I lowered the female FKT for the Zion Traverse yesterday, running it in 8:32. Self-supported run east to west stashing water at West Rim and Hop Valley THs. My husband, Ben Lewis, ran with me from The Grotto onward. Carried a GPS watch with us and took lots of video for verification (will upload these soon via Ben's blog, http://ben-runlong.blogspot.com/2013/04/trans-zion-female-fkt-and-bosho-marathon.html). Details in brief: hit The Grotto in 1h40, West Rim TH in 4h29, Hop Valley TH in around 6h, and Lee's Pass in 8h32.
Oh, and thanks to our fabulous sponsor CPT[TM] for all their support.
