Thursday, May 15th is Bike to Work Day. It will also be a Spare the Air Day, as the Bay Area Air Quality Management District predicts high levels of ozone in the air. Public transit in the Bay Area will not be free, as it has often been on past Spare the Air Days. Cyclists all over the Bay Area will choose two-wheeled transportation on this day. Several cities will have "Energizer" Stations with giveaways of items such as snacks and mussette and tote bags, while Bike Away from Work events will celebrate the day's achievements.

The San Francisco Bicycle Coalition reports that on May 8th of this year, bicyclists made up 48% of eastbound traffic in the City, which was a 30% increase over that time last year.
