I just finished week 4 and can't believe I did it! I tried to go slow...remembering I am not winning a race, just trying to get through each session at this point. I STILL find the 3 minutes grueling, so I can't really believe I made it through the 5 minute sessions! I found this week, day 1 was just as difficult as day 3, other-than by day 3 I did pickup pace and distance. It is pretty amazing to go back and look at my earlier weeks/tracking pace and distance and see how I am improving, even when my mind is telling me I can't do this. Each week is a challenge, but I am keeping the faith of what others say here on the board: we can do it and it will get better. My cement legs and 49 year old body/mind needs all the support, encouragement/advice she can get right now to approach week 5.
