Walking 100km non-stop across the South Downs. Four otherwise sensible people will attempt something at the limit of human endurance for charity. Two of us completed it in 2014. We have also supported friends in other years. We love walking, and are unlikely to run out of things to talk about.

Please donate to Oxfam and The Gurka Charities; they both do amazing work at a time when the world needs all the help it can get. We know times are hard for everyone, and we will be very grateful for every penny donated.

In memory of our team leader in 2014, Jeff Zie. Much missed.
