You all know by now that I'm something of an environmental campaigner. This is a chance for me to do a bit more for one of my favourite charities, Greenpeace, than simply send a few emails. Just think, your pennies may help them upset George Osborne even more, and that can only be a good thing. More seriously, events like Hurricane Sandy, the drought in the US breadbasket leading to food prices going up, and ever-more floods in the UK are salient reminders that climate change is already causing a problem on a global scale.

It is only a 10K - not the furthest I've ever run - but this time I will have the impediment of running dressed as Father Christmas. It isn't clear whether they'll be supplying the obligatory belly, so just in case I am cultivating one of my own :) I'm not expecting big donations here - a fiver is plenty. I said that if you helped me reach my original target of £200 I would personally put in a further £50 myself. We've gone past that, so if I reach £400, then I will put in £100 of my own for all to see. How's that for a deal?

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.

So please dig deep and donate now.
