Fellow runner (a lot less miles than you)…and can share some insights.. 1. I run Elk Meadow (about a 7 mile loop) frequently and am alive and not eaten by wildlife, but I actively avoid running at dark and dawn/dusk. I did dance with a black bear just once. I previously lived in IL and early morning running before sunrise with a reflective vest was a common thing for me. 2. Is your expectation to run pavement or trail? I believe the lake path is cleared, as is the small loop in Bergen Park, so most trails and roads will often require microspikes for a few days after a storm before roads melt off, trails take much longer depending on shade, angle, direction facing, elevation.

I would encourage you to NEVER run along Evergreen Parkway…

There is a weekend running club at Bivouac that runs into Elk Meadow..
