My interest in seeing my mileage (and speed) numbers, never particularly acute, dwindled to nothing when I broke my last bike computer, about 25 years ago. At that, I'd only ever glanced at the numbers and never logged them. Anyway, since I mostly randomly choose between a road bike, a TT bike, a track bike, and an old hybrid for my road rides, and since some of those rides are much hillier than others, sheer mileage numbers would be unrevealing.

I do like to know how many hours I ride each day---since retiring at age 69 last December, I've averaged around 12 to 14 hours of training-effort miles per week, with a string of several weeks of over 20 hours in the summer---but, again, I don't record those numbers.
