Furthermore, if the median age of a marathon participant is about 40, then the average maximum heart rate of a U.S. marathoner is about 180. Seventy percent of 180 is 126, while 80 percent is 144. Therefore, the heart rate of a mid-pack runner during a marathon is near the middle of the range -- between 126 and 144, or 135 beats per minute.
