Leg turnover naturally determines stride length
A small bit of history...
Legendary running coach Jack Daniels, born 1933 (named the worlds best running coach) began wondering about running cadence over 20 years ago, whether there was, in fact, an ideal cadence for optimal runner performance.
As a result, he decided, while watching the 1984 Olympics in Los Angeles with his wife (who acted as his assistant),to actually count the number of steps that Olympian runners from 800m to the Marathon typically took while competing. He (or rather they) discovered that there was a remarkable uniformity when it came to turnover among the worlds best runners.
All of them-- male or female, short or tall-- took between 180 and 200 steps per minute, with the higher numbers recorded at the lower end of the distance range. He wasn't able to say precisely why, but he had obviously discovered a manifestation of some very basic physiological (probably neurological) principle.
No runner, after all, is ever told, or ever consciously attempts, to take between 180 and 200 steps per minute; and yet here were the best distance runners in the world, all turning over more or less in sync. Armed with his data, Daniels then proceeded to count the steps of less accomplished runners (typically, those newest to the sport)and found that there cadences were typically much slower-- sometimes as slow as 160 steps per minute."
StrideUK believe that the combination of a light, wheeling turnover, with minimized bouncing, and greater quadriceps flexibility and knee flexion can help you achieve the right stride length and cadence for improved speeds at reduced injury risk, whether you're on an easy recovery run or in the midst of an intense track workout.
