This vibrant community event offers a welcoming atmosphere for athletes of all levels, featuring both a competitive 5K and an inclusive One Mile Fun Run. It's a day where seasoned runners share the course with families and children, fostering a true spirit of inclusion and fun.

The race boasts a beautiful rolling course that winds through the picturesque streets of Demarest. While no extensive climbs are noted, the "rolling" terrain promises an engaging challenge for participants. Historically, race day conditions around this time of year offer ideal running weather, with typical highs around 75°F and lows around 55°F, and only a 16% chance of precipitation. The event begins and concludes at the County Road School, located at 130 County Road, Demarest, NJ. Participants can look forward to post-race refreshments and live music, adding to the festive atmosphere.

Beyond the race itself, the Demarest 5K is renowned for its unique community engagement, notably through the "Principal's Challenge" which encourages local schoolchildren (K-8) to build healthy habits in the lead-up to the event. This long-standing tradition is more than just a race; it's a celebration of health, athleticism, and shared experiences that brings the entire community together.
