Understanding Running Pace
The concept of pace calculation was popularized by renowned running coach Jack Daniels in the 1970s through his book “Daniels’ Running Formula”. Before this scientific approach, runners relied primarily on subjective feel and experience.
Today, pace calculation is endorsed by major organizations like World Athletics and Runner’s World. The fundamental formula is simple:
Pace Calculation Formula
Pace = Time / Distance
Where pace is measured in minutes per kilometer or mile, time in minutes, and distance in kilometers or miles.
