About these units
Yard/Hour (yd/h)
A yard per hour is extremely slow and used only in rare cases where long-term monitoring of tiny movements is necessary—such as soil settlement in construction sites, creeping machinery, or long-term structural drift. Because the yard is an everyday imperial unit, yd/h sometimes appears in engineering logs or legacy datasets, though it is largely replaced by ft/h or mm/h in modern practice. Its use reflects the persistence of imperial measurements in certain specialized contexts.
Running Speed (run)
Human running speeds range widely: Average jogging (2.5–3.3 m/s or 9–12 km/h), Sprint speeds (8–12 m/s or 29–43 km/h). Elite sprinters can exceed 12 m/s, with Usain Bolt's peak reaching approximately 12.4 m/s. Running is biomechanically complex, involving elastic energy return, stride mechanics, ground-reaction forces, and cardiovascular performance. Sports science uses running speed to evaluate training outcomes, optimize gait, prevent injuries, and enhance athletic performance. Running speed provides a window into human physical capability and evolutionary adaptations.
