The 100-Mile Week: Should You Try It?

Training for a marathon requires more time and effort than most think. It is not all about just running. Getting your body to be able to reach 26.2 miles safely and injury-free requires several other components. The priority should be to make sure we can get to that 26.2-mile mark without getting injured, burnt out, or being zombie-like throughout the entire process. Besides running several days per week, training will require extra time for strengthening sessions, stretching and more sleep. Because of this, there are a variety of different training plans you may find that are a “minimalist” approach, which include the least amount of mileage per week that will get you ready for race day.

On the opposite spectrum, there are those hard-core marathoners who have been training for years and attempt those very high mileage weeks without a problem. The most difficult part of this type of high volume training is the amount of time it requires. If you have a regular work schedule and a family to tend to, the hours remaining in your day will just be for training and sleeping. Evidently, you must be okay with the sacrifice. For the regular person, a normal training plan will usually consist of 50 to 60 miles per week at the most, whereas high mileage would be considered 75+ miles. Scattered throughout the week with some days including a morning and evening run, it can definitely be doable.

What about the elite runners out there hitting 130 miles per week? It sounds crazy but there is a science behind this extraordinary mileage. The classic 100-mile week is something even the everyday hard-core marathoners try to achieve. Some may say it is completely unnecessary, and that may be so, but if research shows a benefit to getting you to that next level, it may be worth a try. Fifty miles per week probably feels hard enough when first starting out, so considering doubling up your training will most definitely seem impossible. The key to getting to this point is to gradually and safely increase the workload. And no, this training approach isn’t for everyone OR the only way to progress in distance running.

Why 100?

Running Economy

Well, training to hit a weekly mileage of specifically “100” miles is merely just to get to the triple digits, because in essence 95 miles will provide the same benefit. Several studies have been done on high volume training and have concluded that there are many benefits linked to improving running economy. Basically, this means the more miles you run the less your body will have to work during the race, allowing you put that extra energy into faster paces. This is due to muscle and tendons training to adapt to prolonged running. These adaptations lead to increased elasticity of joints including the ankle, which in turn leads to a more forceful and less vertical push-off from the ground with each step. This will save a good amount of energy over time.

Aerobic Endurance

The goal of marathon training is to get our bodies to be able to run far, and if possible, fast.. The higher mileage programs essentially increase the amount of mitochondria and capillary density in the body, as well as hemoglobin and red blood cells. The growth of these factors leads to more and better oxygen transport through the blood cells to the muscles. This is why marathoners are eventually able to run farther and faster over time. Once you train to run more miles your body will learn to use fat as fuel and store more glycogen, which means more energy will be readily available for when you really need it, like at the end of a race.

Resistance to Fatigue

When you go from running 50 or 60 miles per week to 100 miles per week, the majority of those extra miles should all be performed at a slow, easy pace. The lower intensity, high mileage prepares not only our bodies for long races but also our minds. When you ask someone who is not a runner how they feel about running 26.2 miles, they will most likely think it’s a crazy idea. That’s because our minds become just as fatigued at the thought of running for so long as our bodies do. Many of the training runs in a 100-mile program will be 10-15 mile easy runs, where your body will undergo uncomfortable fatigue and soreness at times. It is during these long, slow runs that we get our mind accustomed to this sensation so that come race day, we can push through it.

Should I Try It?

Training to reach a weekly target of 100 miles is definitely not easy, but it is doable. The difficult part besides the extra time and sacrifice it will require is the high risk of injury it brings. More time on your feet means more chances of both accidental injuries as well as overuse-type injuries. It is important to gradually increase mileage every week. This means setting enough weeks in your training cycle to build up to 100 miles with no more than 5-10% increases per week and low mileage weeks built in every few weeks. The most important rule is to listen to your body not only for signs of pain but also for symptoms of overtraining and fatigue as well. Along with the 100 miles should also be at least 7 to 9 hours of sleep each night and 2 to 3 days of strengthening exercises. If these components are possible with your schedule then incorporating this extraordinary mileage program can be attainable.

