After a decade of building, Bullis track may have the sport’s next star

Joe Lee looks out over the track in this corner of the pristine 102-acre campus at Bullis, a private high school in Potomac, Md., and his mind races. It is a warm afternoon in early April, and Lee has a practice to run. The Bulldogs’ coach hates complacency.

Lee is always moving. In his 11th year at the school, the former youth pastor breaks his athletes into groups, some pulling 25-pound sleds, others hopping mini hurdles. Each drill is calibrated, each piece of instruction delivered with purpose.
