Jessica Ennis has long been trumpeted as Great Britain's major hope for a Gold medal next summer - can she replicate her form from last year's European Championships and take top billing again? 400m runner Christine Ohuruogu was Team GB's sole Athletics Gold medallist in Beijing in 2008, and, with just four medals won on track and field overall, an vast improvement is hoped for as the Athletics events get under way from 3 August at the Olympic Stadium.

Sir Chris Hoy, Bradley Wiggans et al were majestic in Beijing three years ago, riding to 12 medals, including seven Gold, as Team GB dominated. The Olympic Park velodrome should again be one of the most sought-after tickets of the Games as the track events take place between 2-7 August.
Tom Daley, who will still only be 18 by the Games, takes centre stage in front of an adoring home crowd at the Aquatics Centre as the Diving begins on 29 July. He endured a dissapointing Games in Beijing but two Golds at last year's Commonwealth Games and a strong showing at last month's British Championship suggest brighter things.
Traditionally one of Britain's stronger events, and with two Golds in Beijing, home crowds at the Eton Dorney Rowing Centre will be expectant of further success when competition gets under way on 28 July.
Ben Ainslie looks to medal for a fifth successive Games, following three consecutive Golds and a Silver in Atlanta in 1996. Weymouth Bay and Portland Harbour are the venues as events take place between 29 July and 11 August.
