It is interesting the kinds of challenges that people set for themselves. Via Pepe Jimenez, here is a video of someone in London getting off the underground train at one station, running to the next station, and getting on to the same train again. I am not sure what it proved, that he is a fast runner or that the trains are slow, but it is an impressive feat and fun to watch.
In the split screen, the left side shows the view from the camera on the runner’s head while the right side is taken by a friend who stays on the train.
I suspect there’s a rather limited subset of station pairs where this is feasible.

FWIW, I was a little child in Madrid, Spain back in the early 1960s, and lived in apartment 5A (fifth floor, first apartment) in a building with a creaky old elevator (remember the cages?). I liked to race up the stairs and beat the elevator — which I could not quite do if nobody on it got off in between.
(Ah, nostalgia!)
That was fun. Tom Scott had a video from a few years ago also doing some Tube racing, albeit with less athletic vigor. Apparently there are some instances where there is a considerably shorter path available if you ignore the maps & signs.
