D&L Half Marathon Run and Walk - Route

D&L Half Marathon Course

Most of the course follows a rail-trail portion of the D&L Trail on former Lehigh Valley Railroad – stacks of railroad timbers can still be seen in some areas. Your journey will entail a peaceful route through lush autumn forests. The beginning of the course follows two-lane streets from Northern Lehigh High School to the Slate Heritage Trail. After a short distance on the Slate Heritage Trail, it connects to the D&L Trail at the Slatington Trailhead and follows the D&L Trail to the finish line in Northampton’s Canal Street Park. When the course crosses the Lehigh River on Route 329 in Northampton, the trail switches from rail-trail to canal towpath although this section of canal no longer exists through the park.
