> when it comes to comparing running VS walking, 20-30 km feels like the distance you should use, as that's a distance most people could walk daily over an extended period of time (e.g a week).
20-30km every day for a week, i.e. 140-210 km/week?
Fun fact, according to [1] 160-220 km/week is the training regime of world champion marathon runners like Eliud Kipchoge.
That guy that ran across America did 72 miles (115 km) per day [2]
But these certainly aren't "most people" weekly running distances :)
