I started on the training for the 2008 race, however after 2 sessions, the Global Challenge business folded due to lack of a headline sponsor (it had previously been BT).
In your training manual the first page has the perfect quote.. "There is a tide in the affairs of men. Which, taken at the flood, leads on to fortune; Omitted, all the voyage of their life Is bound in shallows and in miseries. On such a full sea are we now afloat, And we must take the current when it serves, Or lose our ventures. "
I'm not into cheesy inspirational posters, but this is the only one on my wall.
