I did it! I walked 5 miles on the Knobstone Trail this morning with Dad and Jim. We did it in less than 2 hrs. I did pretty good I think.....really never had to stop for very long and didn't suck wind too hard. It is nice to have something to gage my level of fitness by. I need to step things up to push myself to more labored breathing and faster heart rate during my workouts. I need a code "red" workout! Ha!
