Something over 3,700 km (or 2,300 miles) divided more or less evenly between the commuter (hybrid) and the weekender (road bike). That's the most I have ever done by such a long way I'm not even going to count it. And it's warm enough that I could even be riding in this week, except that I'm no longer in bike mode and am about to try spinning classes so I don't get too horribly unfit during the off season.
