18th Annual Spring Backyard Burn

The Spring Backyard Burn (SBYB) 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 and you can race in just one race or sign up for the entire series. 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 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 series.  Racers must complete in at least two races (same distance) to be eligible for series prizes.

Start times are staggered between 7:30am and 9:30am because of COVID.  Please see individual race pages for detailed COVID operations plan. Take advantage of 10% savings by signing up for the full series (3 races).
