Well I just made an update to my Bicycling spreadsheet. I had it for 2 bikes, and I dropped that to just one. I corrected the spelling, and made some tweaks so it would run a little better. I guess I should have tried it before I posted it, because I found some things that were just dumb.
I dropped the 2 bike format because I only ride one bike, and the 2 bike format was just ugly.
I posted the spreadsheet on my web page, and you can get to it from my cycling page.
If you check it out, let me know what you think. It seems to work for my riding.
