The Peninsula Traffic Congestion Relief Alliance announced a 60% increase in bike commuters for Bike To Work Day this year over 2011.

The Alliance, which is the transportation demand management agency for San Mateo County on the San Francisco Peninsula in California, coordinated the 31 Bike To Work Day “Energizer Stations” in 17 cities throughout the county on May 10. Workers at each station tally the cyclists passing through their stations.
