This will be the 4th year for a new time, day and season for the Marathon. We added the marathon to accompany the half-marathon last year. 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. Source
