A fight between a hiker and a biker sent a woman to the hospital last week, Marin County Parks officials said.
The 65- year-old woman was hiking in the Terra Linda Sleepy Hollow Open Space preserve when a man on a bike grazed her going the opposite direction, officials said. They exchanged some heated words, and she chased after him, leading to a physical confrontation, officials said.
The woman went to the hospital with bruises on her arms, legs, and head, investigators said.
Deputies are now looking for the cyclist.
