Yike!  
Hey, how long did it take you guys to walk it?  {I may have missed the time}.  How long before the sweepers came up behind people?  
 
I am soooo tempted to try this on my own at home and see if I can do it.  We've walked 7 miles but I am into walk/running it and then maybe moving up.  
Oh, I survived a 5k but I ran the whole thing {not fast, of course, but it was 'running' to me}.  
You guys are inspirational, definitely!!!
