I want to make a run but I can't play at once. Is it OK to make parts/episodes? What are the rules of that? If it has to be in one piece? Would it be OK to open a steam on Twitch and pause the game for a while and continue?

As I see, this guy (https://www.speedrun.com/gtavc/run/m7gvnn5m) made a 25h run and video is 76 minutes. I believe it has other parts.
