I was telling coach
about this a couple of weeks ago, when we were interrupted by a medical emergency.
The May issue of O/NA had an article "Sore No More" by Owen Anderson which turned around my training problems. Beginning around November I had some hamstring soreness following a couple of races. I applied the usual approach of running more gently and taking a rest day when the muscles were particularly sore. This helped sporadically, but in the long haul I was getting fewer miles each month. Any attempt to get back to "normal" mileage was met with too much soreness.
I wondered if this was just my age (58) getting to me, and considered seeing a doctor, when the magazine arrived in the mail, and the article caught my attention. It talks about surprising benefits from special training that involves eccentric contractions, preventing soreness. I didn't grasp the technical physiology well, but I needed to try something.
So I started at-home strength training of the hamstrings once per day, in addition to my usual running. A couple of good runs following the initial strength training were encouraging, so I've kept it up. The result over the course of a month has been that I can run about as much as I wish (i.e. the knees being a limiting factor) and any remaining hamstring soreness isn't enough to be worrisome.
