Just back from doing the stamina podcast for the first time, not at all sure that's for me....I found it really challenging, far too fast for too long...had to walk quite a few times (yes Bazza, I guess I can go back to running after!) and my KM splits were all slower than usual...I wasn't feeling 100% when I went out, feared I might have a "Paula Radcliffe" moment.. I misjudged where it might take me to as well, and had a long walk home after, no energy to keep jogging even. Started to shiver too, that's never happened before....
I've discovered from swimming that when I up my stroke rate, my distance per stroke is seriously reduced, seems like a waste of energy...perhaps it will be the same for running, although I will try this podcast a couple more times before giving up on it.
