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.

    ENDURE – Last Man Standing is a Long Island endurance running event using a Last Man Standing format. Runners complete a fixed 4.2-mile loop every hour, on the hour. Finish the loop within the hour, and you earn the chance to start again. Miss the cutoff or decide you’re done, and your race ends. The event continues until one runner remains or the event time window concludes. To amp things up, every few hours we will lower the time cut-off.

    The course will use designated park trails and/or park roads with a centralized start and finish area and aid station. Exact venue and course details will be shared once park permits are finalized.
