WARNING: Graphic footage contained in the below video
Ultramarathon runner Dean Karnazes reveals he survived a coyote attack.
In a graphic video posted on Instagram late last week, the 59-year-old runner was seen with a bloody face and shirt while on the 150-mile run in California's Marin Headlands.
"I just had something rather terrifying happen," he said. Noticeably out of breath, he added, "I got attacked by a coyote. That was a first."
He said the coyote tackled him, but he scared it away after he "whacked it" with a pole he was carrying.
"Kind of brutal," Karnazes said. "Not sure what I'm gonna do. I guess I gotta keep going or else it'll probably come back for me."
Days later, he sent out a warning that asked people to stop feeding coyotes.
"As I've witnessed firsthand, people (mostly tourist) have been feeding wild coyotes in the Marin Headlands area of California. This has got to stop," he wrote alongside a photo that reads, "Do not feed the coyotes."
He urged anyone who witnessed coyotes being fed to "say something," adding: "The local Rangers are doing the best they can, but we trail runners are out in these areas more than anyone."
In the comments section, he joked, "I might have missed my stitches window, but my lips are now fuller and plumper. It's next level augmentation!"

Ahead of the attack, Karnazes shared footage of his view during his trek, showing off the gorgeous San Francisco night skyline that featured the city's Golden Gate Bridge.
"If you're wondering why anyone would do such a thing, maybe this view will give you part of the answer," he said with a laugh. "Look at that city."
