Completed week 3 but found it very hard, i'm unfit, overweight and 58 yrs old. I have never run before, not even as a child. Was terrified to run 3mins and found the second 3 mins very difficult although did manage to do it, Now am not sure whether to repeat week 3 and then feel move confident to move onto week 4 or give it a go. the thought of running for 5mins seems too much of a leap, its not my legs but my breathing that gets me. Also thinking of running in the morning before breakfast due to hot weather, will this be a problem?