Cleaning Up a Diet Without Restrictions

I catch myself saying the words: “new year, new me” every single January for years, and I get a little annoyed halfway through the month. It’s not that I feel there is anything wrong with the saying—I just think I don’t give myself credit for how good I actually am with most aspects of my life, particularly my health. I run six days a week, lift weights, eat pretty healthy, drink lots of water, stay away from smoking and heavy alcohol, and I wear sunscreen everyday. Besides working on time management this year, which has been a true failure for me since I became self-employed (this will be a separate blog post very soon!), I’ve been wanting to focus on specific aspects of my diet that I have been ignoring for years. I say out loud it is mostly about my acne-prone skin issues, but there are so many other symptoms that I feel are linked to annoying food sensitivities that I have been refusing to address.

As For These “Symptoms”…

I don’t feel I have experienced many symptoms that affect my function on a daily basis, which is the reason why I’ve just ignored them for so long. The only thing that’s really bothered me during my adult life is my acne and melasma, which I feel and have been told is primarily hormone-related. I also regularly get bloating and less than regular digestive issues. Increasing fatigue over the last couple of years has more recently been my main concern, since that specifically has been affecting my strength, running, and daily concentration on my work. Just a few months ago I was diagnosed with borderline hypothyroidism, which is definitely related to these symptoms, but diet can play a large role in managing the condition and keeping my symptoms at bay. My goal is to try and delay the need for long term hormone replacement for this health problem.

Restrictive is NOT the Way to Go…

At least not for me. Last year I went ahead and took advantage of a big discount that was going on for Everlywell—the at-home lab test. I was interested in seeing what food sensitivities I actually have based off of their kit. I know I shouldn’t take this as 100% accurate, especially after doing my own research and reading reviews about the discrepancies between these" “at-home” tests and real allergy testing. I kept in mind that this option was not testing allergies at all—just sensitivities I may have when consuming certain foods. I honestly thought my results would come out to maybe a couple at the most and it was a list of 22 foods! Now, one of the reviews I received from a handful of Instagram followers is that the case for some of these is that the test picks up foods I regularly eat, rather than something in my blood telling me I’m actually sensitive. Therefore I took the results with a grain of salt.

This long list of foods includes almond, wheat, chicken, eggs, garlic, potato, and oats, among others. Surprisingly the only dairy foods that were on the list were mozzarella and yogurt. For a few years now I have tried to stay away from dairy products after the recommendation from a dermatologist, and it made a big difference in my skin and digestive issues. I totally thought this would be number 1 on the list of food sensitivities! Regardless, the list was overwhelming for me so I did not do what was suggested which is an elimination diet. With that many foods on the list, it felt restrictive to me, and when I’ve restricted food groups in the past, it only caused me to have intense cravings and then binge eat. I feel I never minded restricting dairy all this time because I really didn’t care for it to begin with. I don’t like cheese at all, can live without yogurt, have never really been an ice cream fan, and with any recipe that called for milk I was perfectly fine using the alternatives.

Ticking Off New Year’s Resolutions

Okay, so one priority for me as far as goals go for this year is to learn something new every day. So far, I’ve been successful, and one thing I’ve learned this year is about what in milk is really the culprit of digestive issues. It’s the protein! I thought it was the added hormones some farmers use on cows or the lactose, but it’s actually specifically the A1 protein. My parents are very obsessed with A2 milk, which is made from cows that only produce the A2 protein. Once I learned all about this I decided to give this brand a try. As many of you saw on my Instagram feed, I jumped on board and took a challenge this month to switch out my milk, and I’ve been so happy about the results. No bloating, no stomach aches, and NO ACNE! I highly recommend this switch if you are sensitive to regular milk! Oh yea—and right now you can enter to win free a2 Milk for a year and a Peloton Bike + 1 year membership. Click here!

What About the Rest of My Diet?

Well, this post is the start of my goal—attempting to dial in to my current way of eating and pinpoint what is playing a role in my fatigue. I know I can be better about limiting my frozen food lunches and packaged snacks I have been eating regularly for the sake of saving time, so this will be the first thing I tackle (as I write this, I am eating plant-based air-fried chicken tenders). I also need to get back to a regular eating schedule—this will help with energy levels. I tend to get bogged down by projects and forget to eat. This will require me to make time for meal planning and being more creative with quick snack options for my work day.

