British heptathlete Jessica Ennis-Hill is hopeful that her appearance at the Anniversary Games will be another step towards improving her form ahead of the Olympics in 2016.
Ennis-Hill hasn't competed in over a year after giving birth last summer, but ahead of her Olympic title defence in Rio next year, the Sheffield athlete is aiming to compete regularly during 2015.
The 29-year-old is quoted by BBC Sport as saying: "My race schedule is starting to take shape and it will be good to compete.
"My main goal this season is to be as competitive as possible with the long term goal being at the Rio Olympics."
The Anniversary Games take place at the Olympic Stadium on July 24 and 25.
