On September 8th I'm going to walk nine miles from the top of my street in Cambridge to Chittering in Cambridgeshire. Will I survive walking without an experienced navigator or a reliable 3G signal? Will I slip out of exhaustion and fall into the Cam? Will I ever make it home to Molly? The only way to find out is to sponsor me, as much or as little as you can, before I set out in one month's time.
