Is there something like a time limit to be considered a run as a speedrun? Or I can submit a 10 hours run and it will appear in the leaderboard?

as far as I know there's no time limit, moderators might have a lot a work thought :p

There's no time cap, but please don't shitpost by standing still in King's Pass for 10 hours or something like that

As long as the run is single segment (is filmed in a single session) and follows the submission rules then you can submit it regardless of the time, assuming the run is in good spirit and you did it with the intention to speedrun.

Very long runs will probably not get verified if it is clear you are making them long to waste the moderators' time however-

Basically, as long as you're not trolling, longer or slower runs will be completely fine! They might take a little bit longer to be verified if they are long however

Thanks y'all for solving my question, it helps a lot 👍 🙏
