The 21-year-old will then begin a strict training regime to be in top form for her race.

Experts say it is important that Emma gets over her jet lag before she starts training.

"Symptoms of jet lag include daytime fatigue, a reduction in physical performance and loss of concentration," said Tracy Gregory, senior nurse practitioner at Manchester Airport.

"Emma must allow at least one day for each time-zone she goes through to get over the jet lag properly."

The young cyclist plans to train for more than four hours a day in the run-up to her 25km points race on September 21.

"She will spend about two hours training on the road before practising speed on the track each afternoon," said dad John from the family home in Lower Peover.

Her training programme also means that Emma will be in bed by 9.30pm.

But Mr Davies said it would not be unusual for the girl who learned to ride a bike in Tatton Park when she was five.

She trains every day without fail.

"Last year she was in Australia for Christmas and trained for a few hours on Christmas Day before having dinner at Planet Hollywood," he said.

But Mr Davies said it was now a way of life for his daughter.

"She loves it," he said. "Most of her friends are professional cyclists too so there is no pressure to go out partying."

Emma and her friends will be allowed three days after their event to enjoy themselves in the Olympic village.

"They may go to bed later then," said Mr Davies.
