I did the 31 mile run on my own (except for the company of my dog) and self-supported. I started on July 27th, 2014 from Worthen Meadows Reservoir TH at 8:35 am by taking the Sheep's Bridge Trail down to the Middle Fork of the Popo Agie. From there I ran up the Pinto Park Trail, took the Deep Creek Cutoff, and headed up to the summit from Deep Creek Lakes. I made it to the summit in 3 hours and 49 minutes.
On the way back down, I went towards Tayo Lake, back to the Middle Fork, and up and over Roaring Fork Pass back to Worthen Meadows for a grand total of 7 hours and 38 minutes.
I moved fairly fast on this run, but I spent a lot of time talking to backpackers and horsepackers, taking pictures, and generally enjoying a great day in the mountains. This time is obviously very beatable, but I figured someone in Wyoming needed to get an FKT on this monster of a mountain started. Get out there and beat my time.
Here is a link to my Movescount page for the stats (beware the elevation feature on my Suunto watch obviously does not work right, but the rest of the data seems accurate): Movescount - Gabe Joyes
