The Olympic flame began its seven-day tour of London in Greenwich, where 15-year-old Natasha Sinha set off from the Royal Observatory.
Day 64 takes in five of the capital's six Olympic boroughs - Greenwich, Newham, Tower Hamlets, Hackney and Waltham Forest - with 143 people taking their turn to carry the torch.
Round-the-World yachtsman Robin Knox-Johnston was among the early torchbearers, carrying the torch around the newly-restored tea clipper, the Cutty Sark.
As the relay passed through Woolwich, members of the King's Troop Royal Horse Artillery joined paratrooper Jaco van Gass - who was severely injured while serving in Afghanistan - as he took his turn with the Olympic flame.
One of the day's early highlights was a trip to the top of the North Greenwich Arena - formerly the Millennium Dome - where 6ft 10in basketball star John Amaechi proved he had a head for heights when taking the flame from Olympic gymnast Nadia Comaneci.
Singer Paloma Faith added a bit of glamour to proceedings by wearing bright red high heels and cropping her official torchbearer uniform during her leg in Newham.
Among the athletes to carry the torch was Tessa Sanderson-White, who won gold in the javelin at the 1984 Los Angeles Games.
And a man hoping to emulate her by clinching gold in the field this year is triple jumper Phillips Idowu. At a special event in Stratford, he told the crowd he was "full of emotion" about carrying the Olympic flame and hoped to "make them proud" at the Games.
There was a carnival atmosphere in Stratford - near to the Olympic Park - as spectators waited for the flame's arrival.
The crowds were thick along the Mile End Road as Polish explorer and double amputee Jasiek Mela took his turn with the flame.
Across the city, at Battersea Park, runners were treated to their own Olympic moment courtesy of a giant set of Olympic rings. They were being floated along the Thames on a barge.
The day's last torchbearer was Bolton footballer Fabrice Muamba, who suffered a cardiac arrest during a match in March. He told the crowds of his recovery: "What happened to me is a miracle and I thank God that I am alive and able to do this now. I am just enjoying my life and all of this in Walthamstow today."
