Marathon world record holder Paula Radcliffe is to join Britain's Olympic training camp in Macau next week in a further sign that despite injury problems she will compete in Beijing next month.

The British runner is battling against time to fully recover from a stress fracture of her femur that wrecked her early preparations for the Games.

But she has been back in training at high intensity in the past fortnight and has said she is determined to give herself every chance of running in the Olympics.

Radcliffe has returned to her training base in the French Pyrenees after an MRI scan a fortnight ago revealed she was recovering well.

Her agent Sian Masterson said: ‘She is going to head there (Macau) in the next week, depending on what day they decide to leave their training base at the moment.’

Radcliffe is determined to make the event in order to make amends for her Olympic heartache four years ago, when she pulled out of both marathon and 10,000 metres.

If she is not fit enough in time her place will go to Hayley Haining for the August 17 race, joining Liz Yelling and Mara Yamauchi.
