So, in fact, most commuters live more than 30 minutes from the station.

This is true. Many commuters take a bus to Chelmsford station from the outlying estates. Just too far to walk but bike is feasible.

But then, different thread, there is the lady trainee lawyer who runs the seven miles from Blackheath to the City each day to avoid the London
Bridge chaos:

And of course all the lady commuters will need to take two sets of shoes
if they walk(/run): the fashion shoes to match their outfit and the
comfortable ones. Not being sexist - it's just one of those well
understood differences.