Tackling this goal in 3, 2, 1… I’ll keep you all posted! Make sure to follow along on Instagram for the latest updates.

Strategies for the Long Run

A recent running magazine included an article about a professional marathon runner and when asked what their favorite training workout was, they answered “the 20-mile long run”. The assumption is that most readers probably responded with something along the lines of “Are you kidding me?!”. For most runners, the long run, especially when it gets up to that 18-mile point, is dreadful. Yet, the long run is probably the most important session of the week. After all, the race is just one really long run.

It has been recommended in several training plans to perform the long run in a long, slow distance (LSD), which has several benefits for race preparation. Running at 60-70% of 5k pace for these long distances will over time increase glycogen storage in the muscles, which means more readily available energy. The body does this by depleting the glycogen in our muscles during the run, which will cause the body to adapt by storing more glycogen. Another benefit of the LSD run is the increase in oxygen provided to the muscles by the growth of capillaries, where the carbon dioxide-oxygen exchange occurs, and mitochondria, where carbon dioxide and oxygen are converted into energy. These physiological reactions to running are the reason runners get faster and last longer over time through consistent training.

One downside of always performing the long run at LSD pace is boredom. There are only so many routes we can choose to get 20 miles done. A good strategy for these runs is to break it up into quarters on your route and in your mind. For example thinking of 20 continuous miles seems like forever. Breaking it up into four 5-mile segments is more tolerable. This is a good way to run the actual marathon, too! Another downside to choosing LSD is the lack of adaptation to running at goal pace and practicing what really happens during a race.

Many marathon training programs include long runs with at least a few goal-paced miles throughout. The purpose of these types of training sessions is to practice running fast on tired legs to mimic what race day will feel like. There are a variety of options to incorporate goal-paced miles, but it is important to be specific when heading out for these sessions, as it can be very taxing on the body. As after a race, you do not want your body to need days of recovery following your long run. It is an ideal option to alternate between goal-paced and conversational-paced sessions each week.

Goal-paced long run sessions can make these ‘dreadful’ training runs more tolerable, and help the time pass more quickly. Below are some great variations to the long run to alternate throughout your training cycle. As mentioned previously, the interval sessions can be very fatiguing and should begin with a few repetitions and miles, and gradually increase as your fitness improves.

• Mid-run tempo: Run 3-5 miles at conversational pace + 3-5 miles at goal pace + remainder at conversational pace

• Mile repeats: Run 3-5 miles at conversational pace + 3-5×2-3 miles at goal pace with 1-3 minutes at easy pace in between + remainder at conversational pace

• Fast finish long run: Run 75% of the long run at conversational pace + 25% at goal pace. As your fitness improves, build up to 50% at easy pace and 50% at goal pace

• Ladder: Run 3-5 miles at conversational pace + intervals of one to five minutes at goal pace with one to two minutes easy in between each + intervals back down from five to one minute at goal pace + remainder at conversational pace

• Ladder progression: Run 3-5 miles at conversational pace + 4 miles at goal pace+15sec + 3 miles at goal pace + 2 miles at goal pace-15sec + 1 mile at goal pace-30sec, all with one mile at easy pace in between. The goal of this progression run is to begin the first interval a little slower than goal pace, the next segment at goal pace, and then the last two segments of two and one miles even faster, finishing that last mile at a fast tempo pace.

These five workouts are great for building stamina and strength, as well as practicing your desired race pace, especially when your legs are fatigued. Alternating between options such as these with conversational-paced runs will ease your mind when preparing for long runs. The LSD run every other week will reduce the stress on the body and help recover faster than the goal-paced long runs.

In a properly organized marathon training schedule, you will find many different workouts spread out throughout the week, which all serve a purpose. If your goal is to simply finish the race, you technically can skip all of the speed sessions and tempo runs and perform all runs at an easy pace. If you skip the long run session in the training plan, you would have a very difficult time finishing the race. Therefore, the long run is the most important session of the week. The variations mentioned above may leave you somewhat near exhausted, but completing them will be a great asset to getting comfortable at your goal pace and enhancing confidence going into your races.

