I have about thirty years-worth of handwritten workout logs. I still do it. Although, since I began using Strava a couple years ago I've gotten a little lazy about logging, and every couple of weeks I have to backfill and bring it up to date. But, I've always found that knowing my weekly, monthly, annual, and lifetime totals has served as a motivator. I.e. if I know that a certain milestone is only ## miles away...I'll lengthen my ride, or I'll add a ride(s) that I might not otherwise do.
