Course

The Lost Brook Preserve is a hidden gem of lush hardwood forest, carefully protected and maintained by the Tenafly Nature Center. Here, you’ll experience the landscape just as nature intended—authentic, rugged, and breathtakingly beautiful.
Instead of wide, manicured trails, you’ll traverse winding paths that showcase the area's natural terrain. Expect scenic footbridges over sparkling streams, ancient boulders shaped by glaciers, and trails lined with roots and rocks that add to the adventure.
But don’t be fooled—this course is still fast and runnable! Whether you're taking on the 5K or 10K, you’ll find plenty of opportunities to push your pace and embrace the thrill of the trail.
