Critical Mass Bike Ride 2013: A Huge Success

After months of preparations, the event I volunteered at finally ended in success. :) Think it’s good to post the recap here.


Thanks to all sponsoring partners, volunteers and enthusiastic participants, the Critical Mass Bike Ride 2013 was a huge success!

Over 300 riders joined and had fun. We had a gorgeous girl riding to party in nightgown, aliens from space visiting us, a group of professional triathlon riders, a group of fun and creative gal-riders, also a grassy man dressed up as a moving eco-message. For more photos, please visit

Our volunteer core riding team designed the route to pass through the fabulous Longteng Avenue for the views on PuDong, then through the busy Xizhang South Road to gain attractions to our eco-message. For map, please check

Love the winners of that day. <3
