Ennis aiming for new high

Jessica Ennis believes she will have to set a new British record if she is to win Olympic gold in London this summer.

The heptathlete beat the previous UK best set by Denise Lewis in Austria last month and will continue her build-up to the games in London at this weekend's British trials, where she'll compete in the 200m, 100m hurdles, long jump and high jump. Ennis previously won World Championship gold in 2009 but failed to retain her title two years later as she lost out to Russian Tatyana Chernova. However, she is back up to world number one following her recent win in Austria and believes there still a lot to come from her ahead of the games. "It was great to get the record so early in the season, but yes, I think it's going to take that big score to win [at the Olympics]," she said. "I know that everyone else is competing well and some of the girls will go away and train even harder to make sure they are ready for London. "It is by no means over and there's still a lot to come from me, but I'm looking forward to it."
