The undoubted golden girl of British track and field, Jessica Ennis is hoping to fulfill the gold part in delivering the medal that matters during this summer’s heptathlon. The 26-year-old is probably a slight favorite, given her home-field advantage and the fact that she broke Denise Lewis’ British record in May while storming to success in Gotzis, Austria. Lewis set her mark of 6,831 points in 2000, the year she won gold for Great Britain in Sydney, so Ennis’ 6,906 may well be a sign of things to come. Ennis, the 2009 world champion, is by no means a shoo-in: she couldn’t retain her crown at the 2011 worlds, losing out to her great rival, the Russian Tatyana Chernova. While Ennis bested Chernova in five of the seven events, her eventual defeat was mainly due to being soundly beaten in the javelin, considered to be her weakest discipline. But if everything clicks into place in London, Ennis might just end up being the face of the Games.
