How many minutes is the Super Mario Bros speedrun world record?

How to get close to this number

Count the levels rather than the minutes. A speedrun of this game skips most of it through warp zones, so the run is a handful of stages plus the final castle, and each stage is a sprint of well under a minute. Add them up and the total has to be small — a few minutes, not tens of them. Decomposing a route into its parts beats guessing the whole.

Most people anchor on how long the game took them, which is the wrong quantity entirely. As the explanation notes, finishing it took ordinary players weeks in 1985. A world-record run is not a fast version of that experience; it is a different activity, in which the route, every enemy position and every frame of input is known in advance and rehearsed thousands of times.

What makes this record unusual is that it is nearly finished. Improvements now arrive in hundredths of a second, extracted from frame-perfect inputs where a single frame early or late costs the attempt, and the community has calculated how close the current time sits to the theoretical minimum. Records that approach a hard physical or software limit stop behaving like records and start behaving like constants, which is what makes this a stable thing to ask about.
