AnneV, I'm not just starting out, we've been working on increasing time, I started out with 1 minute walk/1 minute run. The total distance covered is this but I'm not running all of it, I walk in between. I think the advice is totally wrong to say run first one mile, it's a long way, start at 1 minute and you will need a walking break afterwards, I guarantee. In learning to change technique you need real slow aproach. I posted this thread after yesterday's run which finished in a strong heel pain. It was explained to me that this is where Achilles attaches to the heel bone. I had sore heel all day and had to walk slowly. This morning the pain was no longer there, I went for a run, 3 reps of 10 minutes with 2 minute walk in between and nothing hurts. It was really great. I just hope Thursday's run will be equally great and I will learn this soon.
