hitting the wall

Runners tell the tale (I only run when chased, by something larger and with sharper teeth than me)...of getting to the point in a marathon where they hit the wall...all the excitement and enthusiasm has given way to 3-second blinks and serious looks on faces. We have realized that we have but 4 hours left in this mapgiving...the music has faded and tasks are now being refined...the chorus of now is hushed voices, rapid mouse clicks, deep exhales, and Tanya's voice now conducting this murder of crows.
