Five thousand members of the public became the first people to cross the finish line at the Olympic Stadium as they competed in the National Lottery Olympic Park Run on Saturday.
The five-mile run was the first ever public event to take place in the stadium which traversed the Olympic Park in east London.
Almost 43,000 members of the public entered a ballot last year to gain a place in the event and the chosen runners came from all over the United Kingdom
Princess Beatrice officially started the race before taking part in the event herself. The princess, who was the first member of the Royal Family to complete the London Marathon in 2010, also presented the fastest finisher medals.
She said: "I am thrilled to be able to play my part in such an historic occasion and it is fantastic to see the incredible transformation that the Olympic Park has undergone.
"I, like so many others running on the day, know that the experience of being one of the first to cross the Olympic finish line is an extraordinary moment in what promises to be a memorable year for the nation."
Applications to take part in the race numbered 42,678 and the 5,000 runners were randomly chosen to take part from across the United Kingdom.
The first person to officially cross the finish line was Stuart Bloor, 24, of Crewe, Cheshire. Bloor was born with Spina Bifida, leaving him wheelchair-bound since birth. He had his leg removed in 2007.
Bloor beat his rivals in the wheelchair race by several minutes, to clock in a time of 23 minutes and four seconds. He said: "To be honest, anything under half an hour would have been great but to be so far ahead is unbelievable. It hasn't sunk in yet."
The first runner to cross the Olympic finish line was Tommy Davies, 26, of Loughborough, who won the race with a time of 25 minutes 11 seconds and he said: "To win a race is fantastic, but to win a race here at this stadium is something which will not happen again. This is a once in a lifetime thing."
