Cow charges cyclist on Boulder open space : County News : Boulder Daily Camera

BOULDER, Colo. — A cow charged a woman on the South Boulder Creek Trail on Monday afternoon, knocking her down, officials said.

The woman was riding her bike on the trail when she encountered the cow, and she stopped to let the animal pass, said Pete Taylor, a ranger for Boulder Open Space and Mountain Parks. The cow knocked the woman over and walked on her legs, he said.

He said the woman -- whose name wasn't released -- wasn’t seriously injured, and she refused medical treatment.

She didn’t appear to do anything to provoke the animal, which witnesses said appeared to have an injured leg, he said. The cow had left the scene by the time rangers arrived, but hikers coming down the trail were warning others about the rogue bovine.

Marshall Mesa open space is leased by livestock owners and used as grazing land. Taylor said the cow’s owner was notified.

In 2003, a woman was rammed three times and her pelvis fractured by a grazing mama cow when she accidentally ran between the animal and her calf on the South Boulder Creek Trail.

Jason Vogel, vice president of the Boulder Mountain Bike Alliance, called Monday's attack "odd, rare and random" and said he hasn’t heard of any other cows going after cyclists. It’s not even common to come across cows on the trails, he said, though they often can be seen nearby.

"It’s not something people should be concerned about," he said.
