Reddit is crying foul, making a plausible argument that the encounter took place in a computer, not in the wilds of Canada. But the fact that this charging grizzly exists in CGI rather than along a biking path is, from a survival standpoint, a blessing. Bears can run "faster than the fastest human," says Lana M. Ciarniello, a grizzly bear expert and member of The International Union for the Conservation of Nature's Bear Specialist Group. At full tilt, grizzlies can hit 40 miles per hour, handily defeating the fleetest of Olympians.
Considering a grizzly's speed, the biker's choice to flee - instead of standing his ground - seems like tomfoolery. "Do not run. Do not turn your back," Ciarniello tells The Dodo. Either of these actions are apt to trigger a predatory response. Were she to encounter a bear while riding along a wooded path, Ciarniello says she would dismount, putting the bike between her and the bear. Without making eye contact - but trying to make herself seem bigger than she is - she would slowly edge away, talking to the bear to identify herself as human, not prey.
