I've just completed Trailwalker 2008. (Google it if you've never heard of it). 100km of hard bloody graft. My team did it in 27 hrs. Gukha Log did it in 10hrs. Awesome. I have to put on record the bloody fantastic organisation of the event by the Gurkhas. They smiled, they applauded, the marshalled, they encouraged - and their teams beat the cr*p out of everybody else.
