NYC Marathon: Goof Recap

If you didn’t have an opportunity to read the epic writing in the previous post, I discussed the reason “why” I ran the NYC Marathon, then I highly recommend that you do.  Not just because the writing was fantastic, but it is my hope that the recap will be more emotionally moving.

Delta carried us to New York City and back with no issues.  I was upgraded to the business class on my departing flight, and returned to Tampa in economy class.  Even with my average size, I felt extremely cramped in economy.  Scott and his six-foot-one-inch frame looked extremely uncomfortable.  It is obvious, that Delta increased their upgraded business class at the expense of the comfort of the economy class passengers.  My suggestion to anyone flying Delta to the NYC Marathon, just include the cost of the upgrade if the flight it over 3 hours.

The plans were made well in advance for room and board.  After each of us declared our opinions for a hotel of choice, one of our teammates found a condo in Chelsea that would accommodate all of us comfortably and provide a full kitchen to save a little money on meals.

Per an email from VRBO (Vacation Rentals By Owner) we were to pick up the keys at a local pizza restaurant located next door to the building housing the condo.

Team Tampa PKD arrived around 4 pm and the employees working that afternoon had absolutely no idea what we were talking about.  Of course, we called the management company and were basically told they did not receive the contract.  When we had the contract in hand we called the agency back but no one would answer our calls.

Here we were, in New York City, on marathon weekend, not to mention the third and fourth game of the World Series, homeless.

Teammate Kevin O’Brien to the rescue.  Kevin works for a landscape development company and happens to travel quite a bit, which was lucky for us.  With his Hilton Honors status we were able to procure two rooms at the Hilton Garden Inn located in Tribeca.  Thank you Kevin.

The rooms were updated, immaculate and comfortable.  Another, nice little value add of the Hilton Honors was the choice of extra points or free breakfast.  Kevin being the generous person he is, opted for the free breakfast for us which again helped save a little bit of money.  Again, Thank you Kevin.

With all of us now settled, we headed to the Javits Center to pick up our NYC Marathon packets.  The bibs numbered up to 72,999.  It still amazes me how easy it is to retrieve a bib, swag and t-shirt at the expo.  It runs like a well oiled machine.

NYC Marathon The Javits Center

The Javits Center

There is a booth for every few thousand bib numbers.  The athlete walks up to the booth that includes their bib number, shows ID and their registration card.  Then they receive their NYC Marathon bib and other instructions, verify their info and then walk towards the t-shirt area where on the way, they pick up a plastic swag bag that also serves as the gear bag for the race.  The official NYC Marathon t-shirt area is well-marked with a line for the different sizes and within a few minutes of walking into the expo, the athlete has bib, swag and t-shirt.

NYC Marathon The Expo

That isn’t the most exciting part of the  NYC Marathon expo.  There are vendors from all over the country whom give runners have the opportunity to try and buy the latest gear and gadgets.

One aspect of the expo I really enjoy, is the aura and feeling of the environment.  There is an excitement in the air of the larger expos that increases my heart rate a little and excites me to race.  It is probably one of my most favorite parts of any race weekend.

NYC Marathon Team Tampa PKD minus Karen

The following day we made another visit to the expo simply to walk around and make some purchases.  I found a couple of vendors that I had met at other races  and made some new contacts for product reviews.  Stay tuned.

I have loved New York City since the first moment I stepped into Manhattan years ago.  I have a lot of friends here, and I just really enjoy the pace and excitement of the city.

NYC Marathon NYC Times Square

There is always one place, that is mandatory to visit, at least once, every time I am in town.  John’s Pizza.  I couldn’t believe my ears, when Rich and Kevin decided not to partake.  It was their loss, so Scott and I headed over to John’s for lunch.  Carb loading, baby, I just love it.

I could write a full post on John’s, so I wont go into the heavenly scrumptiousness of their pizza here, but trust this self-proclaimed, pizza connoisseur, when I say the explosion of flavors that emanate from each bite, redefines the word delicious.

Saturday night, we were scheduled to have dinner with the PKD Foundation and the other runners from different areas at Carmine’s.  Scott, Kevin, Karen and I were all pretty familiar with the city and had even known of Carmine’s as it is pretty well-known.

That night we entered the subway and got off at 42nd street in order to head over to 44th where Carmine’s was located, as we started up the stairs from the station, Scott mentions the address which made Kevin and I do a double take.  2400 W Broadway, which was Broadway and 90th street.  At the moment we were on 44th st which means we were 46 blocks away.  That was a few miles from where we were at that point.

