Bicyclists take to streets in critical mass drawing attention to three fatalities in one week Riders stage 'die-in' at City & County Building Lance Hernandez, Denver7 and last updated 2021-05-24 01:35:31-04 DENVER -- It's been a brutal week for bicyclists on Metro Denver streets. Three bicyclists were struck and killed by drivers last week, and members of Denver's cycling community say that's three too many. They want changes to make streets safer. Dozens of bike riders took to the streets in a critical mass ride Sunday afternoon, to draw attention to the dangers of distracted driving, speed and impairment. "We're here today because we will not accept a world where three people are killed in one week, just because they're riding a bicycle," said critical mass organizer Allen Cowgill.
