The Queen, meanwhile, is touring the Olympic site following her surprise appearance with James Bond in a film shown during the opening ceremony.
The spectacle was watched by an average of 22.4m people in the UK.
The Queen, wearing a brooch given to her in 1948 - the year of the last London Olympics - ascended Anish Kapoor’s Olympic Orbit tower sculpture during her tour.
We knew she had a head for heights after last night’s opening ceremony helicopter shenanigans.
So there were no vertigo worries as the Queen ascended the £19.1m Orbit Tower at the start of her visit to Olympic Park this morning.
Her Majesty wasn’t one of the household names Olympic ticket-holders were expecting to see here and they flocked to the base of the 115-metre high steel wrangle to catch a glimpse of her.
Of those waiting, most were thrilled to see her in Royal blue so soon after she opened the Games of the XXX Olympiad. For Thomas Wallage, though, who says he has been looking forward to the Olympics all of his eight years, it was all about the Bentley that is chauffeuring her through the visit.
Outside the venues you can hear cheers as competitors are announced. And they were louder still at the Aquatic Centre for the Queen.
As she left for other sites including the Athlete’s Village, children were also braving new heights, roly-polying down the hill on the grass in the parklands.
She also visited the Aquatic Centre where there was a huge cheer for the monarch and the Duke of Edinburgh, who caught a glimpse of the women’s 400m individual medley.
