I do hope that things settle for you and hopefully they will as you've picked it up at niggle stage rather than more advanced. I also think that the physio was probably a good bet as they could perhaps diagnose more where it's coming from.
I changed to HR training and after a gap of 3 - 4 months (due to off-spring being at home and not being able to get out) returned to training, going from 0 - 45 m per week with no problem. I follow the J L Parker method, so when I started back in the summer, followed one of his programmes. I'm sensible (comes of my age
) but my weekly programme consists of one hard speed session (intervals) the others are all steadies or recovery runs. I did the January challenge last year and went from a weekly total of 25 - 30 ish m/wk to 50 m/wk in the second week,maintaining throughout the month, then continuing (childcare issues aside!) with that quite happily.
I'm sorry that you're not getting more assistance with the programme, I really hope that that will change and improve for you and that you'll get the level of advice that you were promised. Is it the same for the others? What about Steve, he seemed very helpful, is there any chance that he will be back to help? However, you have a wealth of experience yourself, lots of on-line support from forumites, so I'm confident that you can and will make it. And we'll all be there to celebrate with you
