I don't formally log my km (canadian here!), but I do look at the odo on my computer all the time. For me it is a form of cheap entertainment.

BTW I had to replace the stock chain after about 2000 km on the one bike, and my rear tire after 2000 k on the other (shredded by glass). I guess I am tough on my parts, but then again I ride rain or shine. My winter bike needs all sorts of new stuff as salt is definitely bad for components.
