People road their bicycles for 10-miles and held brief moments of silence at locations across the city where cyclists have been killed.
One mother got on a bike for the first time since her son was killed.
"Drive like it's your son or daughter on the street," said Julie Mitchell, a mother. "I think if people drove that way there would be a lot less deaths."
Participants want drivers to share the road with cyclists and make sure everyone is safe.
