How many kilometres does a footballer run in a match?

How to get close to this number

Build this one from pace rather than from memory. A match runs an hour and a half, a footballer spends most of it walking or jogging rather than sprinting, and a steady jog covers a few kilometres in an hour. Multiply the two and you arrive within a kilometre or so of the answer. The decomposition works because it forces you to price in the walking, which is what dominates the total.

The usual error is to imagine the highlights. Television shows the sprints, the overlaps and the counter-attacks, so the mental image of a match is one of continuous running, and estimates come out far too high. In reality the ball is in play for only part of the ninety minutes, and a player at full speed for even a single kilometre across the whole game is working extremely hard — as the explanation above notes, sprinting is a small slice of the total.

The figure depends entirely on how it is tracked. Optical camera systems, GPS vests and older manual methods do not agree, and each generation of tracking has nudged the published averages. Position matters more than fitness, too: the spread between a central midfielder and a goalkeeper is larger than the spread between an average team and an elite one, so a single "footballer" average always hides a wide distribution.
