It's not as far as you'd think.
Now you can do the Mario saves Princess Peach workout on a daily basis, thanks to Boston-based computer programmer Ian Albert and Mental Floss magazine. After a reader asked the magazine how many miles the Italian duo had to run, jump, and swim to get to the Princess, they were actually able to calculate it using some simple standard measurements.
There are some ground pounders out there who probably do harder workouts for fun.
Not to take anything away from your childhood or anything.
Mental Floss' Nick Green took the maps created through Ian Alberts screenshots of the game, calculated how large Mario and Luigi would be as normal human beings – that is, using their pre-mushroom growth hormone size – a human with their feet slightly more than shoulder width apart, an average of 26 inches.
Then, using no bonus areas or warp tunnels, Green calculated the distance from Mario's starting point to saving the princess, relative to that 26 inches between his feet. The final tally comes to 17,835 feet – 3.4 miles. Barely more than running a 5K fun run, though this number increases to 3.7 miles if you also calculate running all the bonus areas.
Super Mario PT will not be coming to your console anytime soon.
If we were going to make this a partial triathlon, then calculating the swimming distance would be 371 feet, roughly eight laps in an Olympic-sized pool, and another 344 feet with the bonus areas, so around 15 laps.
Keep in mind this is just running and swimming straight through, without calculating the physical toll of jumping, climbing stairs, crawling in tubes, and murdering birds and turtles or of running in a lava-filled enclosed castle. There's no doubt that rescuing the princess would be a little more difficult than we're making it out to be, but the Princess Rescue Workout would still be short work for many military members.
