Best wishes on your journey. You're out there right now!!
As far as I know the women's FKT is about 16:42 which I ran on 12/10/2006. See Howard Cohen's post above. He ran with me all day and, after screaming down Ray Miller, finished about 5 minutes ahead in 16:37. This was not an all-out effort but a training run.
Let us know how it went!
