It’s done. I ran my first half marathon. What a fun!. This is not a long sprint where you go near the boundaries of your body, as at 5 km, this is not a race that requires the extreme endurance as a marathon. It's just between the two: a respectable distance, which requires some strategy to preserve one’s reserves of glycogen and concentration, to have a little "juice" to make a final sprint (which is not as fast as 5 or 10 K) and cross the finish line.
