Ok... I did a three mile run the other day and was feeling pretty good and toward the end decided to sprint the last 10th fast and hard. Well, as I finished and slowed down to a walk I got runner's high. It was amazing. The endorphins and energy kicked in and it was really like being drunk! Has anyone else every experienced this? I had heard about but never experienced it for myself until this run. Wow!! Makes me want to run even more now....
