I live around Banqiao, and much prefer cycling over running so until about a month ago I wasn’t even aware how many areas really are bike lanes. There’s a path in the biggest park here with a huge bicycle lane marking on it, and a pedestrian lane next to it. The aforementioned pedestrian lane also has benches, a fountain, a couple bathrooms along it, and a couple other amenities. If you already guessed that pedestrians completely clog up the bicycle lane, rendering it inaccessible, you would be correct.
I get it though. I’ve walked in them before, only when there’s no bikes around though. And even then I look out for them and give them space. I agree with “clueless” because it seems most people here couldn’t give two shits about cyclists and nobody bothers looking behind them.
Edit-- I wrote this when I was pretty sleepy. I’d like to clarify, I mentioned running because it’s far more on foot which one is for pedestrians and which one is for bicycles.
