Looks like it was filmed, staged, any clues to its origin before I start translating are appreciated?

Waders, rainwear, deep mud, gameshow.

I searched for the R logo and found references to a Chinese game show called Keep Running:

I'm not sure if this is it, but they do seem to have a lot of mud games on their channel:

It looks like there was a South Korean show and then a Chinese show with the same name.

It looks like the clip is from the South Korean show. S5 EP6. Starting at 50:19
