Jessica Ennis-Hill has said that successfully defending her Olympic title in Rio de Janeiro this summer would go down as one of her greatest achievements.

The 30-year-old memorably won heptathlon gold for Great Britain at the London 2012 Olympics, but in the intervening years she has taken time out to have a child as well as suffering from a number of injuries.

However, the two-time world champion was included in Team GB's 80-strong athletics squad for this summer, and she insists that she is "feeling good" with less than a month remaining before the Games.

"Everything's coming together now and I'm feeling good. Training over the past few weeks has been going really well and it's been good to be back in the competitive environment recently. There's still some time left before Rio to put some work in as well," she said in a statement.

"London was an incredible experience and the two journeys to London and Rio have been completely different, which I've really enjoyed. If I was able to defend my title in Rio it will certainly be one of my greatest achievements."

Ennis-Hill's fellow 'Super Saturday' medallists Mo Farah and Greg Rutherford have also been included in the squad.
