It sets up the possibility of an intriguing head-to-head with her fellow British athlete Katarina Johnson-Thompson, the brilliant multi-eventer who led the world heptathlon rankings last year and won pentathlon gold at the European Indoor Athletics Championships last month – possibly in the long jump or 100m hurdles.
Mo Farah has also announced that he will compete in the Diamond League event, which takes place between 24-26 July, four weeks before the start of the world championships in Beijing.
Ennis-Hill, who has not competed since tackling the 110m hurdles and long jump at the Anniversary Games in 2013, said she was delighted to be back. “I am really looking forward to it,” she said. “The 2012 Olympics were an incredible experience for me and it will be very special to step out on that track again. It will be amazing to compete in front of all our British fans who I am sure will have their own memories of the London Games too.”
But the 29-year-old, who missed most of the 2013 season because of achilles and ankle injuries and all of last year because of the birth of her son Reggie, said she was cautious about expecting to much from herself on her comeback.
“My main goal this season is to be as competitive as possible with the long-term goal being the Rio Olympics,” she added. “Diamond League meetings always have the best athletes in the world so I’m sure this will be a good test for me.
“I want to perform well being back on the big stage in London but I will be realistic as 2015 is about the challenge of getting back to competitive shape after having my little boy and ultimately making the necessary progression to be at my best for Rio.”
