Zwanzig!

With the disclaimer that this was not a high-quality 20. About 5 1/2 hours - could have been better, but I hit The Wall (with a resounding "thunk") at around 17 miles, and probably took about 40-45 minutes to slog in the last two miles. Still, I'll take it.

Body Glide would have been a good idea for this one, as it turns out. I put on a couple of bandaids, but the suckers came off somewhere around the 13 mile mark, with predictable results for my poor shirt.
