The Lost Brook Preserve is a dense stand of hardwood forest that is naturally maintained by the Tenafly Nature Center. This means that you will NOT find wide and nicely groomed trails here. Instead, you will discover the native terrain of this area. There will be sections of trail covered in rocks and roots, foot bridges over streams, and thousand year-old boulders moved by the glaciers that once covered this landscape. However, this is still an extremely runnable course and I will be expecting some fast times for both the 5 & 10 mile races. Be safe out there, but more importantly remember to have FUN!
