About the Lock 2 Lock Marathon
Historic canal locks frame this smaller Williamsport race. The marathon is separately entered from the half and 10K, with a generous limit that serves both qualifier attempts and steadier finishes.
Course
The certified route follows the C&O Canal Towpath between lock areas with little elevation change. Packed trail surface, narrow passages and repetitive scenery make focus and footing part of the effort.
Race-day weather
September in western Maryland may start cool and become warm or humid. Rain can soften the towpath, while tree cover limits sun on some sections and traps moisture on others.
