Defintion for Critical Speed
Long Definition
Critical Speed (CS) is the highest running speed a runner can maintain indefinitely without fatigue. It represents the threshold between sustainable and unsustainable effort. CS is determined through time trials or specific tests and is crucial for pacing strategies. For example, if a runner's CS is 5 m/s, they can sustain this pace for extended periods. Understanding CS helps runners optimize training, improve endurance, and set realistic race goals. It matters because training at or near CS can enhance aerobic capacity and delay fatigue, crucial for long-distance events.

Critical speed sits close to the effort you can sustain for roughly 30 to 40 minutes. Training around it, through tempo and threshold runs, helps you hold faster pace for longer.
