Just something to digest on the many different running styles out there in the world.
No matter what form or running style you practice or perform; if you don't keep your feet moving back towards your body before contact with the ground, you won't have good results. Good results as far as performance increase or injury prevention and reductions.
The slower you run the smaller your steps should be. When running faster you have the option of small step or bigger steps. Small steps and big steps would be how high my knees lift up.
Small steps and big steps is not the same as stride length as stride lentgh is the amount of time you spend in the air between steps or the non-supported phase of running.
Stride frequency is the amount of time from your foot losing contact with the ground and coming back in contact with the ground. Some people limit stride fequecny to the amount of time it takes to reposition the leg.
Why do people have so many problems running? They don't do this one thing; keep their feet moving towards the body before their foot contacts with the ground.
You would essentialy bound from step to step. Which is the extra bouncing that people try to eliminate. This bounce or bound creates high landing impact on your hips and knee joints if the person lands heel or flat footed.
It also creates what use to be called shin splints if the person lands on their toes.
