Jessica Ennis was beginning her bid for Olympic heptathlon gold this morning convinced she could be no better prepared for the biggest two days of her sporting life.
The 26-year-old from Sheffield was kept out of the 2008 Beijing Games by injury but is physically at her peak in London.
Asked at UK Athletics' recent training camp in Portugal if she was in the best shape of her life, Ennis said: "I do feel very good to be honest. I am very happy with the year so far, what I have done."
She added: "It feels great because all through the year you worry a bit through every training session. You cannot stress too much but you are thinking 'What if I clip a hurdle', or something happens and it can go just like that, so yes it feels good to be this close and still feeling good."
The first test was over the 100 metres hurdles this morning, but Ennis is a world-class performer in that event in her own right so it presented an opportunity to make the perfect start.
Ennis may have lost her indoor pentathlon and outdoor heptathlon world titles, but in May she bounced back in brilliant style with a new personal best and national heptathlon record of 6,906 points in Gotzis, Austria.
That put her 75 points ahead of the previous record of 6,831 set by Denise Lewis in 2000, shortly before she won Olympic gold in Sydney, and makes Ennis only the eighth woman ever to score more than 6,900.
Barring stunning results in the men's shot final and women's 10,000m final on Friday evening, Ennis will be expected to collect Britain's first athletics medal tomorrow night, some 25 minutes before Mo Farah also goes for gold in the final of the 10,000m.
"It is nice being on at the beginning," Ennis added. "I much prefer to get it out of the way and it would be great to get us off to a good start and having Mo on straight after."
The high jump follows the hurdles this morning, with the shot put and 200m this evening, before the long jump, javelin and 800m take place tomorrow.
