(Edited by Brad Minus) The Decision My 3 years of running experience started with multiple injuries including a couple of ankle fractures. However, I still managed to complete a marathon, a 50K and...
I can hear it now….”Know wonder they call you a Goof…you are crazy.”, “So, if I run slower I will get faster? You are out of your mind.” It was not to long ago I used to think the same thing, but as with everything I post, there are reasons and science to back it up.
Let’s face it, logic would dictate that pushing the pace of your easy days, as close to race pace as possible, would help you get fit faster and help you speed up, right? A lot of coaches, including myself, will tell you to run slow on your easy days, and easy days should be making up anywhere from 50-75% of your weekly mileage.
I have clients continuously asking me, “why are my easy days so slow?” The latest is my famous sit downs with my runners telling them to slow down after examining their data and finding them running tempo speeds during an easy day.
The answer to the question is what Arthur Lydiard and most other coaches would call the aerobic system. The aerobic system, or aerobic development, is the one of the most important fundamentals into unlocking your true potential.
Let us first check the stats on the energy contribution the aerobic system provides for races. As you can in the chart below, even the shorter events like the mile, over 80% of the energy required to run the race is produced via the aerobic system.
Aerobic System? What is it?
Aerobic training is the scientific fact that to move your body at higher intensities, the body needs to break down sugar and convert it to glycogen so it can be used as energy.
The aerobic system plus oxygen starts a chemical reaction known as Aerobic Glycolysis which continuously powers continuous endurance activities. In the aerobic system energy ATP is produced through Pyruvic Acid and Lipid/Protein fragments entering the Kreb Cycle and the Electron Transport Cycle.
During aerobic respiration (yeah, that’s breathing) the body uses all the oxygen it needs to power the muscles. When you are running in your “aerobic zones” (easy runs), your muscles have enough oxygen to produce all the energy they need to perform.
See? Improving your capacity to transport and efficiently use all the available oxygen to produce energy will enable you to race faster since this makes up 85-99% of the energy needed to race.
Since running easy is aerobic development, what better way is there to train the aerobic system? There is none.
What goes on in the body during aerobic development?
Capillary development – capillaries are the smallest of the body’s blood vessels and they help deliver oxygen and nutrients to the muscle tissues while exporting waste products out. The larger the number of capillaries you have surrounding each muscle fiber, the faster you can transport oxygen and carbohydrates to your muscles.
Aerobic training (easy running) increases the number of capillaries per muscle fiber, thus improving how efficiently you can deliver oxygen and fuel to your working muscles and how quickly they can clear waste products.
Myoglobin is a protein in the muscles that binds the oxygen that enters the muscle fiber. When oxygen becomes limited during intense exercise, myoglobin releases oxygen to the mitochondria to produce more energy.
The more myoglobin you have in the fibers of your muscles, the more oxygen is transported under aerobic stress. Like, uh, during a race. Aerobic training increases the amount of myoglobin you have in your muscle fibers.
Mitochondria are microscopic organelle found in your muscles cells that contribute to the production of ATP (energy). In the presence of oxygen, mitochondria breakdown carbohydrate, fat, and protein into usable energy.
Therefore, the more mitochondria you have, and the greater their density, the more energy you can generate during exercise, which will enable you to run faster and longer.
Aerobic training increases both the number and the size of the mitochondria in your muscle fibers.
Suffice it to say that aerobic development is the single most important factor to long-term development.
Of course, track workouts, VO2 max sessions, tempo runs and cross training will increase your fitness and are still incredibly important to racing faster. However, nothing will help improve continuously like developing the aerobic system.
Aerobic development is dependent upon running in your aerobic zones (for my runners Zones 1-3). This is why running faster on your easy days develop the aerobic system. Once you step out of those aerobic zones, on easy runs you diminish development of your aerobic system, but you also increase the chance for injury. Nope, two negatives do not make a positive in running.
This is one of the single biggest mistakes runners of all experiences make in their training.
As a coach and trainer I have always distinguished myself because I am always able to give my clients and readers the “why”. (Sometimes my clients end up telling me to just shut my mouth. when I am training with them because I am continuously telling them why they are doing each movement of an exercise or workout. I guess it may not be an advantage all the time. Go figure.)
Optimal Aerobic Development
Scientific research has been able to identify how the aerobic system adapts and responds to certain training paces. Physiologically we know:
- Capillary development appears to peak at between 60 and 75 percent of 5k pace.
