The British gold medal hope insisted she will run providing she avoids a setback in her recovery from her thigh injury.
"I'm racing unless my leg breaks down," said Davenham-born Radcliffe, 34, who had looked destined to miss out on her fourth consecutive Olympics when an MRI scan in May revealed a stress fracture in her left thigh.
The marathon world record holder has defied medical opinion so far and linked up with the British squad at their Macau training base on Monday.
Radcliffe will now begin the last few steps towards realising her ambition of an Olympic gold, her main remaining goal in a highly successful athletics career.
