St. Luke's D&L RaceFest

St. Luke’s D&L RaceFest is a four-race event in the Lehigh Valley featuring a USATF-certified marathon, a marathon relay, and the D&L Heritage Half Marathon Run and Half Marathon Walk. Start lines are in downtown Allentown and Bethlehem, with a finish in downtown Easton.

Most courses traverse the scenic and historic D&L Trail along the Lehigh River, offering a gentle net downhill on gravel or paved sections. The festival emphasizes community, health, and outdoor recreation, plus post-race festivities and free race photos. Proceeds support the Delaware & Lehigh National Heritage Corridor’s programming and trail development. Visit the organization's website for the most recent information.
