Fran that is a fantastic dream. I have had a fitness related dream a year ago.

It was after my first run on the treadmill. (Much like the run you experienced today)
It was such a big deal for me not to just be able to run but also that I
wanted to run. I was so nervous as I inched up the speed on the treadmill afraid I was going to fly off. When I returned home DH asked how it went and I said, "I ran today." This was just huge. All afternoon I would get his attention and then say, "I ran today." Before going to bed that night I said it again.

(Yeah, I drove him crazy with this but he is a patient man...) No surprise, that evening my dream was about running.
There is a park with a pond in the middle that I used to go to when I was in college and I would walk or rollerblade around it. I was starting to gain serious weight at that point in my life and could not have entertained the idea of running. Well, in my dream I was running in that park and I felt like I was ten again. I felt such peace. I woke up with the understanding that this must become a permanent part of my life. I will run. Shortly after this I developed a stress fracture in the hip and spent the next ten months recovering.
My goal this summer is to run that park.
