The NJ Halloween Half Marathon, 10K, and 5K

The NJ Halloween Half Marathon, 10K, and 5K is scheduled in Ridgefield Park, New Jersey, on October 31, 2026. The half marathon (13.1 miles) starts at 9:00 a.m., and the 10K and 5K follow together at 9:10 a.m., all on the road.

A 9:00 a.m. start is a gift for anyone who dislikes pre-dawn alarms, and it leaves room for a proper breakfast two to three hours out rather than a rushed one. Use that time: eat what you have eaten before your long runs, and keep the warm-up short if you are racing the half. Runners weighing up the options should let recent training decide — a weekly long run of nine miles or more points to the half, while anything less makes the 10K the smarter and more enjoyable choice.
