Since I ride on our land--with curves, winding routes through brush, up and down sections, etc.--it's very difficult to know just how far I've gone (other than "as far as the first cedar from the corner post...as far as the second cedar from the corner post" etc.) I'd like to be able to track my distance in something other than country-speak. I looked up bike odometers online and found way more stuff than I can process. It seems like there are bike computers that will give you distance, all right, but include lots of other functions for which I have no use and do everything but push the pedals. Any recommendations?
