I enter the following into each of 12 monthly worksheets, with new spreadsheets each year: moving time, distance, altitude gain, bike (one of two), ride type (primarily audax, commute or other), ride (brief description of route). And one worksheet where I just enter miles by the week. From all of that I have other spreadsheets which show a variety of useless information such as monthly/weekly/annual stats according to ride type, bike type etc. So I can see that 2% of rides in 2012 were Audax, but that they accounted for 16% of annual distance and 12% of climbing. Or I could compare my average speed on the Thorn with that on the Sabbath, over the year, for a given month or ride type. Or which my best week was in terms of distance. Or what my average daily commute distance is by month. Or my longest ride on a Thursday. Or current Furlongs per Fortnight. I did flirt with cadence and heart rate for while, but they were a step too far for me. I could show you a variety of graphs as well.
I know I have a problem, but as vices go it’s a harmless one and takes very little time. What I am particularly inept at is recording useful information such as tyre and other component use. On the plus side, I’m the go-to guy for Excel queries at work.
