here are my guesses:
3:12:17 - not peeing
4:04:36 - falling on face
that was a fun game, thanks. :) still marveling at your run, bro!
Good guesses! You got the try to pee spot ... the fall on face is more subtle, and much earlier in the race. 4:04 was the last aid station, where I foolishly stopped too long. ;)
