Entry to the 2019 race opened on Monday September 2nd, and closed in a week (the cap of 110 was reached on Monday September 9th). For 2019 the PB&J 50k runners saw a slightly altered course and a NEW start/finish location within Prince William Forest Park. There was no wait list for the race.

If you are not running and would like to participate, volunteers are eagerly sought! Scroll down for details and contact information.**

For those wondering how quickly the race may hit its limit of 110, the sign up for the 2018 race opened on August 31st and it closed at that 110 runner cap on September 11th. In 2019 it closed after a week.

The 6th annual running of the PB&J 50K Fat Ass race is scheduled to be held on the trails in Prince William Forest Park on Saturday October 3, 2020. The start/finish area is at the Telegraph Road Pavilion, located a short distance past the park’s visitor center, within a half mile of the entrance to the park off of Joplin Road near I-95.

See the updated course map (course is highlighted in bright green), as well as the old map in case that is of interest Turn Sheet and Course Sketch Map. See also the Prince William Forest Park trail map.

For those of you who have raced at the pre-2019 iterations of this 50k, virtually all of the loop portion of the course on the far side of the suspension bridge from the start/finish area is the same as it was in previous editions of the PB&J. What changed is the approach to that landmark bridge from the start, and then the return from the bridge to the finish of each loop. The singular change on the loop portion of the course is the location of the Mawavi Road aid station, which moved down to the point where the South Valley Trail crosses that gravel road. This eliminated the out-n-back climb to the aid station on each loop.

Why the “PB&J 50K”? The name of the race is an homage to the late, great training run series hosted on local NoVa trails by Toni Aurilio and Jo Leigh Lockner. The intent of this event is not only to provide an organized 50km race on a relatively easy course in the DC area, but also to provide a great training run opportunity on some rolling, non-technical trails. We anticipate that many runners prepping for one or more of the Mid-Atlantic area’s November 50 milers may find the PB&J to be excellent prep.

How Do I Play?

Enter using the VHTRC’s online signup — keep reading and scrolling for the link, once it is posted!
There is no formal entry fee - this is a “Fat Ass” event.
That said, you will be assigned a “tribute” item to bring for common aid.
You will need to pay the park entrance fee ($10 per vehicle) at the Visitor’s Center at Pine Grove. If you have a National Park pass, you can display that in lieu of making day visitor payment.

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.
