I completed week 1 this morning. I can't say that run 3 was any easier than run 1. The idea of being able to run for a sustained period just seems laughable at the moment - despite how many positive things I have read!
Also, I am really struggling to catch my breath after the first running section of each session, although it gets progressively easier as the session goes on, and the later running sections have been the easiest on each of this week's runs. Any tips for getting my breathing under control right from the start? I have the same problem when I do the first couple of lengths when swimming but then seem to settle into a rhythm, but it's far worse when running.
