I was also at the talk he gave in York - wasn't he brilliant? - and because he was staying overnight with a friend was able to meet him briefly. A true humanitarian and a great inspiration. I was fascinated by the story of his life as caballo blanco the 'white horse' in Chris McDougall's book Born to Run, and his love of the Tarahumara people of the Copper Canyons.
