Sunny day took me jog this morning

When I wake up at 6.30 this morning, I found that it was sunny and calm. I suddenly decided to go jogging. I went to the Kinuta Park. When I go to the park, go around a jogging course there and come back home, it is about 5 km and takes 30 to 45 minutes. When I arrived at the park, I felt good and refreshed. I though to jog more frequently. However, when I was working at office, I felt sleepy. I took coffee a log to avoid sleeping.
