I know a few of you have tried this, and while I have noted some benefits, I am finding certain negative consequences as well now....my sprint pace has gone from around 6:30 per KM, to over 8 mins, and at that I can't even get my HR up into Z4, and my easy running has gone from something starting with a 7 to way over 9 mins...
I've been on it for five months now...very tempted to give it up and just go back to doing my own thing...
Any explanations for why it should be going like this? Is it normal to go through a patch like this? Any encouragement you can give me at all? Yes I've checked the zones several times...
