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.

My Journey to Fast Running

Fast race times are not just for the pros. Anybody can train to improve their speed as long as they put their heart and soul into running and find the right plan for themselves. Some runners do better running every day or with high mileage plans, while others do best with minimal miles and more rest days. For me, it took some trial and error and lots of research to get faster. I am questioned almost every day on how I cut my race times in such a short period of time. It did not happen overnight. I put in a good amount of work and a part of my passion is to share my story in hopes that my tips help so many of you!

Once Upon a Time, I Ran ONLY for Fun

First of all, my initial BIG improvements had much to do with the fact that I was not focused on getting faster AT ALL during the years I was racing before I decided to make this my goal. I’d been a runner since 4th grade, participating in cross country and track and field on and off until I graduated from high school. I kept running in college only because I hated the cardio machines at the gym, and running was just something I knew how to do that was outdoors. A friend of mine suggested signing up for a half marathon, which I thought was crazy at the time, but she promised me that one day running 13 miles was going to feel like what 3 miles felt like back then. She was right. I signed up for the 2009 Miami Half Marathon and was hooked, but not how I am hooked now. I did not pay attention to finish times or pacing or anything that has to do with improving at the sport. All I cared about was staying in shape and the excitement of the races once a year.

This is how I treated running up until 2016, when I randomly put on the Olympic Marathon Trials after reading about it in a Runner’s World Magazine. This was about 2 weeks after finishing my first Miami Marathon in 3:53. All of a sudden I got the urge to get faster—I figured, I actually like to run, I’m not bad at it, and the training plans I read in the magazines all seemed doable to me. A few weeks later I raced the Miami Beach Half Marathon and got my best time, 1:44, which I attribute to the motivation and adrenaline from my new found passion. That same week I bought a Garmin watch, new shoes, and signed up for the Ft. Lauderdale Half Marathon in November. Within those 8 months I spent hours researching training plans, advice and every amount of information I could to implement into my new venture.

More Miles Works

I went from running at comfortable paces 3 days a week to running 5 days, which included my long run and a speed workout that I would switch up every week. I believe it was the gradual increase in mileage and added speed work that got me a 9 minute PR in the half in only 7 months time! I was nervous to run more than every other day thinking I would get injured, but from everything I researched (and my research only comes from scholarly written studies, as I was taught in school—haha), I learned that as long as you SLOWLY add in the miles, keep it easy for the majority, and continue strengthening exercises, it can most definitely improve race times. This 100% worked for me. I ran the rest of 2016 getting up to an average of 75 miles per week.

I had already been a physical therapist at this point for 5 years, so I was super strict about injury prevention, recovery, and paying attention to my body. I raced the Miami Marathon in January 2017 and finish in 3:22—a whopping 31-minute PR! Of course, like the rest of us, I wanted more. After more research I decided to attempt the daunting 100-mile week before my next full marathon, but I knew this was going to come with some sacrifice. More miles = more sleep/downtime, more eating, and more recovery sessions. My baseline training over the summer that year was around 60-65 miles per week and I gradually added in more once the fall came around to hit 100+ miles for 3 weeks before I tapered for the race in January 2018. I cut another 16 minutes off of my PR that race. My half marathon PR came 3 weeks after that one where I cut 8 minutes from 2017.

After falling for the comments on how I wouldn’t be able to keep this up on my own, I decided to try out a coach, who initially kept me at decent mileage (although still 75% of what I was doing when I was at my best), and then dropped the milage down to 40 miles per week by the end of 2018. This actually got me out of shape and my streak was over. Since starting back up on my own this year I have gone back to my previous training plan, with much more updates, and finally feel back to my old self with even BIGGER goals!

