I ran the entire length of Paria Canyon from Wire Pass to Lees Ferry yesterday, saturday january 13th 2018.
It was about 44 miles, and I did it in 10hours10 min exactly. I spent 2h30min to reach Paria confluence, and 7h40min from confluence to Lees Ferry, including 4 hours in the dark.
I started the activity at 11:33 am, and reached Lees Ferry road at 9:43pm, and the activity logged is available here: www.strava.com/activities/1357174504
I also made a video about it, available here: www.youtube.com/channel/UCWXLP-S5B0qEYqTVRcQSjYQ/videos
I believe this time is easily beatable by any ultra runner, since I was slower compared to Jay Aldous performance, due to exhaustion, and running in the dark.
I hope this reference could help others to tackle this run, it was a great adventure .
