Name your challenge!
Can you run 100 of the gnarliest kilometers of the Mason-Dixon Trail in between sunrise and sunset on the Saturday near the longest day of the year? We'll write your name on this website if you do.

A. The Jeremiah Dixon 5000 Chain Traverse: Run self supported without a crew or pacers. Carry your own provisions and use food, drink, and ice at our picnic grounds and water drops, but no other external assistance. This is for the hardcore. Dixon had to drag miles of chain (80 links per mile) along the PA-MD border. Be like him and drag your own britches the 60+ miles without much help.

B. The Charles Mason Celestial Passage: Use whatever crew or pacers you like. Mason needed a lot of help with his astronomical equipment while surveying the border. You want help, too? That's OK. It's tough even with lots of help!

For either challenge:
  • The Original Sunrise-to-Sunset option (05:34 to 20:35 - total time 15:01)
  • Civil twilight option: (05:05 to 21:12- total time: 16:06)
  • Nautical twilight option: (4:24 to 21:54 - total time: 17:29)
  • Astronomical twilight (3:36 to 22:42 - total time: 19:04)

The Picnic: Your Trail Dawg friends will be hanging out with drinks and munchies at Cold Cabin Park, Lock 12 Interpretive Area, and Otter Creek Campground, cheering on those brave enough to attempt the challenge!

2013 Picnic Directors: Hunt Bartine, RD (hbartine@yahoo.com); Pete McLaughlin, Deputy (mclaughlin.pete@gmail.com).

How to Enter: This run is a Trail Dawg running party. It is a personal challenge and celebration of trail running for our friends, not a race. It is a free individual effort, and not to be considered an organized, sponsored or affiliated endeavor; no applications, fees, releases, etc. And, as this is not a real event, remember that your Trail Dawg pals are just there to cheer on individual runners brave enough to try to do this, and to record your name for posterity on our web page if you succeed. Nothing more. You're responsible for your own foolish decision to try to run this route. Don't expect much more from it other than self-fulfillment. You would have more fun picnicking with us than trying to run 62 miles on a hot day. 

For your own darned good, if you are going to try this, you should be able to document completion of a 50 mile or longer race in the last two years at a reasonable speed -- or to convince us you know this trail really well. We're limiting recognition to **25** runners, but anyone can join us for the picnic and run some sections of the trail! First dibs were given to previous participants so recognized openings for "The Challenge" are very limited. 

That said, email one of the Picnic Directors if interested in an invite.

Email group: When you enter MDLD, we'll add you to the email group list so you can chat with other runners about logistics and trail lore.

Aid and Run Support: None. We're busy having a picnic and you want us to help you? OK, actually we'll be there to cheer you on and hope you'll meet us at our picnic stops to enjoy the food and cold drinks! Some of us think it is fun to make fun of fools trying to run 100K on a hot day while we picnic. Feel free to share your favorite goodies. We'll also stash water at several places along the trail so we can be sure none of our friends get dangerously thirsty. Please see the Water Drops page for locations. However, please plan to be self-sufficient and carry essential supplies with you. 

Transportation: This a point-to-point run. You're responsible for coordinating your own transportation. However, it's been easy most previous years for most runners to coordinate car drops with other runners. The MDLD email group is a good way to communicate with fellow runners about this.

Trail Markings: Mason Dixon Blue Blazes and good sense of direction. Interested runners should purchase a set of the maps published by the Mason-Dixon Trail Association and carry them. This run's challenge includes the not-always-easy task of following the course blazes and remaining on the Mason Dixon Trail.
