The Appalachian Trail runs about 96 miles through Shenandoah National Park, from Rockfish Gap to Compton Gap, and the route has generated some FKT interest. Matt Kirk ran it in 23h20m, but his trip report appears to no longer be on a public website. Sue Johnston also ran this route in April 2012, as reported on her blog http://runsuerun.blogspot.com/2012/04/at-thru-shenandoah-national-park-in-one.html?m=0 but she did not report at time.
I will be attempting an FKT on the AT through Shenandoah National Park starting Thursday, August 8. I will go south to north. Since it is a bit difficult to define the southern terminus of the AT in SNP, I will start at Rockfish Gap, and record "start" times at both Rockfish Gap and McCormack Gap (where the AT exits Bear Den Mountain). Northern terminus will be just north of the Compton Gap Trail at Chester Gap. This will be a supported attempt, as I will have crew meet me at several parking lots along Skyline Drive. I will try to record time and distance using my GPS (as long as battery lasts), as well as my watch.
Oops - wrong date - starting Thursday Aug 9 :)
