On March 20, 2011, the last day of winter and before the equinox (which was 2300 GMT), I ran up and down Pikes Peak from the Barr TH in moonlight. A night run was was required on the route I used in order not to interfere with other multiple users of the mountain. My times were 3:13:47 to the summit, 1:55:25 back to Barr Trailhead, for a 5:09:12 overall.
I'm from Utah, where the winter rules are anything goes from TH to summit: trails, routes, avy paths, whatever. I understand that in Colorado there may be "timberline" rules, but in my view that gets too complicated. TH to summit and back, don't break yourself or any tender plants or cause erosion, be nice, be considerate, be respectful of others' rights on the mountain, and you're good to hook.
So, maybe my record gets some time of asterisk entry--dunno. Anyway, it is what it is, and it was a great moonlight jaunt. 18.15 miles total.
