If you haven't ever heard of "chammy cream" you will hear about it a lot more from me over the coming weeks. This is because I am doing something horrid and hard to support a worthy cause.

Also, I genuinely don't know if I will be able to do it, which frightens and intrigues me, as I don't want to let anyone down.

Over 400km, over 5000m of climbing. From the wrong side of the Pennines to the right one. Please donate generously.
