Sleepy Hollow Halloween 10K

Sleepy Hollow Halloween 10K is run in Sleepy Hollow, New York, on October 24, 2026. A kids fun run opens the morning at 9 a.m. and the 10K (6.2 miles) follows at 9:30 a.m.

A 10K is the distance where pacing starts to count. Six miles is too far to hold your 5K effort and too short to settle into marathon rhythm, so the useful target is an effort you could just about sustain for forty-five minutes to an hour. Build for eight weeks with one tempo run of twenty to twenty-five minutes at that effort, one longer easy run of an hour, and two or three relaxed runs. The half hour between the fun run and the main start also lets families get children finished before the adults line up.
