Okay, doc and Venus, I've been reading your replies and wondering when I would ever get to the point where I could run and not be anaerobic, and then, this morning, it happened! I did my usual 3 miles, and stayed under 160! Until the end, that is. I felt so good, I did another half mile. But most importantly, I ENJOYED it! And I could have talked, albeit breathlessly. Thanks for your suggestions and encouragement! It has helped me a lot!
