British athlete Perri Shakes-Drayton concedes her best chance of Olympic glory may not come at the stadium she grew up so close to.
Shakes-Drayton sprang to prominence in the European Championships in Barcelona in 2010, winning bronze in the 400 metres hurdles and adding another in the 4x400m relay.
"I've never had in my thoughts that I'm going to get a medal come 2012, maybe four years after is more my time," said Londoner Shakes-Drayton.
Her performance in Barcelona led to high expectations for the 23-year-old from Bow, east London, but she has struggled to build on that success since. Her time of 54.18 seconds in Barcelona remains her personal best, while her quickest time of 55.25secs this season leaves her 21st in the world and behind British team-mate Eilidh Child.
"A lot of people were saying 'going for gold medal potential' but everyone is going out there trying to get a medal. It's not going to be easy," Shakes-Drayton added ahead of this weekend's London Grand Prix at Crystal Palace.
Asked what would satisfy her in London, she added: "Making it to the final and running a PB. Then I will be over the moon."
Perhaps a better chance of a medal will come in the 4x400m relay, with Shakes-Drayton anchoring the British quartet to a surprise gold at the World Indoors in Istanbul in March.
"We have a very good team," added Shakes-Drayton, who missed out on selection for the last Olympics despite winning the trials. Tasha Danvers was chosen instead and won bronze in Beijing.
"I don't know about winning but we are definitely capable of a medal. It's not going to be easy just getting into the quartet. Everyone is going to step up their game and no one is just going to give it to you, we all have that fighting spirit."
Shakes-Drayton held off individual champion Sanya Richards-Ross on the last leg in Istanbul and would love the chance to do so again in London, and she joked: "I'm going to run like a dog's chasing me!"
