Training Mistakes for Distance Runners


For most runners who participate in marathons (26.2 miles) or half-marathons (13.1 miles), ample time is spent prior to the race engaged in a training regimen to help prepare for the longer distances. In the course of training, or on the day of the race, however, many will commit one of these four common mistakes, which can go on to be detrimental to their performance.


Weekly long runs are considered one of the most important components of training due to the physiological and psychological adaptations they create in the body, which are essential to completing long distances. Experts recommends a minimum distance of 8-10 miles for half marathoners and 15 miles for marathon runners completed at least twice before the race, but ideally further in advance. The following are some of the main adaptations weekly long runs are responsible for:

» Increased storage of glycogen, the primary storage form of carbohydrates in the body; training can raise glycogen stores and allow runners to retain enough fuel to finish the race without “hitting the wall”

» Improved psychological ability to handle long distances

» Improved ability to tolerate “pounding” legs will take while racing


The majority of marathons take place in the spring or fall due to the preferable weather conditions, and most recommended training programs last for at least 10-16 weeks. What some runners fail to take into account is the fact that the bulk of training for spring marathons will take place in the winter-with much colder temperatures, decreased motivation-and for fall marathons it’ll take place in summer-usually with hot/humid conditions and more social obligations than winter months. What’s suggested is to simply factor in all aspects of training and the time of year one attempts to complete it before beginning a program.


Trivial details that might go overlooked can cause major setbacks at race time, but if addressed properly, disaster can easily be averted. These are some typical examples:

» Not being used to racing in the morning, when most races begin

» Taking care of transportation logistics (i.e. planning enough time for parking)

» Eating and drinking properly before the race

» Clothing choices, including shoe, sock and outer garment wear

Most of these issues can be test-driven during weekly long runs prior to the race, so that when race day comes, all minor factors have already been experimented with and perfected.


When running such great distances, it’s easy to go out at an unsustainable pace and wind up not being able to finish the race. Runners should be well aware of what pace they’re capable of, and should bear in mind modifications that must be made on race day such as weather conditions. With that pace in mind, take a conservative approach and shoot for negative splits, which has a greater likelihood of guaranteeing a finish and minimal late-race discomfort.
