I just finished a 5.024km running that lasted about 0hh:24mm:34ss !
If someone asks me what is your perfect weather to run ' Today' is the answer. It was bit chilly in the morning. Once I was outside with my layered gear and started running, I never felt that good. It could be due to the fact that my legs were well rested. May be the combination of both, I could run easily. The first KM was a jogging pace on the concrete surface. Once I hit the part track into the wild, the surface was amazingly satisfying to run. No wonder 
This new found route is nice and away from the core downtown. It felt good to breathe the fresh air. I was not too much worried about the pace but I could feel - without looking at the watch- that I was running freely and easily once I hit the park. The pace came out to be sub 5 min/km which is very good by my standard. The heart rate was usual and did not feel exhausted at any point. All an all, a very good morning 5K to begin the day with.
