Most excellent.
Saving the tough climbs for last is Satanic. We have a local century like that (OKHT) and I don't see myself ever doing it, because I'm a wuss.
As far as walking is concerned, it slows you down and expends valuable energy. I hate doing it, but it still counts, and I still do it.
One little critique: after reading this entire thread I don't even know what state this event is in. Yes, I can google it (I intend to) but a report should include locale and maybe a photo or two.
And expression of existential angst always works for me.
