This is a short video from the helmet-cam of Dusan Vinžík while mountain biking with a buddy near Malinô Brdo in Slovakia. A bear comes out of nowhere and starts chasing his pal, presumably for eatings its porridge and breaking its furniture. Thankfully, it appears Dusan's screaming scared the bear off. Or maybe the bear just got tired. I'd get tired if I ran that far. "It was like forty feet." I'm breathing heavy just thinking about it. Also, now is probably a good time to pick up a great deal on a used mountain bike off Craigslist in Slovakia.
Keep going for the video.
Thanks to Tenpin, who wishes the bear had been wearing a GoPro so we could see things from its perspective.
