I am riding the London to Brighton for MSF (Doctors Without Borders) in memory of my dear friend Nic.

Nicolas Peissel was an emergency manager for MSF, helping deliver lifesaving aid in conflict zones around the world.

In 2001, I was on a cycling expedition with four others when I met Nic in a bar in Beijing. We quickly hit it off and within a few hours he had asked to join our adventure, eventually riding with us as far as Laos. Nic had a generosity of spirit, a sense of fun and was a joy to be around. When he died from a brain tumour last year, the world felt a poorer place.

Please help me to raise money for MSF's lifesaving work in Nic's honour, for the charity he loved and in memory of our time riding together.
