The premier trail half marathon this side of the Mississippi!
Paine to Pain Trail Half-Marathon, hosted by NewRo Runners, is a giant single loop that winds its way through the woods and trails of five different parks in lower Westchester County. You never run the same trail twice and will spend 90% of your time on dirt (and rocks and roots) in the shade of the woods.
Many of the trails are completely hidden from public view and host a wide variety of wildlife including deer, fox, coyote, turtles, rabbits, hawks, owls, herons, wild turkeys, bald eagles (as of April 2021), and other critters.
See below for an elevation chart of the course.
