I dunno, on the one hand, there's been obvious improvement in technique, especially now that I'm running a bit faster. My landing is getting pretty consistent and the gait feels smooth. Several people have said I look good, although none of them approach your coaching competence. On the other hand, most BFRers report a period of transition lasting anywhere between 2 months and 2 years. When you consider I hadn't run for seven years when I started to get back in shape in 2010, was moderately overweight at the time, and have only been running consistently for a little over a year, I think experiencing a stress reaction in my mets last year was perfectly normal and even to be expected. I haven't had serious TOFP for many months now (knock on wood), and when I get a little achy these days an extra rest day or two seems to do the trick. By this time next year, I expect to have achieved my base fitness goals, perhaps even by the end of this year. If I haven't, I will reassess my approach. If I have, I will begin working on bonus points.
