> The average running speed of humans is around the same limit - 11 to 15 mph (17 to 25 kph). If you said, "the average running speed for trained male high school seniors is 10 mph", I might find that plausible. Probably high, but plausible. 1. Men are substantially faster than women. The number you gave is high for men, but ludicrous for women. 2. There is nothing average about a 15 mph (4 min mile) running speed. It is quite rare for men to achieve this speed and has literally never been accomplished by a women. 3. Those numbers reflect an unloaded run of exactly 1 mile. Commuting in the city by running would substantially slow people down.
