Ennis pulls out of indoor season
Olympic heptathlon champion Jessica Ennis will not compete during this year's indoor athletics season as she focuses on her preparations for the IAAF Athletics World Championships in Moscow in August.
Ennis won the world title in Berlin in 2009 but claimed silver in Daegu two years later as Russia's Tatyana Chernova triumphed.
Having toyed with the idea of switching her attention to the 100m hurdles following her Olympic victory, Ennis has now set her sights on the 7000-point barrier, a mark reached just once in the past 20 years.
"After the incredible high of the Olympics and the post Games celebrations I went back into tough winter training with an open mind on whether or not I would want to compete indoors this year," Ennis said in a statement.
"Training has been going well but I feel that my focus really has to be attempting to win another world title in Russia this summer and not the short-term indoor season."
Ennis, who reached a personal-best 6955 points en route to victory at the London Olympics 2012, is expected to return to competition in Tallinn, Estonia, at the end of June.
The 27-year-old's Olympic performance was the best heptathlon score since Sweden's Carolina Kluft posted 7032 points at the 2007 World Championships in Osaka.
Jackie Joyner-Kersee of the United States set the current heptathlon best of 7291 at the Seoul Olympics in 1988.