- Maximum stimulation of myoglobin in Type I muscle fiber (Endurance Muscles) occurs at about 63-77 percent of VO2max. 63-77 percent of VO2max is about 55-75 percent of 5k pace.
- Two researchers, Holloszy (1967) and Dudley (1982) published some of the defining research on optimal distance and pace for mitochondrial development. In short, Holloszy found that maximum mitochondrial development when running at 50-75 percent of V02 max. Likewise, Dudley found that the best strategy for slow-twitch, mitochondria enhancement was running for 90 minutes per outing at 70 to 75 per cent V02 max.
It is pretty clear now right? Your optimal easy run pace for aerobic development is between 55 and 75 percent of your 5k pace, with the average pace being about 65 percent.
It’s also evident that running faster than 75% of your 5k pace on your long run has very little additional physiological benefit.
In fact, the research indicates that it would be just as advantageous to run slower as it would be to run faster. Running around half of your 5k pace is pretty easy right? Wouldn’t you know it, the evidence is clear that it still provides near optimal aerobic development.
Feel free to let me hear your feedback. I welcome any other case studies, personal experiences and other research as I am always learning. I provide you with the best content I can, but I have an open-mind and know that there may be other research out there that may negate information I post.
Hey there boys and girls, guys and gals. It’s the Goof comin’ at ya from Tampa, Florida to give you the first episode of what I hope to be one of many.
The Goof Views and News.
These will be personal perceptions made during specific times or events that may resonate some of you and news of events that have happened or will happen in the future. For instance, as I have posted on FB and Twitter, I have registered for the Chicago Marathon as I did in 2011 prior to the Florida Ironman. Ta da! The first news of the post.
The Views (Seeing through the eyes of the Goof)
I was at Disney World this weekend enjoying some rest and relaxation and I wouldn’t say it was an epiphany, but it was a clarification of sorts. I just happened to be in line at Buzz Lightyear in Tomorrow Land when I saw a couple coming toward me. He was a larger man riding in one of those motorized carts, and she was walking beside him. She wasn’t a small person either. They obviously were not concerned about their conversation being overheard and I heard him swear at her for some reason. She yelled back at him, “Well if you would do something about it, you wouldn’t have to ride around in that thing.” He snapped back with, “You think it is that easy, well you try it.” She ended up retorting with, “I am! You <insert explicative here>! You don’t see me needing a <insert another explicative> wheelchair. Do Ya?” The large man pushed what I assumed to be the accelerator and moved ahead of her.
This is what I recall, it may not have been their exact words, but it did make me look around a bit more during my weekend visit. Without being completely rude I started focussing on the more obese adults and I noticed something. Ninety-five percent of the adults that were obese looked miserable. I am not including people that just had a few extra pounds on them, I am talking about adults that were obviously fat.
There was not one of them that looked like they were having any fun. Here we are in the happiest place on earth, with perfect weather, scents of food, and sweetness in the air, upbeat music, not a noticeable speck of negative energy in the place and these people are miserable. Why would anyone want to do that to themselves? Don’t get me wrong, I have never been that big. I have been fat where I needed to take some pounds off, but never obese, so I can only imagine how hard it is, but to willingly stay in misery, just sounds exhausting to me.
Later, I sought out children that were, let’s just say, were in need of some more activity, which took all of thirty seconds. While there were some that were running around, in my estimate, seventy to eighty percent of them were whining for somewhere to sit down. Sit? When there are rides, and new things to touch, smell and see? Of course, most of them had parents that were in the same condition. Go figure.
There are articles on articles explaining the epidemic we have in this country of obesity, but they are words on a page and maybe a picture. I was able to watch this before my very eyes and they burned with disgust, pity, and sadness. The next morning, I got up and ran six miles to clear the images from my head and come up with some kind of dream resolution. The next time you are at an event or a place where there are families and a lot of people become aware of this. (Athletes: the Gasparilla Distance Weekend coming up, would not be a good place for this kind of perception.)
After mulling this around for the last few days, my desire to help has increased. I know there are an abundance of people with this same desire and some of them more so if they have been able to overcome this obstacle for themselves, but I really want to help and the kids even more so. We need to bring this epidemic more into the open and encourage people to move around and do something for a minimum of 20 minutes a day.
On to the News
I have entered into a partnership with Brenton Ford from Effortless Swimming. He has a new program called Swimprove where a swimmer can log into a website and access an abundance of material to help them swim faster and more efficiently As I have stated in numerous posts before, I really need help on my swimming.