Of course like men we decided that maybe the address was wrong and went up anyway.  As it turns out, it was correct.  There was a newer Carmine’s uptown and we were in the wrong place and already fashionably late.

It ended up working out for us again.  We caught the subway up to 86th and when we arrived, food was just being served.  How long could this luck hold, right?

The dinner was fantastic and we met a bunch of really amazing people who were just as passionate about running for PKD as we were.

Like good little runners we went back to the hotel and retired for the night in anticipation for the NYC Marathon the next morning.

NYC Marathon The Night Before clothes layout

As I mentioned both in the last post and in my NYC Marathon recap from last year; the logistics for this race are not the most convenient.  It involves a ferry to Staten Island then a bus to security, a decent walk to the assigned village and finally another walk to the specific corral.

An announcement came out from the NYC Marathon staff, about two months prior to sign up for transportation to the start and of course we all missed and ended up getting assigned the 5:45am ferry to Staten Island.  Since three of us had already experienced the ferry and knew that there was no accountability, we decided to just take the 7am ferry instead, not only giving us a little more time in the morning, but also keeping us out of the chilly temps for a couple of hours.

The lesson I learned here was there are two choices, either go by the scheduled time and arrive with a lot of time to spare, sit around have some coffee and bagels while waiting for the start, or go a little later and hope to make it to the corral at the time of your scheduled start.

We took the latter ferry and ended up having to wait for two ferries to get over to the island and then when finally getting on the bus, the traffic was so heavy we ended up having to rush to the corrals in order to make the 9:40 start.  It was probably perfect for the rest of the team that had later starts, but for Rich and I it was a little tight.  Personally, I do prefer the latter.

NYC Marathon Statue of Liberty from Ferry

I found my green village, dropped off my gear bag with my long sleeve shirt and pants, and headed to the corral just prior to the 9am cut-off to enter the corral.  Now I had about half-an-hour to stretch and use the portlet one last time.

I was talking to a woman from Basel, England when I heard my name being called.  Ryan Wallace, was a Facebook friend and runner I met at last year’s race.  A really fun guy to hang with, so after chatting for a bit we found we were looking at accomplishing the goal of 3:50 or better.  Score!  Someone to run with.

NYC Marathon Start Corral

In the Start Corral

They opened up the corral to head closer to the start line around 9:30am, and just after the final note to one of the most beautiful renditions of our national anthem I have ever heard, sung by opera singer (and runner) Susanna Phillips Huntington, and announcements by the executive director, the gun went off and we were running.

The NYC Marathon is the largest marathon in the world.  Largest meaning the most athletes run the course of any marathon in the world..  This year there were over 50,000 finishers.  It boasts spectacular views, fantastic support from the spectators, and a challenging course.  The route takes the runners through all five major boroughs of the city, starting in Staten Island, crossing the Verrazano Bridge to Brooklyn, heading north into Queens crossing the 59th St bridge, then into Manhattan crossing the Queensboro Bridge, north into the Bronx over the Willis Ave Bridge, turning south back into Manhattan over the Madison Avenue bridge and then finally the incline to the finish line in the heart of Central Park.

The experience this year was better than last, as the temperatures were much better as we started around 55 degrees Fahrenheit  and just a little breeze versus the 30 degree temps and 33 mph winds from 2014.

Ryan, his friend, and I started the NYC Marathon conservative for the first couple of miles, but as we rounded the first 5k I noticed we started to increase our pace.  I only was witness to it due to calculating my 5k under 27 minutes, which being under a 9 minute mile that soon, concerned me a little, but I was feeling really strong.

The spectators in the NYC Marathon are everywhere and they clap, yell and scream not only for their family and friends, but for any one they seem to be inspired by.  Statistics pretty much show, that even know there were over 50,000 athletes running this race, and hundreds of thousands of finishers in marathons all over the world, less than 1% of the population has finished a marathon.  In other words there were a lot of people to be inspired by during this race and the spectators expressed that.

NYC Marathon brad behind ryan

The Goof peeking out behind Ryan

Ryan and I ran together up to about mile nine, constantly telling each other to slow down, yet neither of us could hold a slower pace for very long.  About that point, a pressure emanating from my bladder was increasing to a point where I was just not comfortable any longer, so I speeded up to the mile 10 aid station to relieve myself.  My thinking was speed up, use the facilitates and then speed back up just enough to catch Ryan again.

