Fall Backyard Burn Trail Running Series
5 Mile or 10 Mile
18th Annual Fall Backyard Burn
The Fall Backyard Burn (FBYB) 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, two, three, or all four 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).
