From the Organizer
Now in its 45th year, the 5k and Fun Run events will be held on its traditional Sunday of Labor Day weekend. Both events will be held on Sunday, September 6, 2026. The Closter 5k is the longest running, continuous 5k in the Northern Valley. We've got the prettiest course around!
Please note that this year's town celebration ("NOT" Labor Day celebration) is scheduled for 6 September. See the Closter Recreation Commission site for more info. This year's town celebration will not coincide with the 5K and Fun Run.
