If you missed out on the Olympics three years ago (understandably many of us vacated London in a panic over crowded public transport) now's your chance to see top athletes compete, as Sainsbury's Anniversary Olympic Games and National Paralympic Day are returning to Queen Elizabeth Park in Stratford. We've selected our favourite adrenaline-fuelled images which capture the spirit of the sporting events, as well as the nervous anticipation and tensions that arose leading up the Olympics.
