This has been on my mind all week. What is "The Golden Distance" for a commute? Would it be time or distance? Should it have a more direct alternative for days of bad weather or when you're running late? I used to think 13 miles round trip was pretty good but now I find myself regularly extending it because I'm not going far enough, trying to make it more like 13 miles each way and because of the routes I take I miss out loads of lights so it's double the ride but less than double the time. I'm still pants at getting up early enough to lengthen my morning ride enough though, despite all my good intentions.
