The speed of an average human depends on the activity:

• Walking: about 3 miles per hour (5 km/h) on average, with typical ranges from roughly 2.5 to 4 mph depending on age, fitness, and terrain.

• Running: casual or everyday running speeds commonly fall around 5 to 6 mph (8–10 km/h) for many adults, though trained or recreational runners can run faster or slower depending on fitness and distance.

• Sprint speed (max effort): for the average person, sprinting speeds are well below elite levels; many recreational runners peak around 15–20 mph (24–32 km/h) in short bursts, with substantial individual variation due to training and genetics. Elite sprinters exceed this by a wide margin.

Notes and caveats:

• “Average” speeds vary by age, sex, fitness level, and environment (indoor treadmill vs. outdoor terrain), so there isn’t a single value that fits everyone. For walking, general population surveys commonly report around 3 mph as the central tendency, with some estimates near 2.5 mph for longer or more casual walks and up to 4 mph for fit individuals.

• If a specific comparison (e.g., age group, country, or fitness category) is of interest, I can pull targeted ranges and summarize them.

Direct answer:

• Average human walking speed: roughly 3 mph (about 5 km/h), with typical variation from about 2.5 to 4 mph.

• Average human running speed (non-elite, casual): roughly 5–6 mph (about 8–10 km/h).

• Maximum sprint speed for the average person is highly individual, but many non-elite adults sprint in the range of 15–20 mph (24–32 km/h) in short bursts; elite athletes run significantly faster.
