Ennis-Hill unsure over Worlds

Jessica Ennis-Hill admitted her World Championship hopes were in the balance after enduring a frustrating return to the Olympic Stadium.

The London 2012 heptathlon champion was back at the scene of last summer's gold medal triumph, but this time there was rather less for her to cheer about.

The 26-year-old, who is on her way back from an Achilles tendon injury which has played havoc with her season, followed a steady if unspectacular 100 metres hurdles run with a poor long jump at the Sainsbury's Anniversary Games.

She said yesterday this was the acid test of her fitness, and although she came through both events unscathed, she could now be fighting a losing battle to be fit for the World Championships. The Moscow showpiece is just two weeks away.

"It's frustrating, because I always want to be at my best and I'm obviously not at my best at the moment. I'm so glad I competed and got to experience this crowd again, but I'm definitely not where I'd like to be." - Jessica Ennis-Hill
