20.7 miles.
What it took: 3100 calories, 7lbs of fluid loss, 3 hours, 21 minutes,
a good deal of sole, 2 energy bars, 1 32oz bottle of Gatorade, 2 glasses of water and 3 hits at random water fountains en route.
What it gave: See above.
I'm stoked. Tired, but stoked. No running for the next two days.
