The runner was jogging alone on a trail in Horsetooth Mountain Park in Colorado and heard something following him on the trail. When he turned to look, a mountain lion pounced and bit him on the face and wrist.
The man choked the mountain lion to death with bare hands, according to Colorado Parks and Wildlife’s Northeast Region (CPW).
He then hiked to a local hospital to treat his injuries, and report the incident to the police.
The mountain lion was a juvenile and weighed at least 80 pounds.
The parks service said that there are less than 20 mountain lion-related fatalities in more than a century, noting that the big cats tend to avoid humans.
However, CPW said that if people were to meet with a mountain lion, they should not run. “Running may stimulate a lion’s instinct to chase and attack.”
If you have to fight, the parks service recommends targeting the animal’s eyes and nose.
