British London Olympic gold medal winners Jessica Ennis, Mo Farah and Greg Rutherford will compete at the Anniversary Games at the Olympic Park on July 26-28, British Athletics announced on Tuesday.
The 2012 heptathlon queen will double up in both the 100m hurdles and long jump, Farah will run in the 3,000m, while Rutherford will appear in the long jump.
This trio and two other British track and field medal winners at London 2012 will join 14 of the 16 home-based Paralympic medallists for the IAAF Diamond League and IPC International Challenge events.
"I have amazing memories of competing in the Olympic Stadium last year and it will be good to step out on that track again in front of a British crowd," Ennis said.
"I'll never forget the noise the crowd made when I competed last August and know that the draw of the stadium and the great line up of athletes will fill the stands and make it another incredible occasion.
"I am training hard and am getting excited about the prospect of getting out there and competing again this summer."
