Christine Ohuruogu insists she will keep running despite having contemplated retirement.
Ohuruogu admitted she should feel proud of her silver medal but that it still hurt to lose her Olympic 400m crown. Ohuruogu ran a season's best 49.70sec, her third-fastest time ever, and was just 0.15sec behind winner Sanya Richards-Ross of the United States.
At a news conference after the race, Ohuruogu revealed she had harboured thoughts of retirement but had decided to keep racing. She said: "I love what I do. I know it's never easy and I do complain and gripe along the way but I think there is always an appetite to do sport. I have not run out of steam yet. I want to put together a solid run of two to three years."
The 28-year-old, who grew up in Stratford just a stone's throw from the Olympics Stadium, said Richards-Ross was a worthy winner.
Ohuruogu added: "I was stunned. I was heartbroken actually, I really was. To lose your title like that, it was tough. But Sanya's a worthy competitor and she ran a good race. Nobody ever wants to lose a title, so it was very difficult and hard not to let the emotion of wanting to win distract me from my race plan - but I think it did in the end.
"I should be happy with my day's work and lost my title to a worthy competitor, and I should be happy with silver considering the tough time I have had over the last four years.
"I should be proud of myself. Even though I was initially disappointed it was so uplifting to be in that stadium and have people so proud and it was quite emotional for me to be so close to my home. I'm really proud the way they came out and supported us in their thousands."
Ohuruogu had beaten Richards-Ross into third place in Beijing but the American was not to be defeated this time around. Even so, Ohuruogu recovered from sixth place on the bend to go past DeeDee Trotter just before the line.
Ohuruogu did go on a lap of honour at the end, adding: "I just wanted to go back and say thank you to all the people who've come up. They've really made these Games special.
"Everybody I've spoken to - non-British athletes - have all said what a great crowd we have and what a great atmosphere and it's really great that the whole country has got behind the London 2012 Games. They've all helped to make it the Games it is."
