I ran 2.03 miles in 30 minutes. I made my goal of 2 miles but I actually expected to have a further distance. I'm not sure if I didn't set the treadmill high enough or if my pace was slower. It's so difficult to tell. I felt pretty good. When I started my shins were sore which is pretty normal for me. It takes a good 5-10 minutes for them to feel warmed up and to stop aching. My chest also felt tight as usual due to my asthma. I wonder if this feeling will go away the more I keep running?
