BBC Sport - Jess Ennis-Hill looks back at her golden heptathlon career

'I couldn't see how I was going to be good at heptathlon'

Jessica Ennis-Hill is one of Great Britain's most successful athletes, having won three world heptathlon titles as well as Olympic gold at London 2012.

She initially trained to be a sprinter, until she was introduced to the multi-discipline heptathlon by her coach Toni Minichiello - despite her initial doubts.
