Just curious. In this age of Strava and RideWithGPS, many of us upload rides to apps, but I still keep a detailed spreadsheet with entries for every ride- distance, average speed, which bike I rode, who I rode with, the weather, how I felt during the ride, whether my hip hurt or not, HR info, bike maintenance notes, etc etc. Sometimes my notes from a particular ride are a page long. Sometimes they are just a couple of sentences. Seldom are they less than that.

My guess is that many dedicated riders also keep notes. I'm just wondering how all of you do it (paper, spreadsheet, web tool...) how much detail you include, and how important it is to your riding regimen....