2015: 35 miles per week —> 3:53 full / 1:44 half

2016: 75 miles per week —> 3:22 full/ 1:33 half

2017: 100 miles per week —> 3:06 full/ 1:25 half

2018: 70/40 miles per week —> 3:14 full / 1:33 half

2020: 90 miles per week —> 3:03 full / 1:24 half

Varied Speed Work

I spent the summers incorporating short speed sessions—200-800 meter repeats and Fartlek runs. During my actual marathon training, my speed sessions varied every week. I alternated between mile repeats, continuous 200m on/off 10ks, Yasso 800s, and progressive ladder workouts at the track. I rotated between these workouts every 4 weeks and was able to see improvements in each once a month when it was time to repeat them. Since 2018 I’ve learned all about the benefits of longer intervals for distance running (which intimidate me!), so that’s what I’ve been incorporating these days with amazing results. My best seasons are those where I’ve managed to stick to one track session of shorter intervals and one tempo run each week. The rest of my running is all EASY paced. Click here to see a few examples of my go-to speed sessions.

LOTS of Eating

It’s a good thing I love to eat, because marathon training allows me to eat twice as much as I used to! When I was training early on, I believed I could eat whatever I wanted. That is the most untrue statement for runners. First of all, we don’t burn as much as we think—in an hour-long run I burn around 350-400 calories. That’s probably just about a slice of pizza! Second of all—if you want to improve your performance, you must think of food as fuel, rather than pleasure…at least 90% of the time. Following a high-quality diet of the right amount of macros and calories will keep your body at a healthy weight, help you last longer during any run, and help prevent injury. In my opinion nutrition plays a bigger role in performance improvement than anything else. Once I started increasing my calories, especially carbs, I saw a massive spike in energy, better sleep, and more strength during speed sessions. Mid-run fueling switched from an intake of 200 calories (a pack of PowerBar chews) during an entire marathon, to over 1200 calories! This was a game changer for long runs and races—I am never exhausted afterwards like I used to be.

Quality Recovery

Recovery has many different sides. It includes sleep, elevating the legs, use of compression, icing, stretching, massage, physical therapy, foam rolling, and full rest days. It sounds like it requires so much time, and it does, but without these components, you risk being able to run more, hit paces, and recover from workouts quickly. This is probably my weakest area. If I skip something one day, it’s usually not my runs, strength training, or eating. I used to skip stretching, go to sleep late, and sometimes walk around too much on my complete rest day. Now, I am slowly learning to prioritize recovery—going to bed earlier, using my Normatec compression boots, getting a massage every few weeks, and stretching after every run. Since being more strict about this, I rarely get sore or feel fatigued legs on my runs—and I’m running around 90 miles per week right now!

Make Time for Cross Training

During the off season I was going to the gym 4-5 times per week for at least 45 minutes. Of course as I start to run more, I shorten my gym sessions, but make sure they stay high-quality and that I hit every muscle group. My workouts are mostly full body sessions, with a big emphasis on all core muscles, at least 3x per week. I NEVER skip the strength training—I remind myself of the time I was injured and how horrible it felt, and that is enough to get me to do the work. I also make time to go for walks and use the stationary bike—this will only be a couple times per week for 20-30 minutes.

This is MY Plan, Not YOURS!

As I mentioned in the beginning, adding in all of these components is totally doable for anyone. The only obstacle most people have is lack of time, but with a little sacrifice, and shifting of your schedule you can find time for each and every one of these components. The one thing you don’t want to sacrifice in order to add more miles is sleep—it is VITAL if you want to run well. You don’t need to run every day, and it’s actually okay to not have a full rest day. You just have to make sure at least 75-80% of your runs are easy. If you are stuck and unsure about how to structure your training to get results, a coach may be the answer—even if it’s just for one season. Don’t hesitate to reach out to me with any questions or if you’d like to join my team and have me be your coach!

READY, SET, GO... Miami Marathon Training in Full Swing

Here goes another marathon training season! I am already looking forward to my next full marathon—Miami Marathon in February 2020. My 20-week cycle starts today and I am fully prepared for what these next five months will bring! I use a longer training cycle than most because I am a high mileage runner, so I like to have more time to get to 100+ mile weeks. I make sure to stick to no more than a 10% increase each week, with a few lower mileage weeks in the mix. So far, throughout the summer, I’ve kept my mileage around 65 on average, but have had a more unstructured program. I’ve basically kept most runs easy, with some hills sprints every week or so, and some tempo miles when I’ve had to use the treadmill. Now the fun part begins—STRUCTURE!