Sick While Tapering? Here’s Why & Ways To Prevent It

Training for a marathon requires several months of hard running, at least decent nutrition, and adequate sleep. The last two to three weeks are extremely important to the training cycle, as it is when the body prepares for race day by enhancing recovery while maintaining the fitness gained throughout the prior months. The goal of this taper period is to get the body to a more relaxed state and fueled for race day. To reach this goal, there should be a gradual drop in mileage and heavy weight lifting, and a focus on proper nutrition. Many runners use this time to lounge on the couch and go overboard on the carb-loading, but it should be more structured than that! A drastic change in routine during the taper is not such a good idea because the body has been used to tackling loads of miles and exercise and a diet to sustain that activity level. It may shock the body and possibly cause illness. The common occurrence of illness during the taper period may be due to other reasons as well.

Overtraining Syndrome

Studies have been done to assess the response of the body’s immune system to physical activity. There is not much evidence to conclude that properly trained and recreational athletes are more susceptible to illness than non-athletes. However, there seems to be an effect on immune function with prolonged intense physical activity. The strongest correlation is the susceptibility to illness and the over-trained athlete. Overtraining syndrome is when there is insufficient rest with a high volume of physical stress, and many times this is combined with other stressors such as emotional, nutritional, and environmental stress. If this pattern continues, after a certain time chronic fatigue will set in along with poor recovery.

Low Plasma Glutamine

Over-trained athletes often present with low levels of glutamine in the body. Glutamine is an amino acid that is responsible for the healthy functioning of lymphocytes, which are the white blood cells that keep our immune systems working properly. With low levels of glutamine, athletes who are undergoing intense physical stress, as in overtraining syndrome, are more susceptible to infections. Although the main focus to prevent a drop in lymphocyte function is to avoid developing overtraining syndrome, glutamine supplementation is an option to keep levels where they need to be.

Post-Exercise Immunosuppression

There is a drop in some aspects of immune system functioning following exercise, especially intense exercise, such as a long cycle or run. This window of opportunity for infections can last between 3 to 72 hours. Some studies have shown that over-trained athletes who have a combination of stressors may extend this window even longer than a three-day period. This may be a reason why illness arises during the taper period. Our hardest training is performed right before the taper begins and with a window of opportunity extending to three or more days, we are more susceptible to falling ill. This is where proper nutrition is key. It is beneficial to have a wholesome diet full of the essential vitamins and minerals the body needs to lower our risk of developing infections.

Tissue Damage

Intense exercise causes tissue trauma that triggers higher levels of cytokines in the blood due to chronic inflammation. Elevated cytokines will causes a suppression of certain lymphocytes that are responsible for immunity. This occurs mostly in over-trained athletes who do not recover properly. A protective response of the body is automatic behaviors that will lead the athlete to decrease training intensity. This is due to the communication of cytokines with the brain to induce mood changes and fatigue.

Taper Illness Recovery & Prevention

The first plan of action to prevent taper sickness is to avoid falling into overtraining syndrome. Throughout the several months of training it is vital to incorporate enough rest time. Not every body is the same. Some tolerate less recovery than others. It is important to keep in mind that without proper recovery, our bodies cannot perform at their best. As mentioned above, good nutrition should also be a top priority every day during training. A diet full of essential nutrients and vitamins is key to keep our bodies working properly, as well as maintaining a low risk of acquiring infections.

If you are reading this while you are already sick and in the midst of your race taper, then the best action to take is to get plenty of rest during this time and drink a good amount of fluids. Nutrition is extremely important during illness, as our bodies require more energy to assist in the healing process. Appetite may be low or nonexistent during sickness, but it is vital to make sure to eat enough calories and make sure it is all from high-quality foods! The taper will require continued training runs at a lower intensity and volume, but if your illness consists of fever, body aches, and chest symptoms, it is best to take a few days off from physical activity. If symptoms are from the neck and above, such as a runny or stuffy nose and headache, it is usually safe to head out for easy runs. Remember, the taper period is not meant to improve performance and taking a few days off will not lower your fitness levels. Forcing running during this time while you are sick may only prolong your illness and negatively affect your race day outcomes.

