The Greenlawn Fire Department, Engine Company, Halloween 5K

The Greenlawn Fire Department, Engine Company, Halloween 5K is held annually in Greenlawn, New York, in the town of Huntington, and the 2026 edition falls on October 24 with a 9 a.m. start. You can take on the 5K (3.1 miles) as a race or join the community walk, with the start and the finish both at the fire department headquarters.

A costume contest runs alongside the race, and awards go to the top runners as well as a special recognition for the best costumes. Starting and finishing at the same place makes for straightforward logistics: park once, warm up nearby, and you are never far from your bag. If you plan to run in costume, try it on a training run first, since anything that flaps or restricts your arms will cost you more over three miles than you expect.
