Bears can run surprisingly fast despite their large size. The top speeds for different bear species are approximately:

  • Grizzly bears can run up to about 35 to 40 miles per hour (56 to 64 km/h).
  • Black bears can run up to around 30 miles per hour (48 km/h).
  • Polar bears can run up to about 25 miles per hour (40 km/h).

Grizzly bears are the fastest runners among bears and can also sustain speeds of 25 to 28 mph for miles, showing significant endurance for a large animal. Black bears, though smaller, are still very fast sprinters at 30 mph. Polar bears, while the largest, are a bit slower on land and tend to overheat quickly if they sprint for long distances, so their top speed is lower at 25 mph.
