Well I finally mustered up the courage to go out in this heat and start week 4. It got to 7pm and after a good talking to, I went out. I came back sweltering but glad I went.
I was surprised to find that my chest didn't hurt - I've found before that my chest hurts and I can't breathe properly but I calmed down and counted my breathing and felt much better.
My legs however, were a different story! I really felt the burn in my calves and had to stop a couple of times during the brisk walk/rest periods, just to stretch them out slightly. However, it must be doing them some good, surely? I've obviously not used these muscles for a long time! I do do zumba once a week but I must be using a different muscle group to running.
Also, I remember other bloggers mentioning pumping arms as you run to get momentum up so i tried that and found it works!
Roll on run 2 tomorrow morning!
