I AM writing to ask your readers to join Cancer Research UK and take on the challenge of a lifetime, to really make 2003 a year to remember.

We are looking for 300 people to take part in "Trek For Life", a special ten-day journey to the Great Wall of China, during Breast Cancer Awareness Month in October.

The charity is hoping to raise £1 million from the event to go towards its pioneering breast cancer research programme.

Anyone over 18 can join the trek, no matter how unfit you think you may be!

All you need do is pay a small registration fee and pledge to fund-raise a minimum amount of money to Cancer Research UK.

So, if you've always dreamed of visiting one of the ancient wonders of the world, want to have the experience of a lifetime, and are keen to raise funds for a life-saving cause, take the plunge now and sign up for Trek for Life.

Just call the team on 0870 606 0016, email ultimatechallenge @cancer.org.uk or check out www.cancerresearchuk.org/ultimatechallenge.
