See those specs making their way to the peak of #CrestedButteMountain? Those are runners competing in the #DiscretePeakSeries on Saturday. Would you do it? Run on the edge over boulders and rocks through a scree field after running 5 miles up 3k ft and then run 5 more back down? They did, and they crushed it.
