Up and down the NE Ridge, starting and ending at the Halfmoon Creek TH.
Leave CO Trail - 12:40
Treeline - 34:40
Summit - 1:11:58
Treeline - 1:26:50
Colorado Trail - 1:36:30
TH - 1:42:55
On 7/8/2012 I ran from trailhead to summit in 1:11:37 (a personal best), but I think Kilian Jornet has done this ascent in 1:08? Not sure. On this run I left the CO Trail at 12:15 and hit treeline at 34:15.
