The 50k and 25k event will feature loops of a multi-surface single track trail that snakes through coastal maritime forest, opening out into views of tidal creek marsh wetlands. The course will be very flat, but we recommend choosing shoes appropriate for a varied trail surface. The scenic 3.88 mile course consists of eight laps for the 50k and four laps for the 25k event.