I will be accessing his website and will be following his advice to the letter and bringing you my results, epiphany’s and observations. This program of Brenton’s is not just for beginning swimmers, but for triathletes, open water swimmers and masters swimmers that would like to improve and become faster. Included is not freestyle but the butterfly, backstroke, and breaststroke as well. I am really excited to get started and document what I have learned.
Gasparilla is this weekend and I am taking on the Beck’s Lite Challenge, so I will be running the 15k and 5k on Saturday and the half marathon on Sunday.
Which races are you running?
I am currently coaching at FitNiche on Tuesday’s with a new program called the Technical Tune-up. I have a number of runners just looking to have a structured workout that includes warm-ups, and cooldowns and gives them access to a coach running with them paying close attention to their form in order to create more efficiency and keep them injury free. Most of my runners are return clients, but I do have some new clients that have joined the flock. I am really excited to be coaching again. The program goes for 8 weeks and then renews. I still have some slots available, so if you feel like you are getting injured a lot or just not making any progress, or just want a structured workout, come on out. Tuesday Nights starting at 6:30 pm at FitNiche in Hyde Park Village.
The owner and I are working on the marketing for a new course as well, but I will announce that later when the details are flushed out.
That is it for this episode of the Goof Views and News. Have an amazing week and train hard athletes, but also train smart.
I thought it was kinda nutty when I was invited to the Sunrise/Sunset Challenge, but I wasn’t sure the impact it would have on me. I looked at the distances of the two races, Top Gun and the Twilight Triathlons, and thought, “What the hell? The two distances do not even add up to an Olympic. How difficult could it be?” What I didn’t count on was the increased effort level?
The plan was hammer the Top Gun and do the Twilight for fun. (I am a poet and didn’t even know it.) Yeah. Right. Considering I have been competing and training for more long course triathlons lately, I really thought I would finally be able to conquer the sprint. My last full sprint was two years ago, when I competed in a few sprints in order to get ready for a marathon my times were less than admirable. To be honest, I was happy with 1:20 at the time. Now, after a few Ironman 70.3s and last year’s full Ironman I really thought I could do a lot better. Figuratively, I actually did, but in my mind it still wasn’t what I wanted, but there were some small achievements.
I picked up an A-Train Tri member, Jaime Breibert, around 5am and headed out to Ft. DeSoto. After the experiencing the pay-to-park line for the Escape from Ft. DeSoto Triathlon, I was pleasantly surprised this event was exempt so there were no delays driving into the park. Nice! Like every other race I have competed or watched at Ft. DeSoto the organization of the event was outstanding. The line for body marking was minimal, the transition area was large enough to accommodate all of the athletes bikes, space for their transition setup and extraneous bags. Walking into transition I spent minimal time setting up my bike, helmet and sunglasses, towel, bike shoes, and running gear including my choice of shoes (this time being my Brooks Pure Cadence), running belt and hat. I wasn’t rushed for time, or inconvenienced by other athletes. It was smooth sailing which is always nice since it eliminates any unwanted stress.
I headed on down to the beach with Nick Zivolich and Jaime where the low pitched but high energy voice was repeating instructions over the speaker system. It was a nice and comfortable environment I have come to love over the past years. The energy of the upcoming race increasingly becoming more and more intense as the time for the first heat was getting closer. I caught up with a bunch of friends and familiar fellow tri community members I have accumulated over the last years. This is absolutely one of my favorite times of the race. I have been really lucky this year as my age group has been assigned early heat times, so the intense anticipation has been minimal. Last year, I was not so lucky, but I understand the race directors strategy of moving the groups around each year to be fair. It will be interesting to find out what they where I will be starting next year. I was in the fifth heat this year only 12 minutes after the first and immediately following Jaime’s heat.
I wished Jaime and Victoria luck and intensely watched them swim out to the first buoy. Just a quick disclaimer. I totally and utterly suck at swimming. For me triathlon is survive the swim and get on the bike where the competition really begins. Not that I haven’t been working at it, but honestly, if for some reason I have to skip a workout, I’ll skip a swim before a bike, run or strength workout, but I digress. The horn finally went off and my personal race had started. I had been analyzing my swim prior to this, and just recently had the epiphany that maybe my pull of my arm through the water was possibly to shallow to allow me any kind of real speed. I usually finish with the heat behind me, and even sometimes with the heat behind that one, but this time following my experiment of dipping my arm deeper and pulling a little harder, (Voila!!) I actually finished in the middle of my heat. As I ran to my bike I noticed silver swim caps in front of me and coming behind me. A huge smile came over my face as I was slipping into my bike shoes and put on my helmet and sunglasses. I really couldn’t believe it. At this point I already felt like a winner.
