The whole episode lasted about 10 minutes, after which Kauffman said he ran off, terrified that other mountain lions may be lurking about.
He said he eventually linked up with another runner and some hikers who gave him water and drove him to a hospital.
Kauffman said while the adrenaline rush and survival instinct helped him overcome the encounter, the fact that he chose not to use his earphones to listen to music that day also played a part.
“For the most part, I don’t feel any residual trauma,” he told KUNC radio. “I tend to move forward, this is my personality.”
Authorities have praised his quick-thinking, saying he handled the situation just right.
