Here’s yet another video that should convince you to stay way away from bears. If these beasts are willing to chase after a band of wild horses, they definitely won’t be scared to chase after you.

The speed of that grizzly is insane. For a little bit of context, this video was posted to Facebook by Help Alberta Wildies Society, an organization committed to protecting wild horses in the Rocky Mountains in Alberta. A followup video gives us a little more information, including clips of the bear’s mate following a few minutes behind, and an alternative viewing angle. You can check that out below.
