I will be attempting to set the Self Supported FKT of the MDT the week of August 20. In doing so, I will also attempt to set the overall FKT for the trail as well. My actives can be followed on Instagram ( and Strava ( 


Self Supported-I will NOT have anyone following, or otherwise meeting me in prearranged manner to give me support. I plan to do this hike ... as a backpacker, carrying all of my food, equipment, and water [note that using natural water sources along the route is allowed] between resupply towns, which I will walk into and purchasing food, in these towns. ...I will not be getting in a vehicle for any reason during this attempt, if I do it means the attempt is off.

Hi all! My buddy Dustin and I will be doing a self-supported FKT attempt of the Mason-Dixon starting this Friday (Oct. 4th, 2019). We're excited to see the full length of this trail at what should be a nice time of year. 

We can be tracked via SPOT ( and, when in cell service, will throw some posts/photos/etc on twitter ( and possibly on IG (

Not my own runs, but I know he's too humble to ever submit them. Eddie Pantoja has knocked the Mason-Dixon Trail out of the park multiple times, setting FKTs for Supported and Unsupported runs.

I'll be attempting the self-supported FKT of the Mason-Dixon Trail.  I'll be leaving Whiskey Springs heading east this Thursday (5/20) about 8am.  Updates will be posted on Twitter (

I'm going to give the self-supported FKT another go.  Leaving Whiskey Springs Friday (10/8) morning.  Updates will be posted on Twitter (

The current Mason Dixon Trail map set (MDTS 2020-print, Map 7) says no foot traffic is allowed on the Route 40 Bridge (near Havre de Grace, MD) and advises people to catch the Teal Line Route 7 bus or a taxi across.

For safety, the FKT route for the Mason Dixon Trail acknowledges vehicle passage over the Route 40 Bridge section for all categories of attempt (unsupported, self-supported, and supported) as an exception to the normal standards that apply to those categories.

Will attempt an unsupported MDT FKT, starting on August 24th.
