Radcliffe has said it will be a 'race against time' to be fit for Beijing
Paula Radcliffe will join up with her British team-mates at the Olympic training camp in Macau on Sunday.
The news offers new hope that the marathon world record-holder will be fit for the Beijing Games next month.
The 34-year-old, who was diagnosed with a stress fracture to her left femur in May, has been training at high intensity in the past fortnight.
UK Athletics performance director Dave Collins welcomed the news saying: "I'm glad Paula's flying out on Sunday."
He added: "I'm sure she will have been maintaining her professionalism in training."
Radcliffe returned to her training base in the French Pyrenees after an MRI scan two weeks ago revealed she was recovering well.
The Bedford-born runner began her recuperation from her ill-timed thigh injury by cross-training and swimming before gradually returning to running.
It is not known whether the 34-year-old is fit enough to contest the rigours of a marathon in the expected humid conditions in Beijing.
But Radcliffe's decision to fly out to the holding camp means she will receive treatment and advice from British experts before making a final decision whether to line up for the marathon on 17 August.
She had turned her focus to Beijing after her dramatic failure at the 2004 Games in Athens in both the marathon and the 10,000m.
Her season has already been disrupted by a toe injury, which came to light after she finished second in the Great North Run last September.
Radcliffe won the New York Marathon last November despite the problem but it flared up again during altitude training in the USA in February, and she was forced to miss the chance to earn a fourth Flora London Marathon title in April.
Hayley Haining remains on standby to run in the marathon on 17 August, alongside Liz Yelling and Mara Yamauchi, should Radcliffe fail to make it.
