No human has ever officially run 30 mph, but some have come close. The fastest recorded speed for a human is approximately 27.8 mph (44.72 km/h), achieved by Usain Bolt during his 100-meter world record sprint in 2009. This speed was measured at the peak of his run, around the 60–80 meter mark.
Reaching 30 mph would require exceptional physical capabilities and possibly advancements in biomechanics or technology. However, it remains beyond the limits of current human performance.
