3.25 miles outside today (with the Superfeet, now that I"m breaking them in). Was dark when I started, but was bright by the time I finished. Didn't feel like I needed a headlight at any point, and the few cars that did go by gave me wide berth as I was plainly visible in my road construction workers day-glow reflective vest. Our neighborhood doesn't have sidewalks so I'm on the street.
