While we’re the first official event to be held on this course, Mark Hartell established the fastest known time for the Backbone Trail of 12:09 on March 24th, 2012. He wrote about it in his blog; you can read all about it here.
Sue Johnston holds the women’s FKT of 16:42, set back-in-the day on December 10th, 2006 whilst casually conquering the course with Mr. Backbone Trail, Howard “H’ard” Cohen. She didn’t blog about it. She is modest. And fast.
