Just completed 'week 1, run 1' of C25K with no real problems. I'm sure my jogging/running technique is absolutely hopeless as I struggle to cushion my landing (it feels like I either land totally flat-footed or run slightly on the ball of my foot) but whenever I tried to consciously change it didn't really work. Other than that, no real issues - no cheating, no stopping, last 2 'run' sections were mildly uphill, no oxygen needed...(!)
Just done a few stretches but I need to watch some YouTube videos later to understand how to do them better.
Getting the first run out of the way is a massive relief as I really didn't know what to expect. Now I just need to learn how to land a bit lighter on my feet (hard when carrying 211 lb) as the 'thump' when I land is definitely amplified through my in-ear headphones (along with the heavy breathing!)
