Running at full speed

Turns out full speed is running at an 1/8 of a mile per mile.  Went run/walking today with friends and went one mile at full speed and then one mile at half speed.  It was good no new developments.  My sisters plan on being at 3 miles by end of Sept and so do I ...we shall see!  I felt good today although once again it is hard to start and harder to keep going.  I am sure it wont get easier just more worth it.....Bye
