Running is both simple and complex, the process theoretically easy (left right left right repeat until end) the biomechanics rather harder due to the compromised nature of our existence.

Teaching or advising on form is therefore a potentially treacherous path, since each runner will be unique in their compromises and blocks.

When working, I tend to offer only 3 pointers- eyes forward, hips open and push away. I might, if the client is in a well supported posture and I experienced in body sensing, encourage them to open their chest, or loosen their ankles, but to focus on more can prove difficult, especially when tired.

These generate no confusing instructions, allow the runner to optimise their gait cycle naturally and help trigger appropriate neurological messages without overload.

All of which help reduce fatigue, injury and improve training effect.
