The Yonkers Marathon, held in Yonkers, New York, is the second oldest marathon in the United States, after the Boston Marathon. The course of the Yonkers Marathon has been known as being tough and hilly; New York City Marathon founder Fred Lebow cited it as one of his favorite marathons.
The Yonkers marathon (the standard distance, 42.195 km) is held on the third Sunday in October. In addition to the marathon, there is a half marathon race and a 5K course. At the end of the race there is a gathering and festivities centered on Van de Donck Park. In 1909 it was sponsored by the Mercury Athletic Club.
For its 90th anniversary in 2015 the track has a newly designed course that has added greater variety by eliminating the double-loop, and replacing it with a single-loop that follows a scenic route along the Hudson River, and then goes all over the city, past parks, past the Dunwoodie Golf Course (that offers a glimpse of the distant New York City skyline), and through a variety of neighborhoods.
The courses will be USATF certified and the marathon will be a Boston Marathon qualifier. Every year approximately 200 runners participate in the Yonkers marathon.
- Some references incorrectly state that Robert Fowler broke Johnny Hayes' world best in the marathon at the 1909 Yonkers Marathon. Fowler's mark was actually set at the Empire City Marathon on January 1, 1909.
