This year I'm tracking how often I commute by driving versus cycling. After an exciting competitive start it's become a bit one-sided thanks to some adequate weather.
In the cold winter months I typically choose the shortest, hilliest route. It's 4.6 miles and takes me 16-19 minutes. In the summer, when it's daylight, dry and I'm fitter, I can do it in under 14 minutes.
Whilst it can be pretty cold on some days it's still far more enjoyable than driving.
In case you hadn't guessed 2,3,4,5 refers to the number of days cycled each week for the first 4 weeks this year.
