About Nassau Suffolk Trail Marathon & 15 Miler

Long Island has a rich and deep running culture. There are multiple events every weekend to choose from. However, runners that enjoy longer race distances or trail events have only a few options to choose from over the course of the entire year. This event will provide an opportunity for those that enjoy ultra or trail running to participate in a great event. A portion of the proceeds will benefit the Long Island Greenbelt Trail Conference, who help maintain the trails on Long Island.
