Lately I have not been happy with my running performance and I am not sure if it is mental or physical. Last night I decided to try and run my scheduled 2 miles as fast as I could - push myself to the limit. I finished my 2 miles in 17.47!!! It was hard and my body was at its max at the end - chest burning, legs on the verge of cramping, but I did it. Now I know if I just push myself I can get back to where I was before.
