I was so disappointed when I didn't manage run 3 after runs 1 and 2 had gone so well. I kept getting really bad stitch that covered all my tummy. I only managed 11 minutes on the first attempt. I kept redoing runs 1 and 2 and trying again. By the third attempt I was resigned to small increases in time each week but determined to do it even if it took me until Christmas next year as I was enjoying runs 1 and 2. Today, I ran 22 minutes.... Yippee, week 6 here I come. All I can say is, persevere!
