Hello, I've decided - impulsively and ill-advisedly - to join in a charity run through Greenwich, dressed as Santa, on December 6th. I can't back out, so now I need your help.

I'll be running (extremely slowly) for The Food Chain. They're a charity that delivers meals, groceries and other important stuff to people who are chronically sick with HIV-related illnesses. This year, TFC want to supply these people with a Christmas dinner - but they need £3,300 to make that happen. The money I raise will go directly into that fund.

So by sponsoring me to stumble around with a lot of hungover Santas on a freezing Sunday morning, you'll be doing your bit to give something nice to somebody who really needs it. It's a win-win, so please dig deep and give what you can.

Cheers.