Beta-alanine & Exercise Performance

Runners, like many other athletes, are constantly looking for safe ways to improve their running performance. Whether it be training in certain environmental conditions like in the heat or at altitude, or changing their fueling methods, there are many strategies one can use to get faster and last longer. The key to seriously improve performance is to understand where you are lacking in the first place. Is it too little muscular strength that is holding you back from running with good form? Or maybe you are actually pretty strong but endurance is what is weak. In many cases performance is hindered by poor nutrition, especially before and during exercise. For some runs it may be just fine to go out on an empty stomach but if you want to run hard and for a long period of time fueling the body efficiently is important.

Supplementation

It is common for athletes to supplement their diets with nutrients they may be missing out on in their regular meals. Runners supplement with electrolytes and other vitamins that are important for proper organ function and recovery from training. Protein powders are probably the most common supplement athletes consume, as it is essential for muscle repair and growth. The building blocks of protein, amino acids, are important in the diets of athletes since during hard exercise muscle fibers go through microscopic tears and require these essential amino acids for the repairing process. 

Beta-Alanine

One amino acid that is actually considered a non-essential amino acid, called beta-alanine, is a commonly used supplement in the sports world. The reason it is considered a non-essential amino acid is because it is not involved in protein synthesis, as are the others. Beta-alanine produces carnosine, a substance that is stored in the muscles and reduces lactic acid accumulation. This lactic acid buildup is produced in the muscles during exercise and is the reason why our bodies require recovery time in order to be ready for another session. If less lactic acid is building up in the first place than recovery time will be shortened. This is the main reason why beta-alanine is being used to improve performance.

*exercise image

During lactic acid accumulation, excess hydrogen ions are produced in the muscles, causing a drop in pH levels—meaning they are now in a more acidic state. This acidity blocks glucose breakdown, which is normally what fuels our muscles, causing less muscle contraction, and eventually fatigue. The carnosine produced by beta-alanine is what maintains a normal pH level in the muscles during this process, therefore lowering the risk of fatigue. This benefit of increased time to exhaustion helps runners and other endurance athletes last longer. 

How Does Beta-alanine Help Marathoners?

Studies have shown that these benefits are more evident in short bouts of high intensity exercise lasting between one and several minutes. This means speed session consisting of 400m to mile repeats can be greatly improved with the use of beta-alanine supplementation. Although marathon running is commonly looked at as a low to moderate intensity exercise, the fact that you have to run at a fast goal pace for several hours requires specific training at significantly high intensity. This is where those short bouts of intervals come into play for marathon runners. Strengthening those fast twitch muscle fibers through speed sessions that can benefit from beta-alanine supplementation will lead to maintaining that goal pace you desire on race day.

Diet, Supplementation & Dosage

Most people who regularly eat animal protein get a sufficient amount of beta-alanine. Beef, pork, chicken, and fish are the main food sources of this amino acid. Regular servings of these proteins will contain between 50 to 250mg of beta-alanine. Most research advises to have between 2 and 5 grams per day to reap the benefits of carnosine production. Over the course of 4 weeks, carnosine concentration can increase by up to 40-60%. Combining the supplementation with a meal has been shown to enhance the production further. After one month of supplementing with this amount, the dosage is then lowered to half. Beta-alanine does not have to be taken at a certain time in order to gain the benefit. Some athletes combine it with their pre or post-workout drinks, but it can be included with any meal.

Supplementing with beta-alanine has been shown to be safe and effective at improving endurance and decreasing muscle fatigue during exercise. One common side effect that may be experienced is paraesthesia, which is a tingling sensation usually noticed in the face, hands, and neck. This effect is usually mild, short-lived and occurs during the first few times of taking the supplement. Carnosine production decreases by 15-20% from youth to adulthood, which suggests that beta-alanine supplementation may be even more beneficial for older athletes. As with any other supplement, it is advised to talk with your medical doctor before including anything new in your diet. Although beta-alanine is safe and shown to be effective, studies have not concluded its effects on athletes with any specific medical condition.
