I understand why runners do this (asphalt is softer than concrete, no sidewalk in a given stretch) but as a cyclist I've had inattentive or aggressive(?) runners force me into traffic lanes by running contra-flow in a bike lane with painted directional arrows. Am not in your running shoes, so I won't judge where you need to run to feels safest, but please be on the lookout!

good point. I'm in the suburbs so no [explicitly] directional lanes but agreed runners should almost always yield nevertheless.
