===Upright posture and slight forward lean===
Leaning forward places a runner's center of mass on the front part of the foot, which avoids landing on the heel and facilitates the use of the spring mechanism of the foot. Additionally, it facilitates avoiding the braking effect that occurs when a runner lands their foot in front of the center of mass. Although maintaining an upright posture is crucial, runners should also keep their frame relaxed and engage their core to keep their posture stable. This helps prevent injury as long as the body is neither rigid nor tense. The most common running mistakes are tilting the chin up and scrunching shoulders.<ref name="Dr. Michael Yessis 2000">{{cite book |author= Michael Yessis |title= Explosive Running |publisher= McGraw-Hill Companies, Inc. |edition= 1st |year= 2000 |isbn= 978-0-8092-9899-0 |url-access= registration |url=https://archive.org/details/explosiverunning0000yess }}</ref>

===Stride rate and types===
Exercise physiologists have found that the stride rates are extremely consistent across professional runners, between 185 and 200 steps per minute. The main difference between long- and short-distance runners is the length of stride rather than the rate of stride.<ref>{{cite journal | last = Hoffman | first = K. | year = 1971 | title = Stature, leg length and stride frequency | journal=Track Technique | volume = 46 | pages = 1463–1469}}</ref><ref>{{cite journal | last = Rompottie | first= K. | year =1972 | title = A study of stride length in running | journal=International Track and Field | pages = 249–256}}</ref>

During running, the [[speed]] at which the runner moves may be calculated by multiplying the [[cadence (gait)|cadence]] (steps per minute) by the stride length. {{anchor|Pace}}Running is often measured in terms of '''pace''',<ref>{{cite web|url=http://revelsports.com/pace_Chart.htm|title=Revel Sports Pace Chart|work=revelsports.com|date=25 November 2021}}</ref> expressed in [[Unit of measurement|units]] of minutes per mile or minutes per kilometer (the [[Multiplicative inverse|inverse]] of speed, in mph or km/h).
Some coaches advocate training at a combination of specific paces related to one's fitness to stimulate various physiological improvements.<ref>{{cite web |url=http://pfitzinger.com/marathontraining.shtml |title=Pete Pfitzinger – Training Information for Runners – Optimal Marathon Training |publisher=Pfitzinger.com |accessdate=21 August 2012 |archive-date=7 February 2016 |archive-url=https://web.archive.org/web/20160207220219/http://pfitzinger.com/marathontraining.shtml |url-status=dead }}</ref>

Different types of stride are necessary for different types of running. When sprinting, runners stay on their toes bringing their legs up, using shorter and faster strides. Long-distance runners tend to have more relaxed strides that vary.
