The 30-year-old confirmed she will skip the official Team GB holding camp in Belo Horizonte partly because of fears over the Zika virus, as first reported by Sportsmail.
Ennis-Hill has no plans to follow golfer Rory McIlroy in boycotting the Games altogether because of Zika. But she will train at an undisclosed training camp in Europe before flying to Brazil to meet up with the rest of the team just a few days before the defence of her title begins.
Already mother to one-year-old Reggie, she is worried about the potential health effects of the virus, which is spread by mosquitoes and can cause a serious disease of the nervous system and severe birth defects in unborn children.
‘I’m concerned, I want to have more children and I worry about Reggie all the time,’ said Ennis-Hill, who is competing in Germany this weekend in her first heptathlon since her World Championship gold last summer.
‘I have loved going to the holding camp with the team in the past,’ she added. ‘There’s the banter, nervous energy and you know how everyone’s feeling. But this year is completely different now I’m a mum.
‘I’m aware of everything that’s going on with Zika and if I went out to Brazil straightaway I would miss Reggie. It’s harder this year to leave him for any period of time because he’s so aware. Having him with me in the holding camp will make me more content and happy.’
In contrast to London 2012, where her entire immediate family were in the Olympic Stadium to cheer her on, Ennis-Hill will go it alone in Rio.
‘It’s strictly business,’ she said. ‘London was incredible, it was a great buzz but it is different now. It’s about making sure first and foremost that Reggie is safe. Even though I’ve got my business head on when I’m competing, I’m kind of going to be distracted thinking, “It’s 11pm, I’m about to do the 800m, but is he OK? Should he be asleep?” And I don’t want to be distracted because this is a once-in-a-lifetime opportunity and I want to make sure I do it right.’
Ennis-Hill also admitted to being broody after visiting her sister Carmel, who gave birth to a baby girl, Sara, on Sunday.
