I started riding on Jan 1 2013. I started Strava'ing on Feb 18 2013. I've recorded every ride since, except for a couple of times when I was using a phone and it crapped out.

This means I have detailed info about how many miles I've ridden on each bike and every component on those bikes. I know how fast I was every time I rode a bike. I don't Strava for KOMs. I just use it to track my own performance and record my own history.

It's so easy to record. Why wouldn't I?
