I Googled it and found some old results. Huh, looks like it just started in 2011. Checked out how many participants there were and their finishing times—only a handful, no one I knew, and man it takes a long time to run 100 miles. There was a 50-miler, too, but of course then you don't get to run from Yellowstone Park to the foot of the Grand Tetons.
|Downhill all the way.|
THEN I realized I was doing all this curiosity-satisfying with an enormous grin on my face. How stupid is that? I don't even run anymore.
