Fall Backyard Burn Trail Running Series

The 21st annual Fall Backyard Burn (FBYB) Trail Running Series is a series of 5 and 10 mile trail running races held on some of the best trail networks in the Northern Virginia Area. All the courses include a mixture of forested fire roads, twisty hiking trails, stream crossings, grassy fields, and minimal pavement.

The Spring and Fall Series are both independent of each other. Race in one or all five races in the FBYB. After each race, awards are presented to the top five finishers in each age group. In addition, a point system adding competitors’ race point totals (see below) will be used to determine the top five series finishers in each age group. Series prizes and awards are presented at the final race of the FBYB series.

Take advantage of 10% savings by signing up for multiple races in the series at one time (10% off each race).

Laurel Hill

Laurel Hill
Lorton, VA

Located just south of the Capital Beltway in Lorton, this beautiful race course includes a mixture of forested and open meadow singletrack meandering through 1600 acres of the former prison grounds. The race starts and ends under the old guard towers at the Workhouse Arts Center, which is the site of the former Lorton Reformatory. The course is one of our least technical and most of it is on singletrack that is a mix of dirt and crushed stone. The only short pavement sections are at the beginning and end of the race.
