Great Britain's Jessica Ennis has admitted that she needs to learn if she is to win gold at the Olympic Games later this year.
The 26-year-old followed up her heptathlon silver medal at the world championships in Daegu last year with another second-place finish in the pentathlon at an indoor event in Istanbul yesterday afternoon.
Despite admitting that she was happy with her two-medal haul, Ennis has confessed that improvements are needed if she is to go one better in London.
"I need to make sure I learn from these experiences, get it right and turn silver into gold this summer," she said. "I am happy because two silver medals at world champs is great, but I would have loved to have won a gold medal.
"There's disappointment because I wanted to come here and retain my title, but I had some good performances today.
"I believe things happen for a reason and hopefully that reason is going to become clear later on in the year."
Ennis has never competed at an Olympic Games.
