Chew, ditto re finishing. CheifP, I've done a lot of endurance events over the years (although this is more extreme than most) and I'd say that there's often very little pleasure during the event, but there's immense satisfaction to be gained from trying your hardest to complete. Life is quite comfy most of the time, to be forced well outside of your comfort zone is no bad thing. I cannot, in all honesty, say that I'm confident about my ability to complete the event, but I am prepared to try my hardest……….do you think think they'll give me a jersey for effort?
