Double Olympic champion Mo Farah  has lauched the first public sports event to take place at the Olympic Stadium since the Games last year.
A five-mile run ending at the stadium will be the first sporting event to be held at the newly-reopened Olympic Park this summer.
Up to 10,000 members of the public are set to take part in the National Lottery Anniversary Run on July 21.
Olympic 5,000m and 10,000m champion Farah said it is "wonderful" the public will be able to run on the track where Usain Bolt , Jessica Ennis and David Weir also won gold at London 2012.
He said: "It is fitting that the first people to run on the track since the end of London 2012 will be members of the British public who did so much to make the Olympic and Paralympic Games such a success.
"Running down the home straight to win gold for Britain last summer was one of the greatest experiences of my life."