Unfortunately, we didn’t cross paths again during the race.  I was out there on my own, all by myself.  It was just me and 50,000 of my closest friends.

There was plenty to see as I continued on my NYC Marathon journey.  Achilles International volunteers were out in droves this year with guides helping blind and other challenged runners through the race.  Guides would run in a formation with one tethered to the blind runner and then three-to-four others running on each side of them constantly helping to clear a path through the crowd.   It was so motivating, that I knew somewhere down the line in my own journey I would have to help like that in some way in the future.

As I crossed the 13.1 mile marker of this NYC Marathon, and saw the clock I realized that I had been running for an hour and fifty minutes.  That for me was fast, but I was still feeling really strong.  The sights of the area’s architecture, parks, people and the smells of the local restaurants were consistently keeping my mind occupied as I just let my legs decide what they were going to do.

I was concerned though.  I know enough about myself, that keeping this pace would have it’s consequences toward the final miles.

My favorite bridge on NYC Marathon course is the Queensboro bridge.  It feels like it never ends, but the view of Manhattan and the Hudson is spectacular.  Not to mention, the completion of the bridge is a u-turn with a horde of spectators that it feels like a roar of excitement is exuded from them.  I felt a boost of energy when I crossed mile 16.

I was actually a little impressed with myself as I hadn’t really slowed as of yet.  It is usually around this mile marker that begins the stiffness of the previous miles.

The next checkpoint for me is usually mile 18, but that too came and went without any real pain.  My inner dialogue started having delusions of grandeur of possibly finishing the race around the 3:40 mark which be a huge PR for me.

As I crossed the Willis avenue bridge, I felt the start of a twinge in my left leg and a smile crept across my face and out loud I said to myself,”There it is.”

The NYC Marathon mile 20 clock showed I was two hours and fifty-two minutes into the race, which was already better than last year.  My thinking at that point was that I could pretty much slow to a ten minute mile at this point and still cross under four hours, but that didn’t happen.

Mile 21 came at just three hours which was a first in a while for me.  I am usually only at 20 by three hours and here I was a full mile closer to the finish.  My period of optimism was cut short by a stiffness in my right leg that quickly became painful.

NYC Marathon Starting to hurt

I walked though the next NYC Marathon aid station and grabbed a banana from the hand of a volunteer thinking just get some more glycogen to my legs so I finish this last five miles.

What little stride I had became periods of walking between miles 22 and 23 as the pain started to sear and engulf the rest of my leg.  It was getting harder and harder to bend my right knee as the stiffness was setting in.

Central Park came and the crowds were getting louder and more dense.  I did not want to walk through the park with all these people.  I wanted to run in strong, but the pain was getting more and more intense.  I actually yelled at myself, “C’mon legs.  WTF are you doing!!!”

NYC Marathon Almost There

My mind drifted to Erika at that moment.  As I was trying to run stiff-legged and just suffer through this intense pain, I thought that this frustration and uncomfortable feeling must be what Erika feels all the time.  The disappointment at feeling run down, the pain that comes with these huge cysts on her Kidneys and the eternal uncomfortable feeling that keeps her from sleep and just enjoying life, must be one hundred times worse that what I was feeling.

If Erika had to continually go through this pain, then I could at least endure it until I reach the finish line.

I didn’t stop running, no matter how much it hurt.  I thought about Erika and the last couple of years of misery she must have been going through, and how Jennifer would also have to also have a painful times ahead through her recovery from donating a kidney.  It kept me going as I really felt like I was going through it for them.

I am not a totally idiot, I know that running the NYC Marathon of which I enjoy doing, really would do nothing for either of them.  It was the fundraising and support where we as a team were doing the most good.  Maybe it was for me.  Maybe because I was not able to donate my kidney, that I the pain I was feeling now was so that I could empathize with both of them.

NYC Marathon The Finish

The NYC Marathon finish line was just as glorious as the other marathons I have completed.  I was extremely happy to cross in 3:56 and at least beat my time from last year by about 10 minutes.

My official NYC Marathon finisher was medal handed to me, I was congratulated by a volunteer and ushered through to take continue the long mile walk to retrieve my gear bag.  I was engulfed on all four sides with athletes as we all did the marathon shuffle through the park.  There was a sense of peace and a little giddiness that filled the air.

NYC Marathon Medal FInish

We all did something extraordinary today.  Whatever the reason “why”, we were bound at that moment by the accomplishment and conclusion of a journey that started with the decision to embark, the hours of training and the final step across the NYC Marathon Finish LIne.

