Why So Many Marathons are Lost – not Won

In order to separate and clarify the elements of breakthrough marathon performance we need to acknowledge some of the most widespread problems. Too much dependency on 'quantitative' long runs and generic tempo runs, for example, rather than 'qualitative' hill workouts, 5K & 10K paced sessions & speed-strength circuits designed to complement those essential longer efforts. By supervising these higher intensity exertions carefully, I see them have a much broader impact on V02 max and lactate threshold, key physiological variables that effect endurance running success.

The report looked at more than 34 million U.S. road race results between 1996 and 2016, the largest analysis of its kind. The only ones not getting slower are the top elite runners.

The Biopsychology of Heating and Cooling

Scientists have a pretty clear picture of what happens when summer sunlight, high air temperatures and/or humidity increase both skin and core temperatures in runners who increase their mileage training for a fall marathon or cyclists and triathletes preparing for autumn events. They bake. Muscles in motion generate enormous amounts of energy, only about 25 percent of which is used in contractions. The other 75 percent or so becomes body heat. Yet why someone has more difficulty dissipating body heat on one hot afternoon’s run than on another is still mysterious.

Hope Is Not A Strategy

It’s not uncommon to see the North African leaders in a race cast caution to the wind by impulsively going out faster in their opening mile than anyone else would dare. Sometimes they even sacrifice their own race by going out hard, dropping their competitors only to tire in the late stages to allow one of their teammates to ultimately win. Look at their stride. They don’t think too much about planning or splits. They do things in more in a natural way. But at the same time, they can also get carried away.
