So perhaps we should ban running. I have never taken a stroller to a race where they were specifically banned. Fortunately, there aren't many. The ones that do have good reasons, like the number of particiapants or crossing an expansion bridge. People here are just not so narrow minded.
Faster runners have the right of way.
When this first came up several years ago I was given the excuse about insurance costs. I guess the rest of your points are really weak. Thankfully I don't live where you do. And I guess you feel the same way. I feel we with the strollers are being looked at by other runners the way non-runners look at runners.
