Northern Irish TV presenter Christine Bleakley is all set to embark on her challenge to water-ski across the English Channel for Sport Relief.
The One Show presenter will hang on at approximately 20mph for the entire choppy 22-mile stretch to France - across the world's busiest shipping lane.
Bleakley was due to make her attempt on Wednesday but was forced to postpone her bid due to forecasts of gale force winds.
But health and safety and weather officials have given her the go-ahead for an early morning send-off on Friday.
Organisers of the Thomson Sport Relief Water Ski Challenge said Bleakley aims to set off "first thing".
Temperatures will be a miserable 7C, organisers said, with the wind chill below freezing.
Newry-born Bleakley was moved to undertake the challenge following a trip to Uganda with Sport Relief in 2008, where she met young people who are living tough lives.
She said: "It's so easy to come home from a trip like that and forget about what you've seen and keep going about your everyday life.
"I didn't want to do that. I'll never forget the people that I met and I want to do something to help them."