NYC Marathon Stepping Across the finish

Once dressed in dry clothes, I found Rich and we headed out to The Keg Room which was where Team Tampa PKD would gather back together.  As Rich and I were in the first wave, where he PR’d at an incredible time of 3:27, we arrived first.  Kevin, whom was actually in the last wave to take off, showed up next followed closely by Karen and finally Scott.  Everyone finished and accomplished what they set out to do, but I was most proud of Scott.

NYC Marathon Keg Room

Scott had micro tears in his gastrocnemius muscle (Calf) and had been trying to rehab it for the last couple of weeks.  I really didn’t think he would finish the NYC Marathon and we all told him it would have been ok if he didn’t .  He did though and under 5 hours with walking.  He also said that he felt like he didn’t feel like he did anymore damage.

I am proud of the whole team.  Team Tampa PKD was able to raise over 20,000 for PKD, finish the NYC Marathon and, most importantly, find a kidney donor for Erika.

Goof Review: The Altra Impulse

Goof Review: The Altra Impulse

Altra Impulse

Are you seeing a pattern yet? Yes, I am becoming a huge fan of the 6 year-old running shoe company known as Altra.  As I have been instructing clients in form techniques, and have found that most of the models Altra manufactures, lend themselves to my favorite principles.

The Altra Impulse is no different.

What I like about the Altra Impulse

As with all of Altra’s models, my favorite advantage is their FootShape™ Toe Box.  This is the incomparable wide toe box that Altra is known for.  The toe box is makes any of Altra’s models recognizable from a good distance away.  That is how wide it is.  I enjoy the ability splay my toes and have my feet firmly hit the ground without them being cramped up.  Wider toe boxes also allow the feet to develop more strength because the shoe is not tightening around the ball of the foot or the toes.  The toes can move around, and tackle all kinds of terrain.

As you can see from the x-ray below, the amount of splay the toes are allowed in the Altra vs a traditional toe box.  Imagine having access to the full splay of your foot while you run.  What is amazing is that most runners do not even realize the limits that a traditional toe box causes.  (Hmm, maybe there is an idea for a full post.)

FootShaped™ Design

The Altra Impulse is no different in this department.  The FootShape™ toe box has been incorporated and has all the comforts of the other models I have run in.

I love the Zero Drop™ technology that Altra incorporates.  When I run I have the ability Altra Impulseto utilize the full power and flexibility of my calf not to mention I can run as if I was barefoot, as our bodies were intended.  Most traditional running shoes have a 12mm heel drop.  This means that the heel is 12mm above the ball of the foot.

When we are barefoot, the heel and the ball of the foot are equal which is a Zero Drop™.  This also helps with heel striking.  Have you ever tried to heel strike while running barefoot?  Even if you are a regular heel striker in shoes, it is almost impossible to heel strike while bare foot running.  A huge effort has to be made to do that.

So, why runners continue to heel strike?  If your heel is more cushioned in the shoe, then of course you will want to hit that area first. (Another post may be needed to explain a little more on this too…stay tuned.)Altra Impulse

 

I love the Innerflex™ which are grooves at the bottom that create a more flexible sole.

One of the huge differences with the Altra Impulse is that they also incorporated their patented StabiliPod™ technology along side the Innerflex™.  Now you have a stability shoe that is also somewhat flexible.

I have decided to put this feature as a liked feature more for others than myself.  As a pure neutral runner I prefer to work allowing my body to support me, not my shoe, but Altra is marketing this shoe not only for running and triathlon,  but for cross training as well.

The StabiliPod™ technology does really help in moving laterally, which is not something that is usual for runners, and especially those of us whom usually stick to the pavement.  This is why I do like this feature.

Altra ImpulseMy absolute favorite feature of this shoe are the drainage holes in the sole.  My very last test run with the impulse was an 8 mile run, immediately following a huge rain storm here in Tampa, Florida.

 

My route took me through numerous ankle deep puddles and while my socks remained damp, the shoe was clear of water within a few yards of the puddle.  There was no squish from the sole of the shoe or my sock because as my foot pushed down on the shoe, the holes squeezed water out the holes.  No more blisters from soaked uppers and water log socks release water as well.

The Altra Impulse also continues with Altra’s A-Bound™/EVA blend compound which sits directly under the foot and adds a return of energy and reduces ground impact.

The upper is a light material and does have a noticeable difference from the other models.  The tongue and laces are curved with the shape of the shoe which differs from the straight tongue of traditional running shoes.

