Quick answer
A polar bear can reach about 40 km/h (25 mph) on land in short bursts, depending on terrain, motivation, and individual condition.
Key takeaway
A polar bear can reach about 40 km/h (25 mph) on land in short bursts, depending on terrain, motivation, and individual condition.
Top speed
Published figures put polar bear speed near 40 km/h (25 mph) on land. These are typically peak sprint estimates, not cruising speeds sustained for long distances.
Sprint versus endurance
Most species accelerate hard for capture or escape, then recover. Open terrain favours higher recorded speeds; dense cover favours agility over raw pace.
Anatomy that helps
Limb length, muscle fibre mix, and body mass (300–700 kg (660–1,540 lb)) shape acceleration and top end. Heavier animals may hit hard but tire sooner.
Compared with people
Healthy adult humans jog far slower than most cursorial mammals. Never try to outrun wildlife — create distance and barriers instead.
Field tip
Speed estimates vary by study method (radar, filming, anecdote). Treat ranges as approximate and prefer recent peer-reviewed or museum summaries when available.
Built for the Arctic
Polar bears are superbly adapted to extreme cold, with a thick layer of fat, dense insulating fur, and large paws that spread their weight on thin ice and act as paddles when swimming. Their fur appears white but is actually translucent, and their skin underneath is black.
Hunting on the ice
Polar bears mainly hunt ringed and bearded seals, waiting patiently beside breathing holes in the sea ice. The fat-rich seal blubber provides the energy they need to survive, which is why access to sea ice is essential to their survival.
Marine mammals
Although they live and travel on land and ice, polar bears are classified as marine mammals because they depend on the ocean for food. They are powerful long-distance swimmers, capable of crossing many kilometers of open water.
Conservation
Polar bears are Vulnerable and have become a global symbol of climate change. As the Arctic warms and sea ice forms later and melts earlier, bears have less time to hunt seals, leading to poorer body condition and lower cub survival.
Research notes
Figures for polar bears (Ursus maritimus) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter polar bears in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Vulnerable) when discussing conservation.
