It's the 17th annual Bike to Work Day, this year again larger than last year.
The Bay Area Bicycle Coalition says that in 2007, some 43,000 Bay Area residents were using a bicycle as their primary means of getting to work every day. On Bike to Work Day, it's expected that more than 100,000 people will spin their pedals, many being first-time bike commuters.
In Alameda, last year's Bike to Work Day had more than 500 participants, according to 's Lucy Gigli. And this year, if the weather is nice again, she hopes for even more.
"This is an opportunity for people to get out and try riding to work and see how convenient it can be," Gigli said.
This year Alameda will host five Bike to Work Energizer stations, one at each of the ferry terminals, another at , near Pacific and Webster, on Park Street and one on the Harbor Bay side of the Bay Farm Bridge.
"We're celebrating the people who bike frequently and also trying to encourage new people to try it," said Gigli. "Sometimes people come and try for Bike to Work Day and then they continue."
According to the Silicon Valley Bicycle Coalition, nearly 40 percent of Bay Area commuters live within five miles of where they work. The Coalition believes that if all commuters living this close to their workplace left their cars at home on Bike to Work Day, in one day more than 60,000 vehicles would be off the road, reducing tailpipe emissions by more than 150,000 pounds.
Bikes, and biking, have come a long way. The Bay Area Bicycle Coalition has this really cool calculator for you to try. It estimates how much money you'll save by biking, how many calories you'll burn, and how many fewer pounds of carbon you'll be sending into the atmosphere.
If, for instance, home to work commute was a round trip of 10 miles, a commuter could save $6.66 by not driving, burn 530 calories, and keep 12.1 lbs of engine emissions out of the air.
Perhaps even cooler are very usable maps specific for Bay Area bicyclists created by 511.org. Using push pins on a sophisticated map to indicate your starting and ending locations, a route is planned out for you within moments.