Altra Impulse

I actually enjoyed this new feature.  The fit of the shoe felt more comfortable with the tongue falling in the same curve as my foot.

I rarely run without socks, but I did end up having to do go out for a couple of miles one day without socks, and they were extremely comfortable.  While the upper is not seamless it is very close.  There are only a couple of seems that surround the tongue, but they are covered with a light fabric that helps reduce any friction.

What I wasn’t so crazy about

This is probably a very individual issue, but even though I sized up to a 10 from a 9 and a-half, after a few miles my toes still ended up moving forward till I they hit the front of the shoe.  This probably has to do with the fact that I only lace my shoes tight enough to lock in my heel.

If you like your shoes laced up tight this probably will not be an issue.

The price point for the Altra Impulse is $120 dollars, which while competitive in the market place it still is a little expensive.  In this day and age where people are scrounging for liquidity, I really would like to see at least one company come out with a quality shoe that retails for under $80.  Of course that is my opinion and my opinion only.

How did the Altra Impulse Rate?

Quality – 4/5

Upper  – 5/5

Outsole – 5/5

Flexibility – 4/5

Comfort –5/5

Appearance – 4/5

Cost – 3/5

Overall – 4.2/5

Goof Review – Newton Energy & BOCO Running Shoes

Goof Review – Newton Energy & BOCO Running Shoes

Here it is again, a long time since my last post.  Life happens and when it does, watch out.  It can really mess up the things you want to do versus the things you must do.  I am learning to prioritize what is absolutely important to me versus what is important to everyone else.  I hope to soon have that under control, but I digress.

Newton was nice enough to send me both a pair of the Newton Energy and the BOCO.  I am reviewing them together since I have found they are the same shoe with the only difference being the BOCO has a tread that is made for the trails and the Energy is made for the road.

To be transparent and honest, I am a certified Newton Coach, so I am a little biased towards Newton.  However, I rarely train in Newtons, as running is very personal I have my favorite running shoes to train in.

I do however, love the methodology behind them.  For those that do not know, Newton running shoes have 5 lugs in the front of the shoe directly under the ball of the foot.  The lugs have a higher or lower profile depending on the shoe.

The lugs serve as a reminder for running form by automatically driving the foot to land on the fore or mid foot, reducing the impact dramatically.

When paired with Newton Natural Run training, the shoe will decrease the effort level of transitioning to a mid or forefoot runner.

In my experience, after the runner has developed the habit, they no longer need to be running in Newtons, but most do not only due to muscle memory, but they also last about 4 times longer than other running shoes.

Prior to the release of the Energy, the core products Newton produced were the Motion, the Isaac, the Gravity and the Distance.  These models needed a transition period for the runner to get used to the way the lugs lifted the heel causing some calf soreness.

The Energy now has a lower profile of lug, and a transition plate which actually allows the athlete very tiny transition period, if any, before the comfort of the shoe settles in.

The EVA foam that makes up the sole of the shoe is extremely comfortable and highly accommodating to the road.

The only conflicts I have heard is the heel cup is a little shallow for some, causing some slippage during long runs.

Since one of the core beliefs of natural runners is that shoes should be tied just tight enough to secure the heel, this could be a problem.  I have always taught, the athlete needs nothing to support but themselves.

In other words, if the shoe is tied too tight, the shoe ends up supporting the runner.  By tying the shoes very light and only tight enough to secure the heel, the feet, the calves, the ankles are strengthened with every activity.

I personally have not found an issue with the heel cup even without the help of a runner’s lace, but I have heard of the issues.

I did get an eleven-mile run on the trails with the Newton BOCO and was I surprised at how well the tread grabbed the terrain.  

The trails I was running were meant for Mountain Bikes and that meant steep climbs and steep downhills and there was not a moment I did not feel secure.ZOE_0005.jpg

For new runners or for athletes transitioning to more efficient technique, I believe the Energy is the perfect shoe.  They are the perfect shoe to transition with before trying one of the core Newton models.

The BOCO is a great trail shoe for anyone wishing to start or continuing a journey into trail running.  They are comfortable, supportive and made me feel completely secure on the trails.

That’s my opinion and I am sticking with it.  Happy Running!

How to Run Faster by Running Slower

How to Run Faster by Running Slower

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.image

 

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.

Uh…what?

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 Increase

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 creation

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.

optimal-easy-run-pace

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.

Carpe Vitam!
