The 11th annual PB&J trail run will be held in Prince William Forest Park on Saturday, Oct. 24, 2026. There are two competition distance options: a 50k (two loops) and a 25k (one loop). Choose your adventure! But please, only choose ONE adventure (i.e. don’t sign up for both competitions)!

Entry opens on the 15th of September. There is no formal entry fee - this is a “Fat Ass” event. That said, you will be asked to bring one aid station item as “tribute” for use in the common aid at the event.

Only a total of 110 runners will be participating. The competitions have filled to capacity most years, so keep an eye out for registration!

It’s a hidden gem with shaded, undulating trails, a refreshing creek, and swinging bridges. It offers a fair mix of smooth and technical trails - perfect for new and experienced runners alike.

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.

The name of the event is an homage to the late, great training run series hosted on local NoVa trails by Toni Becerra and Jo Leigh Lochner. The intent of this event is to provide an organized trail competition on a relatively easy course in the DC area, and also to provide a great supported training run opportunity on some rolling, non-technical trails.
