An 83-year-old Renton woman died Monday after suffering head injuries in a collision with a bicyclist on Sunday afternoon.

Just after 4:45 p.m. Sunday, Renton police were called to a collision involving a bicyclist and pedestrian on the Cedar River Trail, approximately a quarter mile east of Highway 405, according to Renton police Cmdr. Paul Cline.

The woman was walking east on the trail and two cyclists, also eastbound, came up behind her and off to her left side, Cline said in a news release. As the cyclists began to pass the woman, she stepped in front of them and was struck, Cline said.

Both the woman and the 57-year-old bicyclist were knocked to the ground, he said. The cyclist was treated at the scene for minor injuries and the woman was rushed to Harborview Medical Center in Seattle with critical head injuries, Cline said.