I ran out of transition, jumped on my bike and headed out to the course I knew so well, due to all of the brick workouts I completed here with my A-Train Triathlon family. My goal; keep my speed above 21 while keeping a cadence under 96. The whole ride was pretty uneventful. The same word came out of my mouth more than anytime in the short period I have been racing. I continually yelled the word “left” as I was passing other athletes on my right, of course it was disconcerting when I heard it coming from my left. The ego boost came when I finished the final roundabout yelling “left” to a male athlete that had passed me at the beginning of my ride. As, I came into transition the only thought was how fast can I get in and out of transition, start the run and whether or not I had pushed a little to hard on the bike. According to my computer I had averaged well above 21, so was that too much?
I pulled on my shoes, grabbed my hat and ran out of transition buckling my race belt with my number attached to the front. I grabbed water on the way, a little disappointed when it turned out to be very warm, but it was wet. As I started trying to increase the cadence I noticed that my legs were very heavy, not a good sign. I kept saying to myself this is fine, just lean from the ankles and let gravity fuel your momentum. As much I told myself to lift my legs and lean a little more, my body refused to submit to what my head was commanding. I continued through the first mile to the fort, and very, very slowly my legs started to loosen a little, and my cadence started to increase. Passing the 1 mile aid station, I noticed a little more energy in my step and my hip flexors obeying my will. Then I turned the corner and I remembered. Crap! The middle mile of this race is on SAND! The lower extremities of my body surprised me as they adapted immediately to their new environment. I guess all those beach runs with Amy Eck had actually done something for me. All of the sudden I found myself enjoying the run. My legs stretched out, by body leaned, my cadence finally reached 180 (I think) and I was flying. Who would’ve thought feeling all that resistance under my feet would actually transform into moving faster? Not me, but after begging my body to obey earlier I was not going to look a gift horse in the mouth, so before my body decided any differently I picked up my pace. Turning on the path back to the asphalt I caught another athlete with a 44 on his calf. Hmm…an athlete in my wave I will place in front of…cool. With that thought completed I noticed another male runner in front of me with the number 41 on his calf. My only thought; “You are mine!” With the finish line in sight and the 3 mile marker on my left, I started to sprint with the finish line getting larger in my view and the runner in front of me coming closer and just a few feet from the timing mat, I caught him and jumped in front. A short term goal accomplished. I was so wiped out I could not immediately put my foot on the stool in order for the volunteer to remove my chip. I had to step over to a section of baracade and keep myself from falling for a quick second. After a half a minute I recovered enough to get my chip removed, grab some water and meet some friends at the end of the finish line assembly. Jaime had just finished and Speedy Nick was there already dried off and drinking some water.
With as exhausted as I was how was I ever going to this again in less than 12 hours?
After greeting some friends and coaches, watching some other friends and athletes come across the finish, I headed out to find some water and Gatorade. I noticed some preliminary results were posted, so I walked over in the hopes mine might just be posted and as luck, good or bad, would have it they were. My first split was the swim, and I was pleasantly surprised 7:53…cool. Less than 2 min per 100m…I’ll take that considering my miserable swimming performances leading to this race. Second split was the bike..26:51 averaging 22.3 MPH…Sweet! I never did that before. Finally, a 26.35..5k run. Well, I have run much faster, but not during a triathlon. 8:33 miles per minute…honestly I thought I did better, but I accepted it. More Bricks, more bricks, more bricks.
Overall, 1:06:36. A personal record(PR) since my last Sprint was 1:19 so you would think I would be happy and at first I was, until I looked at my place; 38th with only 67 athletes in my age group. Not even in the top 50 percent. That dropped me from my high pretty fast. There were still runners on the course so maybe there a few more in my group out there where I can at least be in the top half. As I check the results while I write this, it turns out there were I am ranked 39th out of 84 so I made it, just barely but I did make the top half.
The end of the morning consisted of congratulating friends, socializing and grabbing some breakfast at Lucky Dills in downtown St. Pete. I couldn’t have imagined a better morning.
Next up, the two race day continues.
