I started the plan 3 weeks ago after never being able to run for any length of time. In my previous post I asked why I found running so hard due to age and general health being on my side. Well, to cut a long story short after completing week 2 I decided to see how long I could run for and I managed a whole 15 mins! Since then I tried again but only managed 7 and it was much harder. Then yesterday I did 20 mins straight and found my breathing wasn't a struggle at all. The hardest part I find is overheating (I am using a treadmill in the gym and the fan is poor,) so, as stated above I am wondering if I really need to be following this at all? After completing 20 mins after just 3 weeks I am considering just practising. The sense of achievement I have from this is unbelievable, I feel like I have run a marathon!
