How to pick a trail in Black Diamond
- Match the surface to your legs. Black Diamond gives you a choice: 2 natural surface and 1 mixed. 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 natural surface 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. Every trail in Black Diamond is listed as open 24 hours, so an early start is never the problem. 4 of the 4 listings carry posted opening hours — worth a look before you set an alarm.
- Long run? Check water and restrooms first. 2 have trailhead parking and 1 has restrooms in Black Diamond. Anything over an hour and those stop being nice-to-haves — and in summer, shade counts double.
- The small things that decide it. 1 with mile markers, 3 dog-friendly, and 1 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.
