Audio: Hear Christine
Bleakley speak of her preparation - and fear - ahead of her
waterski bid

Christine said she was inspired to take up the challenge
after visiting Uganda last year and meeting a family whose mother
had died of aids.

She said: "At the age of 13, the oldest daughter had become the
sole carer of herself and her five brothers and sisters, living in
a hut."

She's being trained by Professor Greg Whyte, who also
trained comedian David Walliams for his successful Channel swim,
also for Sport Relief, in July 2006.

People can support her challenge by donating via the Sport Relief
website.
