I run to my halfway/turning-back point and then allow myself twenty/thirty seconds walking where I take two deep breathsand then run back. I have done this 4 times. I know it takes me time to get my breathing sorted and the run back is comparatively easy. I thought that tomorrow I would try a circular route to see if this helped and see if I could move up to 28 minutes. Part of me thinks that this is now more psychological but am I cheating or should I accept that I am achieving success?
