Jessica Ennis feels it is the little things which will make the biggest difference in her quest for Olympic heptathlon gold.
The Sheffield athlete, 26, heads out to the IAAF World Indoor Championships in Istanbul on the back of an impressive performance from the recent Aviva Grand Prix in Birmingham, where she ran the fastest time this year for the 60 metres hurdles and set a personal best of 6.47 metres in the long jump.
She said: "The Olympics is that one moment you train so hard for all those years. You have to make sure you are in great shape, are injury free and ready to compete to the best of your ability."
Ennis may have surrendered her world crown to Russia's Tatyana Chernova in Daegu last summer, but the Briton is in no doubt that by the time all eyes are on London, she will have done everything possible to give herself that winning edge.
"Training has been going well, so have the competitions, so I am looking forward to heading out to the world indoors and hoping I can raise my game a bit more and perform well out there," said Ennis at the launch the new Powerade Olympic Games Sports Bottle, which will be used to hydrate the athletes at the London 2012 Olympic and Paralympic Games.
"I think it is going to be quite small margins and key events which I need to make sure I get right. Doing those will hopefully gather me a few more points."
Ennis told Press Association Sport: "I have kind of put Daegu to the back of my mind, to be honest. That year is done with - if I had won last year, by now I would have already put it behind me. I have to just focus on what I have got to do this year."
Ennis will go head to head with Chernova in Turkey for the first time since having to settle for World Championship silver.
The British athlete, though, feels the competition is positive and added: "Every year you have a rivalry with someone, whether it is domestic or international, someone ups their game and things change.
"I don't see it as just a rivalry between me and Chernova, there are a few other girls who are performing well and have done in the past, so I see it as a battle between all of us."