My Plan

The difference between the on and off-season for me is not only the fact that I run more in the on-season, but I also eat a little better, stay more on top of my supplements, switch up my strength training to more calisthenics and body-weight exercises, and recover a whole lot more! For the next couple of months, my running program will look a little like this:

Monday:          AM: Tempo + hill repeats

                         PM: upper body + core workout 

Tuesday:          AM: Easy/recovery run

                         PM: Easy run

Wednesday:    AM: Medium long run

                         PM: leg + core workout

Thursday:       AM: Easy/recovery run

                         PM: Easy run

Friday:             track workout + leg/core workout

Saturday:        long run

Sunday:           optional recovery run or other cross-training

I’ll increase my mileage for some of the easy runs and the long run of course. After a couple of months, my tempo and track days will get longer as well. 

Nutrition

No matter the time of the year, my diet looks pretty much the same. I eat relatively healthy overall, limiting “crap” food throughout the workweek and try to stick with one “cheat meal” on the weekends. I don’t stress about having a strict diet—I actually worry I am not eating enough sometimes! The biggest difference I make during marathon training is increasing my calories...if I were to count, this would probably be around 3000 calories per day. I focus on eating high-carb and protein, and moderate fats, making sure at least 85% of what I eat on a weekly basis is “quality” foods. Here is a sample of what I generally eat in a day:

Pre-run:    Either a clif bar or Maurten 160 or 320 drink (bagel with PB before long runs)

Post-run/breakfast:   Smoothie with protein, cherry juice, beta alanine, beetroot powder, banana, berries, and chia seeds OR oatmeal

Lunch:    Eggs & toast, sandwich with turkey or tuna, or oatmeal if I didn’t have it for breakfast

Snack/pre-workout:    granola bar

Post-workout:      protein shake

Dinner:     lean meat/fish/chicken with veggies and rice/potatoes/pasta (usually 2 servings)

Dessert:     Either cookie dough or Justin’s Peanut/Almond Butter Cups

Supplements

I am good about taking my regular vitamins throughout the year, but try to be more strict about this during training, along with some additions. My daily dose of vitamins year-round includes: vitamin C, zinc, magnesium, fish oil, calcium, and iron. During training season I add in glutamine post-workout and beta alanine twice a day, evenly spaced out. Glutamine is great for keeping the immune system healthy and recovering the body. Beta-Alanine is used to help reduce lactic acid accumulation, which means less muscle fatigue. I’ll add in a blog post soon about these supplements!

Recovery

This is my hardest part! Sleep should be a top priority if you want to run well, but it’s the biggest challenge I have. I am a light sleeper so just about any noise, movement, or light wakes me up. I also have a hard time falling asleep. I take melatonin when I remember, so that helps some, but my goal this cycle is to gradually start getting to bed earlier so I can have a little more sleeping time! I have been using the ResMed S+ sleep monitor and it has helped so much! I track my sleeping patterns, so I am able to pinpoint what is most likely causing my poor sleep. My other recovery tactics are little things I do throughout the day like rest with my legs elevated every couple of hours and use my Normatec Recovery boots one hour per day. This truly helps prevent swelling in my calves and feet and keeps my soreness to a minimum every day! They are pricey, but worth it! Here is a less expensive brand you can try.

 I am hoping for a smooth ride from here until February. I will be documenting as much as I can, which will not only help so many of my readers with their plans and motivation, but it keeps me accountable as well! I will keep everyone posted if I decide to add in a race or two this Fall as part of my training. I’m thinking about joining in on the Turkey Trot fun and race my first ever 5k and maybe squeeze in a half marathon in December. We’ll see! Stay tuned.
