Minute per kilometre is a unit of speed or velocity primarily used in endurance sports, particularly in running and cycling, to measure the rate of performance. It represents the number of minutes it takes to cover one kilometre distance. The symbol for minute per kilometre is min/km. This unit provides a straightforward and easily interpretable measure of pace for athletes and coaches to assess performance and plan training. By expressing speed in minutes per kilometre rather than kilometres per hour, individuals can directly relate their pace to the demands of a race or event. Minute per kilometre is especially valuable in practical contexts where athletes need to gauge their effort and adjust their strategy. In scientific and training environments, understanding pace in min/km helps in the precise analysis of physical exertion and the development of tailored fitness programmes.
