Course and logistics
The course is a 1.60-mile lollipop loop repeated twice to complete the 5K.

The loop is described as flat and not technical; road shoes are acceptable and winter traction recommendations may be provided before the event. The course will be marked with neon pink or reflective ribbon and red directional arrows.
Aid is provided on course with water, Skratch, and snacks; participants are asked to bring their own cup or bottle. The start/finish and check-in take place at the NYNJTC Headquarters; park in the Reservation parking lot and use the restrooms there. First aid supplies and an AED are available at the headquarters, and private changing tents are provided. Volunteer roles and hardship entry options are available. Refunds are not offered; deferral rules apply. Visit the organization's website for the most recent information.
