Jessica Ennis-Hill: I will make retirement decision after Rio
Heptathlon world champion Jessica Ennis-Hill has said she will wait until after the Rio Olympics to make a decision about her retirement.
She will head to the 2016 Games as favourite to defend her Olympic gold medal after winning a second World title in August.
And she could prolong her career and bow out at the 2017 World Athletics Championships in London.
Ennis-Hill, 29, told BBC Sport: "I'll see how my body holds up."
She added: "My focus is on Rio at the moment and they will be my last Olympics as I'll definitely be too old by 2020.
"I want to enjoy this next year and make the most of it and make a decision on my future after Rio."
Ennis-Hill, mum to toddler Reggie, said she would like to have more children once she retires.
And she rejected claims she was a "super mum" after winning the world title 13 months after giving birth.
"It is a huge honour but there are so many incredible mums out there," Ennis-Hill said.
"I feel so lucky that I can train every day and do a sport that I love and to have had the opportunities and experiences I have had."
She was speaking after winning the Sunday Times and Sky Sports Sportswoman of the Year award for a second time and believed the unexpected gold in Beijing did not put more pressure on her Rio prospects.
"I'm so happy with the way I've come back into my career in athletics. I will be competitive [in Rio] and I do want to do as well as I can possibly do," she added.
