     I felt like I accomplished a huge goal after finishing this run. Now the runs just start stacking up each week. No more little runs, most of the runs now will be 2 to 3 miles for the short days and then on Saturday's they just keep getting longer. Still don't know how I am going to be able to run that long, but I will worry about that week to week.
