Running on Empty

Yesterday I ran on the treadmill for the 2nd day in a row.

Usually I set the speed at 10.0 km/hr and run at comfortable pace. Yesterday I was curious on my fitnes level after fasting nearly one month , so I set a faster pace at 10.5 km/hr.

I was running OK for the first 3 km. The next 1 km was harder as the treadmill was automatically inclined up by 1 degree.

Then the last 1 km became much harder. I had to concentrate to keep going. The words "Focus, Focus..." ala what Mr Miyagi said to Daniel san in the Karate Kid movie appeared in my mind. I focused and kept going...I felt a little bit light headed.

At the end of 5 km, I felt empty inside, as though all energy have been drained out of my body. Fortunately after 5 minutes, I recovered.
