A key warm-up event for the forthcoming London 2012 Games has taken place at the Olympic Stadium.
The National Lottery Olympic Park Run saw 5,000 members of the public take part in a special five-mile run around key venues for the Games before crossing the finishing line of the Olympic Park running track.
Each runner was selected randomly from nearly 43,000 ballots and even included Princess Beatrice plus other sporting celebrities such as runner Ewan Thomas and Paralympic winner Danny Crates.
"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," explained the princess.
She added: "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."
The overall winner of the race, which took in the Olympic velodrome and aquatics centre, was Tommy Davies, the 26-year-old runner from Loughborough who recorded a time of 25 minutes and 11 seconds.
Located in the southern area of the Olympic village, the stadium will be able to accommodate 80,000 spectators during London 2012 and boasts impressive facilities for athletes and visitors staying at central London hotels, including an 80-metre warm-up track.
A total of 208 events will take place at the venue and it is the location for both the opening and closing ceremonies of the athletics and Paralympic Games.
