Entry: Please read the details below prior to entry into this event.  The link to join the entrants list will be posted near the bottom of this page, once entry does open.  So you will find it after you have read the details, and hopefully then have a better understanding of the event you are entering! 

Entry is limited to 60.    

Course: Mostly trail, with a couple of miles on dirt along the canal, and a mile or two of pavement. The route begins in DC, crosses over the Key Bridge into Virginia, continues on single track up to the Beltway, then returns to DC over the Chain Bridge. 

Markings: Trail will be marked in DC with flour/chalk. In VA, you will follow blue blazes, with the exception of the detour to the Turkey Run Aid station. This portion will be marked with flour/chalk.

Pre-run Briefing: Check-in required of all runners prior to the start. Check-in, which include issuance of a runner number, will happen race morning. Pre-run briefing at 7:45 A.M. at the start line.  Finishers should self-report times and distances (legibly!) at the same place where they checked in pre-race.

Results: Results will be posted, but will not be reported to Ultrarunning Magazine or any other publication. Check the results from previous years to get a sense of why that is the case. Please enter your finishing time on the sign-in sheet at the finish; this sheet will be at the same spot where you checked in on race morning.  And while we know you have just set a new 50k PR, and you must be exhausted, do what you can to make your finishing time (and any accompanying notes) legible!  Thanks.

Post Race: Join us for the post race party afterward; it will again include the Japanese Kabocha Squash Curry, Steamed Rice, lots of pickled additions and furikake condiments and plenty of refreshments. Stay afterward for the wonderful Mt. Pleasant Lantern walk. 

Sounds like fun and still want to do it?

Entry is now CLOSED

Questions: Contact Thomas McNulty RD. To see if you are entered, check the entrants list.

Potomac Heritage 50km History

One of many stream crossings on the PHT

 The Potomac Heritage 50km was created by Jeanne Christie and Larry DeHof. Larry was the RD for many years. When Jeanne and Larry left for Maine, Kerry Owens took over the event in 2003 and gave it a new start/finish. The event continues on with new RD Thomas McNulty. Former PHT 50km page
