GOLD medal hopeful Jessica Ennis believes she will have to pull out all the stops if she is to claim personal glory at next year’s Games in London.

The Sheffield-born athlete predicted that she will have to break her personal best and the British record to win Olympic gold next Summer.

“I’ll have to break the British record, definitely,” Ennis said. “I think it could take 6,900 points to win and that’s going to be really, really tough.”

Ennis has a personal best of 6,823 points, which she set in winning the European Championships in Barcelona last year and that is just eight points short of the British record, held by former Olympic champion Denise Lewis.

However, Russia’s Tatyana Chernova scored 6,880 points in taking Ennis’ world title in Daegu earlier this year.

Ennis paid the price for a poor javelin throw in Korea, but added: “It’s not like I’m chasing. I’m there. I made a couple of mistakes but I’m where I need to be.”

Meanwhile, the 25-year-old has revealed she will strictly limit her media work in 2012, adding: “When I start competing I will just say no to all the media and other stuff.

“It will all be over before you know it and the main thing now is staying injury-free and being in a position to give yourself the chance on the day.”
