Dan McQuade investigates his favorite training montage from the Rocky films – the run through Philadelphia in the second movie:

What’s always amused me about this scene is how absolutely little sense Rocky’s route makes: South Philly becomes North Philly becomes the Italian Market becomes North Philly again, and so on. Obviously, the montage isn’t mean to be taken seriously as an actual workout; it’s just a few scenes strung together so “Gonna Fly Now” can play and Rocky can finish at the top of the Art Museum steps.

But, I wondered, what if this roadwork were treated as one actual run? How far would Rocky go? Well, I decided to find out.

After breaking down the scene neighborhood by neighborhood, he calculates an answer:

Over thirty and a half miles. Rocky almost did a 50K. No wonder he won the rematch against Apollo!
