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.
In this long run, you start at your normal run pace but you try to average your goal marathon pace for the last 30 to 60 minutes of the run. In most programs, I simply alternate the two types of long runs-one weekend, long, steady distance and the next, a fast finish long run.ow to Implement. While I recommend a two-hour long, steady run virtually year round for most runners, you should not start the fast finish long runs until 8-10 weeks before the marathon. Too many of these workouts and you will peak too soon and be flat by marathon day.
