Heading out near dark in Portland
From late fall through winter it is dark in Portland before 6 p.m., so after-work runs and walks happen in the dark for months. If you head out close to sunset, be seen and be findable: wear a light and something reflective on the parts of you that move, pick a route with streetlights and other people, and send someone a live location link with a return time before you go. Our guide to running in the dark after the clocks change covers the rest.
