The 23rd annual Spring Backyard Burn (SBYB) 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.

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.
