In 2014 I bike commuted more miles than ever before, because my office moved in mid 2013 to a farther location. My actual number of commuting days (either 145 or 146, depending on tomorrow) was about average.

As of today:

2046 miles bike commuting.

Car: 4 round trips (twice on days it had to go in for service or an emissions test, twice on days I got called back in the evening after biking to and fro earlier in the day.
Cab: 0.5 - I went home sick
Public transit: 61.5
Bike 145.

A bus token is $2.70 but I occasionally take the double-fare express bus, so my average daily bus fare was $5.66. That means that my 145 days of cycling would have cost around $821.20 using public transit. If I spend less than that on biking, I am coming out ahead.
