London's Olympic Stadium will host its first sporting event since the Games on the anniversary of the opening ceremony.
The London Grand Prix athletics meeting, part of the elite Diamond League series, is to be moved from its usual home at Crystal Palace and will take place on July 27, a year to the day after the Olympics began in spectacular fashion.
Mo Farah, who won gold medals in the 10,000 metres and 5,000m at the Olympics, said: "The atmosphere was electric during the Games, I'll never forget it, so it's great that the British fans, and athletes, will get to experience that again so soon after the Games."
Athletics tickets were among the most sought after for the Games and heptathlon gold medallist Jessica Ennis hopes the Grand Prix will give people who were unable to buy tickets a chance to see high-class athletics at the stadium.
She said: "It is brilliant to hear that the British Athletics London GP is going to be held at the Olympic Stadium a year after the Games.
"It will give athletes and fans who did not get to experience the amazing venue the chance to go there, and for those of us who had the most incredible experiences on the track and field, an opportunity to relive a few memories.
"Hopefully I will be there and using the competition as part of my preparation for the World Championships."
