Sean Andrish gets bonus time.

As with all VHTRC Events, there is no fee to run. You will get a confirmation once you’ve entered that you are on the Official Entrants list. If the run is full, please email the RD to ask to be put on the ‘waitlist’.
Expect an email reminder 2 weeks from run day, then an email run week and a final email on Friday before the run.


Mostly trail, with a couple of miles on dirt along the canal, and a mile or two of pavement. The route begins at Peirce Mill in Rock Creek Park 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.

Pre-run Briefing

Climbing up over the Potomac River.

Check-in is required of all runners prior to the start. There will be a volunteer there with clipboard to ensure that everyone registered is accounted for. Pre-run briefing at 7:50 A.M. at the start line. Finishers of any distance should be sure to checkin and report they are done at the same place where they checked in pre-run.

Post run party

The post run party will include plenty of food and refreshments! You will want to plan to spend some time after your run enjoying the hospitality of the VHTRC.


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 be patient in the final tabulation of the results as there is a lot of jockeying that happens with the ‘bonus’ points.
To help in this, please ensure that each aid station has marked you down and marked that you have done whatever is needed to earn your appropriate ‘Bonus’ points. And while we know you have just set a new 50k PR, and you will be basking in your sub-4 hour time, do remember that at the end of the day, this is a Fun run and more a chance to get out on the trails with friends, test those legs out at a longer distance or an excuse to get outside! Thanks!

Potomac Heritage 50 km 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, where it continued to flourish. The event has continued on since Kerry’s move out West with current RD “White House” Tom McNulty, with two subsequent changes in location for the host site; as of 2021 the start/finish location has been at Peirce Mill in Rock Creek Park. See the former PHT 50km page.

Club Event Participant Medical Policy

This is an event with very real risks to your well being. The VHTRC does not provide medical care for runners at this event. Runners are responsible for their own health, safety, and well being at this event. No doctors, nurses, or emergency medical technicians, or anyone with any medical training are available along the course, at any aid station, or at the finish. The club does not supply any medical goods or services, including bandages, splints, antiseptic, or Ibuprofen or any other drugs to maintain the health of runners. Physical, medical, and emergency care is the runners' responsibility. In case of an emergency, we will endeavor to get local emergency personnel to an injured runner as soon as possible. Since most of our events are in remote areas, medical care may be far away in distance or time. Each year, runners finish — or are forced to drop out — with scrapes, deep cuts, hematomas, dislocations, and sprains. Runners have experienced cuts, bruises, bee stings, and asthma attacks. This is an event with very real risks.
