Today brings a close to National Bike Month. Here’s how I did:

  • 23 days with at least one ride, pretty good for an area with a reputation for rainy weather.
  • 415.5 miles on the bike in May. I’ve been riding recreationally since only last summer and my previous monthly high was 270 miles last July. (And this is not even close to being on the leaderboard for the Sacramento Region Bike Commute Month!)
  • 38 trips totalling 45 miles where I rode my bicycle instead of taking a car, reducing about 42 pounds1 (ROG, CO, Nox, CO2, PM10) or 168 pounds2 of air pollution.

How did you do?


1Estimate based on this quote that appeared on the Sacramento Region Bike Commute Month home page on May 31, 2007:

Bicycle commuters logged 321,542 miles and eliminated 302,631 pounds of air pollution (ROG, CO, Nox, CO2, PM10) from the Sacramento air basin this May, according to the Air Quality Management District!

Or roughly 0.94 pounds per mile.

2Estimate based on the Sacramento Region Bike Commute Month’s Fast Facts, which states:

A short four mile trip by bicycle keeps about 15 pounds of pollutants out of the air

Or about 3.75 pounds per mile.

I’ll have to do a little more digging to find out why the two methods differ so greatly.
