Rio Olympics 2016: Emotional Jessica Ennis-Hill admits she may retire after taking heptathlon silver for Team GB

JESSICA ENNIS-HILL is certain that Olympic silver in Rio ended her last ever heptathlon.

Ennis-Hill wiped away tears after losing her  title to Belgium's Nafissatou Thiam on Saturday by a slim margin.

At first she called them "happy tears" because it's another medal, but then acknowledged how hard it was going to be to give up and just how close she was to doing that.

She said: "I think it's a mix of thinking back to the last few years. I'm just so emotional and, yeah, I've just got to make a decision as to whether this is my last heptathlon or not. I'm so proud of what I've achieved the last few years. I've got to have a think."

Judging by the emotion, it looks like it will end in Rio de Janeiro.

She looks back on two world titles, and of course the delight of that Olympic gold medal four years ago at her home games in London, when she, Mo Farah and Greg Rutherford delivered three golds for the home fans on what became known as Super Saturday.

Farah retained his 10,000 meters title on Saturday in Rio, but Ennis-Hill had silver and Rutherford took bronze in the long jump.

"It would have been incredible (to all win gold again) and that was a really tall ask for all of us. But we've all produced medals again four years down the line."

The 30-year-old Ennis-Hill, now a mother to two-year-old Reggie, missed out on retaining her title by around three seconds in the final event. Ennis-Hill needed to beat Thiam by ten seconds in the 800 meters to clinch the gold.

Ennis added: "I was like 'oh god that's so much.’ But I just thought, I'm going to run hard like I always do."
