SIR - I am writing to wish Andrew Raynor the best of luck in the London Marathon on Sunday.

Andrew, from Otley, is running to raise as much money as possible for World Cancer Research Fund's research and education programmes.

I would urge everyone in the area to show their support for him by sponsoring him as he raises funds for what is a really worthwhile cause.

You can sponsor Andrew online via WCRF's secure website at wcrf-uk.org/lm or by calling (0207) 3434205.

Teresa Nightingale, Head of Fundraising, World Cancer Research Fund, Harley Street, London
