How to pick a trail in Sunol
- Match the surface to your legs. 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.
- Loop or out-and-back? 1 trail here is a loop, so you finish back at the car with no backtracking — the easiest way to run a set distance without thinking about it. On an out-and-back you turn round at half your target distance, which makes any trail fit any run.
- 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. 1 is lit, which is what you want for winter evenings.
- Long run? Check water and restrooms first. 1 has trailhead parking, 1 has restrooms, and 1 has a water fountain in Sunol. Anything over an hour and those stop being nice-to-haves — and in summer, shade counts double.
- The small things that decide it. 1 shaded, 1 with mile markers, 1 that runners describe as quiet, 1 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.
