My high school followed the Paavo training program. We had a lot of success at the high school level. The school is actually very well known to guys here who've been around for awhile. However, before my time, despite having some national caliber runners, VERY few of them went on to do anything, and many of them were so burned out psychologically that they never even gave college running a shot. The assistant coach become the head coach my freshman year, and he slowly moved away from Paavo, but I still trained under that program my first three years.
I remember being told specifically to run PPMs as hard as I could, so I basically had three all out efforts every week in xc, two of them being 4+ miles in length and on concrete. I started having a lot of injuries my junior year of high school, and I was basically an injured mess from my senior year on. I ran in college but was injured more than I was healthy, and even when I was healthy I was always nursing something. I now have a few chronic injuries and seem to get injured very easily if I change my running almost at all (say, do 4 miles when I've only been doing 2-3). I have to wonder if this is the result of Paavo. You think so?
