harrrdeharrr & nerrr nerrr . my work is 3.2km away & takes a max of 7 mins (unless there's a train...) and it's two lanes & uphill most of the way (ie perfect wheelie practice).
I'm sure someone will beat that, but I'm in the lead at the mo'!!!
My commute takes me accross a busy landing.
Traffic can be havoc if the kids are still doing laps. The cat can also ruin a trip too, get stuck behind her on the way to the office and I can lose about 4 seconds.
