If Brad Paras was looking for an adrenaline rush, he certainly got one.

The mountain biker was trail riding with his cousin in Jasper National Park in the Canadian Rockies when he heard a growl. "[I] looked to my right to see a grizzly bear charging at me," Paras explains on his YouTube account. "After careening down the hill a bit on my bike, I was able to distance myself from the bear."
