So I found this story, and I tell you, I wish it had been more detailed: http://www.msnbc.msn.com/id/32966748/ns/world_news-europe. I still have a few more questions.  Are they allowed to wear hiking boots?  Where do they sit if they need to take a break?  And above all, for goodness' sake, have they considered the consequences of losing their footing and falling on a sharp rock or tree branch?!?!?  I hope they pack a lot of sunscreen, bug spray and antiseptic!
