I'm running the Royal Parks Half Marathon in aid of St Mungo's, the homelessness charity, which in these straitened times is more vital than ever. Every penny you can give will be gratefully accepted.

Read a bit more about what St Mungo's do, and why I'm running for them, on my Telegraph blog.

Donating through JustGiving is simple, fast and totally secure. Your details are safe with JustGiving – they’ll never sell them on or send unwanted emails. Once you donate, they’ll send your money directly to the charity and make sure Gift Aid is reclaimed on every eligible donation by a UK taxpayer. So it’s the most efficient way to donate - I raise more, whilst saving time and cutting costs for the charity.

Thank you so much for contributing.
