Joggers, walkers, jaywalkers, parked cars, delivery trucks, hoboes pushing carts are not going to get off the bike lane. Like it or not, legal or not they are a hazard we have to deal with. What irritates me just as much are the tricycle riding hot dog/fast food vendors taking the whole sidewalk.

BTW: Concrete vs. asphalt. IDK, but joggers believe it. Go to a running forum. Discuss it with them and see what you get.
