The researchers found that throughout the course of the races, the runners’ heart rate increased in a very controlled way, which appeared to be scaled to the distance of the race. When the heart rate response was scaled to the proportional distance completed, the results across races of different lengths were virtually identical. These findings support the notion that athletes actively manage the increasing strain on their body, in anticipation of reaching the finish line, constantly reassessing their levels of fatigue.

So they train their main muscle- heart- and all other peripheral muscles to climb slowly and then keep on truckin’ towards the finish line without hitting-the-wall.
