Goldie Sayers is hoping her best will this time be enough for an Olympic medal having been cruelly denied a podium place in 2008.
The British number one is heading for her third Games after sealing a 10th successive national title at the Aviva Trials in Birmingham on Sunday and will continue her build up at this week's European Championships in Helsinki.
Sayers agonisingly missed out on bronze by just 38cm in Beijing four years ago despite breaking the British record with a throw of 65.75m and feels she'll probably need to surpass that mark to achieve success in London.
The 29-year-old appears in good shape to do just that after managing an effort of 64.73m in Rome last month - her best since the last Olympics - although she was disappointed not to have thrown further than 58.45m in Birmingham.
"I'm in good shape despite not really showing it at the Trials," said Sayers. "The conditions weren't easy and the wind literally turned round as soon as we finished.
"There's still lots to do but there's no reason why I can't do what I did last time.
"From experience you can't just say you're going to win a medal because you just have no idea what other athletes are going to do.
"I thought what I threw last time would be enough for a medal and it would have been at any other Olympics. But it wasn't. You've just got to aim at what you can control and that's me.
"I'd like to think this is my time. I can't say I'm not experienced enough and I think there'll definitely be a higher level of excitement about this one. Having the home crowd is certainly something that can help us all."
Sayers has always wished the domestic competition was more testing but was still able to enjoy Sunday's milestone victory.
She said: "When I woke up on the morning of the event, it made me reflect on previous trials as it is a significant milestone. It's made me think of where I've come from and where I am now.
"At my first Olympic trials I needed the 'A' standard and managed it with my last throw, which was really exciting. I only had an outside chance of going as I was really young then.
"The second time it was just about getting the job done and although this one was similar, it was special because of where the Games is.
"Even though the competition in this country isn't very strong, you want to put on a good display for the crowd."
