I posted this in the comments but am also making a new topic post as well. Below are all the currently subbed episodes of Season 3, will keep updated if more subs come out. Hopefully this makes this season easier to watch. (named season 3 as the show officially changed names from 'Running Man China' to 'Keep Running' and also restarted the season counting)

Glad you appreciate it! I decided to put a masterlist together after struggling so much myself to find the available episodes and seeing that no one else had yet.
