Bolt's countryman and main rival Yohan Blake will also be in action, as will Justin Gatlin and Asafa Powell. If things go according to plan for Team GB, there could be a deluge of medals on Day Eight: Helen Jenkins one of the favourites to win the women's triathlon in Hyde Park, the women's pursuit track cycling team are in action in the Velodrome while at Eton Dorney four medal events include the men's lightweight double skulls and the men's four. World number one trampoline gymnast Kat Driscoll – who used to work full time in a bank until two years ago – is up against the agile Chinese and Russian bouncers at the North Greenwich Arena.
Gold medals up for grabs: 25
Today's medal sports: triathlon, rowing, athletics, tennis, shooting, badminton, trampoline, track cycling, weightlifting, fencing, swimming
It's the weekend! Which means you're free to go and see Daley Thompson at BT House in Hyde Park at 1.30pm and return later to see McFly on the main BT London Live stage at 5.20pm followed by Saint Etienne at 10.05pm. It's also a chance to explore all the extra things going on in London because of the Olympics. Many of the Olympic National Hospitality Houses have their own villages where you can find out more about each country. You can see the Olympic Park in LEGO at the Danish Village in St Katherine's Dock, ice skating at the Russia.Sochi Park and free art exhibitions at Casa Brasil at Somerset House where the free to view Rolling Stones: 50 exhibition continues. Saturday also presents a chance to get out and see the Olympics on a big screen in a park - Hyde Park and Victoria Park are the main official places to go but there are also big screens in Walthamstow and Potters Fields. But if you'd rather avoid the sporting action altogether there are two Prom concerts: Prom 28 which is performed by two Ulster orchestras; and Prom 29 in which the National Youth Orchestra of Great Britain perform New Music 20x12 commission as part of the Cultural Olympiad. Proms Plus Late follows, giving ticket holders the chance to enjoy an informal post-Prom music and poetry from emerging young talent. In a series of special late night events, Tate Modern dims the lights to create an atmospheric event to experience the Surrealism galleries. It's free to book but you will need to buy an Olafur Eliasson Little Sun lamp (£16.50 each at the Tate Modern shop) to take part (every Saturday from 28th July to 18th August, 10.15pm to midnight). Tate Modern also has some excellent exhibitions at the moment: there's the Damien Hirst and Edvard Munch exhibitions, Tino Sehgal's live Turbine commission and the Tate Tanks where a new installation by Sung Hwan Kim is just one of the works on display as part of the Art in Action series. Turner Prize winning artist Jeremy Deller's Sacrilege (aka the Stonehenge you can bounce on) is at Burgess Park.
Last chance: It's the fifth and final night of the Boom Boom Club at London Wonderground; John Peel's Shed closes at the Soho Theatre; Posh ends its run at the Duke of York's; and Opera Holland Park sings its last with a final performance of Daniel Slater's Eugene Onegin.
