Running trails in Middlesex, NJ
Middlesex has 1 trail in the directory — 1 paved. Every one posts opening hours, so you can check the gate before an early start. They're ranked here by rating weighted by review volume, across 38 Google reviews. Each listing shows what runners actually decide on — surface, loop distance, shade, lighting, restrooms and trailhead parking — instead of a made-up difficulty score.
How to pick a trail in Middlesex
- Match the surface to your legs. Most of what's here is paved (1 of 1). Asphalt and concrete are fast, predictable and runnable year-round but the least forgiving; crushed limestone and dirt take the sting out of high mileage; boardwalk is flat and scenic but slick in the wet. If your shins or knees are complaining, the fix that actually works is varying the surface you run on rather than chasing one "best" one. More paved trails →
- Loop or out-and-back? A loop finishes back at the car with no backtracking; on an out-and-back you simply turn round at half your distance.
- Check the hours before a 6am run. Plenty of trails sit inside parks that gate at dusk and don't unlock until well after sunrise, so a trail that's perfect at lunchtime can be locked at 6am. 1 of the 1 listing carries posted opening hours — worth a look before you set an alarm.
