Not so much.
My previous routine was 2 - 4 miles 3 times a week for a couple of months before I'd start hurting too much, rest up, season change, too hot/cold start over a few months later - repeat.
Running only became enjoyable, and year-round, when I went barefoot/minimalist a little over 3 years ago. The first few months there was a significant period of adaptation/development/learning/discomfort but my mileage gradually increased from 4.5 miles home 3 x a week to the current 12 mile round trip which happens most days of the week. I transitioned from TRS to a reduced shoe to VFF over the summer/fall of 2009 but didn't do my first barefoot run till April 2010.
My only injury during transition was when a tendon behind my left knee pinched a nerve, which caused me a good deal of discomfort for about 3 weeks, in the Fall of 2010. A physio, who saw me sitting out an event, solved the problem with a 2 minute manipulation.
