Jessica Ennis-Hill will make her competitive return to athletics for the first time since giving birth at the Great CityGames in Manchester on 9 May, the Olympic heptathlon champion has announced.

Ennis-Hill has not competed since the London Anniversary Games in 2013 following the birth of her son Reggie in July but after returning to training will intensify her preparation for the Gotzis Hypo-Meeting later in the month and August's World Athletics Championships.

The 29-year-old will compete in the 100m hurdles alongside recently crowned European indoor pentathlon champion Katarina Johnson-Thompson in a hotly anticipated race ahead of the British pair's pursuit of Olympic gold in Rio in the heptathlon competition.

"I'm really looking forward to making my competitive return at the Great CityGames Manchester," the Sheffield-born athlete said. "The atmosphere is always amazing there.

"Street athletics is a lot of fun, not only you are really close to the fans, but the energy around the Morrison's Great Manchester Run weekend is fantastic, as the elite races and the mass participation run bring the city together in a celebration of running."
