Marcus - a few words of advice, if I may: before you start off again there are two Ps that are well worth considering.

The second is Pacing: 40km was not a sensible distance for your first day.
Not that I'm trying to discourage you. But just bear in mind that old climbing adage: the challenge is to you, not to the mountain.
