How to pick a trail in Arnold
- Match the surface to your legs. Most of what's here is paved (2 of 2). 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. 1 trail in Arnold is open 24 hours — the rest can sit inside a park that gates at dusk and doesn't unlock until well after sunrise. 1 of the 2 listing carries posted opening hours — worth a look before you set an alarm.
- Long run? Check water and restrooms first. 2 have trailhead parking in Arnold. Anything over an hour and those stop being nice-to-haves — and in summer, shade counts double.
- The small things that decide it. 2 smooth and wide enough for a stroller or a wheelchair. Busy or quiet isn't a good-or-bad thing here: a busy path is the safer choice for a solo run at dawn, a quiet one is better for intervals.
