I say worries but actually I'm not worried as such. I have completed week 5 run one and it was tough but doable. I think my concerns are more in my head than physical now. I have spent years, no decades, telling myself I'm no good at sports that are aerobic in any nature and those doubts I am finding are creeping in when the runs are tough. I know I have a 20 minute run at the end of this week and I'm not panicking at all I just want to do it. How do you clear your mind and just run? It's when I have been running for a couple of minutes that it becomes negative. I want so badly to continue enjoying running, the weather is not helping either never the less I will be out at silly o'clock tomorrow morning with my high vis on!
