1 The average walking speed for older pedestrians was 4.11 feet per second, compared with 4.95 for younger pedestrians. 2  Older females had the slowest walking speed at 3.89 feet per second.
The average running speed of a healthy adult human is probably somewhere in the range of 10-15 miles per hour. This would be a measure of the average peak speed of every healthy adult human on the planet, regardless of gender, age, or size. Usain Bolt has been clocked at over 28mph, and scientists say that it is theoretically possible for humans to reach footspeeds of over 40mph. Humans Could Run 40 mph, in Theory.
