The world record is 7,291, set by American Jackie Joyner-Kersee at the Seoul Olympics in 1988. The news agencies are reporting that Jess has said she'll strictly limit her media work in 2012. In an interview with BBC Sport last month she said she planned to stay away from the Olympic Stadium in the build-up to the Games.
And she added: "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."
One thing is for sure, the Sheffield lass will be working hard and her website will be reporting all the way to London!
