===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.
