I used to run a few miles a day, almost every day for about a year. During that time I had runners high exactly 1 time. It was truly amazing - I felt like I could run forever. Had no muscle pain, no shortness of breath, it was like running on air. I only stopped because I was at the end of the run, and normally I would have collapsed, but I could have kept going that day no problem. I have never been able to repeat it. I wonder if I would have eventually died like a horse if I kept going? ;)
