In addition to being a cyclist, I am also a runner. I have never experienced a jogging stroller in the bike lane but a solo runner hogging up the lane. The only problem that I have is they are running in the opposite direction closer to the line than curb. I can't see behind me so I need to stay within the bike lane so that I will not be hit by a car. I would much rather see one run with a stroller in the wide bike lane than on the sidewalk. Sidewalks are narrow and difficult to pass another in some areas. A runner will have more of a difficult time if he/she has to constantly pass three abreast female talking walkers and the ups and downs of sidewalk curbs. They are also harder on the knees than is asphalt. I don't do concrete for this reason.
