Williamsport, United States of America · Saturday 12 September 2026
The Lock 2 Lock Marathon takes place in September 2026 in Williamsport, Pennsylvania, offering runners a flat to gently rolling road course with minimal elevation change, making it an excellent choice if you're chasing a fast time or building confidence in your marathon fitness. The completely flat terrain means you can focus on your pacing and effort without worrying about significant climbs, though the gentle rolling sections will still demand respect from your legs in the final miles. This is a straightforward, no-surprise kind of race where conditions and effort are what will determine your outcome, not fighting the course itself. For runners training in hilly regions, this flat profile is a genuine advantage, and for those hunting a personal record, the predictable terrain removes one variable from the equation. Check the race website for specific details on aid station spacing and course support, as these matter more on a flat marathon where you'll be running at a steady effort for two hours or more.
