Don’t let your running and training be hampered by arbitrary tales that may lead you off track.  If you find yourself caught in the trap laid by one of these myths, it is time to set yourself free!

Myth #1:  If you don’t have time for the entire prescribed XXworkout, you should just skip the whole thing.

We all know the nagging pain of a day where the alarm didn’t go off, your toddler is sick, work is a fire drill, or the weather is garbage. The scheduled workout is Just. Not. Going. To. Happen.  In frustration, it can be tempting to bag everything and sulk.  Don’t.  Your schedule is the best-case scenario, and every single runner has had to punt and pivot now and again.  If the track workout isn’t an option, an aerobic run can still help clear your head, and keep you on track for either an adjusted workout day later in the week or next week’s tasks.  If the schedule calls for 45 minutes and you only have 25 minutes, your body will get a significant benefit from doing even half the work.  If you are taking an unplanned “zero” in the log, focus your mental energy on the positives – more freshness for the next session, accomplishment of the tasks and issues that have stolen your run time, and the confidence that a day or few off does not have to have a significant impact on your fitness level.

Myth #2:  Days off are for wimps.

Training hard is important to get toward your goal, but without recovery, your muscles don’t have the ability to adapt and recoup after the stress you have placed on them already.  Recuperation time allows your body to return to preparedness for the stimulus ahead and in doing so, get the most out of the upcoming challenge.  Running hard every day drives your body into a deeper and deeper hole from which it eventually becomes impossible to escape.   Build your schedule with some planned and regular rest, and the chances of you making it to the start line of your goal race will increase immensely.

Myth #3:  You will set a personal best every single race or you are not trying hard enough.

There are many, many factors that contribute to a personal best day.  An accurately (or inaccurately) measured course.  A tail or head wind.  Hills.  A bad meal the night before.  How well recovered you are.  Your bout of flu last week.  Neglecting to hydrate along the route or beforehand.  The list goes on and on.   These are not excuses, but factors which can both enhance or diminish the yield from your training up to that point.  Your actual fitness plays the largest role, but smart training includes a slight cyclical effect where recovery periods are interspersed with hard training and tapering for goal events.  100% effort each time can be a good way to practice the significant demand your body will require when it is primed for a signature day, but even top level effort each time may not always result in a new level of achievement, particularly for experienced runners who have been through the train and taper cycle in the past.  Concentrate on the quality of your preparation, the execution of your plan, and when your body is ready, you’ll have good racing habits and attitude down pat.

Myth #4a:  The more cushioning in your shoes, the better chance you have of avoiding injury.

Most athletes do not need to purchase the shoes with the maximum potential padding, structure, or stability in order to stay injury free, and in fact these shoes can sometimes impede your stride from operating at its greatest efficiency.  Each foot and every person is different.  Consider getting a gait analysis from an experienced staff member at a reputable running specialty store in your neck of the woods, and adding that info to your reasoning as you choose your next pair of shoes.  Well-cushioned shoes have indeed helped many non-runners become runners through the years, but for many athletes, other choices may serve the body better.

Myth #4b:  The less cushioning in your shoes, the better chance you have of avoiding injury.

In recent years, thousands of runners have become enamored with the “minimalist” segment of the running shoe market.  These are typically footwear with much or all of the heel lift eliminated, or shoes meant to simulate running barefoot with various ways of wrapping around the foot or articulating the sole.  While incorporating barefoot running or minimalist footwear into a larger program to strengthen the foot and lower leg can be very beneficial, these decisions must be made in context.  Injury history, the restraint to gradually incorporate this type of running, and the availability of suitable and safe terrain must all be considered.  Again, minimalist footwear have been invaluable tools for many runners, but just because you want to be one of those runners, doesn’t mean you are.  Get some input from your experienced local running specialty retailer or a podiatrist, and don’t do anything all at once.

Myth #5:  Training for a marathon is a great crash diet.

Physical fitness is a great by-product of decision to train for a half or full marathon.  Weight loss may result, but the “goal beyond the goal” should always be sustainable, healthy habits.  Athleticism, strength, endurance are all aspects of your best self that need to come to the fore in order for you to reach your race finish line.  Explicit, short term dieting and caloric reduction while maintaining a schedule of challenging running tasks can be detrimental to your training and health at best, and dangerous at worst.  We want running to be a life-long, rewarding pursuit, but we also know it fits into a larger context of healthy diet, sleep, lifestyle, and fitness choices.  Incremental changes you can live with, while adjusting to training, can help ensure that this goal won’t be the end of your training, but just the start.

Clyde Wilson was a naval service member who enjoyed weight training and working out, when his doctor on the USS Carl Vinson informed him he was on the verge of needing medication for high blood pressure and cholesterol.  After making a transformative change in his nutritional habits, he went on to study chemistry and cell biology at Stanford and now teaches there and the University of California San Francisco Medical School.  In addition, he runs The Center for Human Nutrition and Exercise Science in Palo Alto, California.

This month, we asked Dr. Clyde to weigh in about the lethargy many runners struggle through after a long run.

1.  When many runners finish a big long run, often they report feeling extremely lethargic and low energy for much of the rest of the day, even after eating.  From a nutrition perspective, what may be going on here?

 Athletes need to replace their carbohydrate losses from training at a rate that their muscles are willing to absorb those carbohydrates.  If you burn 1000 calories in a workout, roughly 800 calories of which are carbohydrate, and attempt to replace all of those carbohydrates at one sitting, the over-flow of calories into your bloodstream will send more than half of it to fat cells, where the carbohydrate will be converted into fat. 

Therefore, eating enough calories is not enough. 

The calories have to go into lean tissues to actually help you recover.  Not eating enough is another way to fall short.  So the athlete has to eat enough carbohydrate, but spaced out over time or eaten with vegetables so that the carbohydrate calories enter the body at a rate muscle is willing to absorb them.  Protein helps re-build lean tissue but is unrelated to the feelings of lethargy after hard training.
