Some runners insist that landing on your heel when you run is not only inefficient, but also places a terrible strain the knees.

To debunk the first point: a 2014 study published in Medicine And Science In Sports And Exercise found that runners who land on their rear foot are actually up to 9.1 per cent more economical than mid-foot strikers, and may be running up to one kilometre an hour faster.

And on the second point: a study by the University of Massachusetts found that while heel-strikers take on more force at the knee than mid- and forefoot strikers, they take on less force at the ankle.

Basically, you’re going to take a few knocks someplace, no matter how you run – so if landing on your heel works for you, you stick with it.
