DOWNTOWN LOS ANGELES — L.A.'s fourth CicLAvia event shut down ten miles of city streets on Sunday and welcomed about 100,000 cyclists, pedestrians, skaters and dog-walkers.

Organizers say the event is intended to bring together diverse communities, provide a break in congested city traffic and create an opportunity for exercise.

Although the event is focused on cycling, there were plenty of kid-friendly games and activities along the way. The day included bike polo, life-size chess and even an announcement from Mayor Antonio Villaraigosa about a new bike-share program coming to Los Angeles that will bring 4,000 rentable bikes to kiosks set up from Downtown to the Westside.

The next CicLAvia is set for Sunday Oct. 14.
