The Experience

Now in its 49th year for the half-marathon course, the Tromptown Half Marathon is a true rural classic. The loop takes runners around a peaceful lake, then winds through the rolling countryside of three New York counties. Fresh country air, open valleys, and quiet roads define the experience—no crowds, just the sound of your own footsteps.

The course is USATF certified and pancake flat, with essentially no elevation gain, making it an ideal choice for a fast time or a first half. The new start and finish line keep logistics simple, and the loop format means you’re never far from the village of DeRuyter.

This is a low-key, hometown race with a loyal following. Runners rave about the scenic beauty and the pure, unpretentious atmosphere. Finish with a modest shirt and the satisfaction of a race that feels like a genuine community event.

Race-provided description

This will be the 6th year for a new time, day and season for the Marathon.  The two runs are some of New York State's, even nationally challenging, and yet scenic runs. The half-marathon takes you through parts of three counties, the marathon through four counties. That curious fact for the marathon should put us as number one in the nation in that category. The half-marathon course, of 49 years remains the same, but with new start and finish lines. It includes circling the lake, then the continuation of the sights, sounds, and smells of fresh country air intensity as you leave the dam, near the half-way point. As you head south for the finish line the views unfold of the valley's and the village to the east.  The marathon takes in the first 12.1 miles of the half-marathon before turning south, then east at about the 17 mile point. Beginning around the 20 mile marker one heads northwest and gradually ascends to Tromptown's own but short "heartbreak hill". From 22-25 miles one is heading west, finish line bound, descending with a wide panoramic view of three valleys and their surrounding hills. The last mile is level in the village. The marathon and half-marathon are loop courses. They start very near the finish line in front of the school. Both are newly certified. With the new marathon  and moving the start and finish lines for the half-marathon new certifications were required.     Half-Marathon:   The half-marathon is the same course as the last 49 years.  However, all runs start very near the school and all runs finish at the same place in front of the school.

Full Marathon:   This marathon is a Boston qualifier The first 12.1 miles of the marathon course uses the half marathon course. Both runs are loop courses. Course closes at 2:30 pm Liquid support every two miles or less.
