Britain's Paula Radcliffe is showing her customary determination as she battles to be fit for next month's Olympic Games.
The women's world marathon record holder was diagnosed with a stress fracture of the femur in May, and few held out much hope of her competing in Beijing.
Yet the latest news from her base in France is positive - she is running again and, according to her agent, training with "high intensity".
At the age of 34, and with injuries taking their toll, this is surely her last shot at Olympic glory, so you can't blame Paula for hoping against the odds that she can be fit for China.
But with less than a month to go before the Games begin, and with her event scheduled for 17 August, can Radcliffe really hope to add Olympic gold to her many achievements?
