But it will all work out.
I discovered a major flaw in my goal of riding my bike more than I commute in 2012, and that is that my bike computer stops the timer when I am stopped on my bike. When I am out on my one hour bike ride at work, the timer usually reports back 42 to 51 minutes of riding, because there are a few long stoplights I must wait for.
My commutes home count the entire trip, including traffic and stoplights.
Simple solution, though, is to look at the clock at the beginning and ends of my rides and keep track of time that way, so there's more of a direct apple to apple comparison.
This will make my biking time seem longer in the data collected. But I still anticipate it will be a close race throughout the year.
