The Grizzly Bear's One Truly Unbeatable Move

A grizzly bear can hit 35 miles per hour. That's the top speed of a Clydesdale horse, a charging rhino, a sprinting Olympic athlete on their absolute best day—all of it, matched by a 400-pound animal built more like a tank than a sprinter. The catch is distance. A grizzly at full sprint exhausts itself within a few hundred yards. But that's not the point. The point is that there is no distance over which a human outpaces one. Not 100 yards. Not 50. You cannot out-run a grizzly. Ever. This matters because it's the one superlative where the grizzly's engineering doesn't trade off strength for speed or vice versa. A grizzly's front paws can pin a moose. Its bite force sits around 1,200 pounds per square inch—enough to snap a femur like a breadstick. Its sense of smell is roughly 2,000 times more acute than a human's; a grizzly can catch a scent from miles away, and follow it with a precision that reads like prophecy to anything unlucky enough to be the target. But those advantages don't matter if you see it coming from far away. The sprint, though—the raw velocity of a 400-pound animal accelerating across open ground—that's the one thing a grizzly doesn't need you to understand the danger of. You feel it. The speed isn't showy. A grizzly doesn't need to be the fastest animal in North America—that's the pronghorn, at 60 mph. It doesn't need to outpace a lion or a cheetah. It only needs to be faster than the thing in front of it. And at 35 mph, it always is.
