To Run or Be a Runner in Triathlon

To succeed at the highest level in triathlon in the run off the bike, does one need to be a runner, or just run fit? Those of you that know what I do for a living can clearly see this is a loaded question. Can sufficient run conditioning work propel a triathlete who can move herself through space on foot at the prerequisite pace to success in a triathlon race without having the running skills to do so; i.e. while looking like a runner? I say no – a Chris Lieto obviously does not arrive at the world championships not “in shape” to run a marathon that is sufficient to defend his prodigious bike result & get the W; so what’s missing then? Clearly our love of the sport lies in looking for that elusive day when we put it all together & the “gamble” that this entails every time we lay it on the line is where the magic lies.


Lately I have been standing before a new paradigm; sure, address the specific limiters I see with each individual triathlete, but perhaps more importantly & effectively, in terms of my mission to see beautiful runners in triathlon that please even the pure running fans, establish a baseline level of running skills through tried & tested key drills introduced from the beginning of the triathlete’s career if they have not come along a running pathway. All runners can skip, do the karaoke drill, bound, & sprint – not all triathletes, even VERY good ones can!

The more triathletes I work with, especially the higher performing ones with amazing swim & bike abilities, the more I realize that they have developed from a young age in especially the swim, through the regular pathway of swim drills & development – growing up to be swimmers. They eat, sleep, drink & visualize swimming (or whatever their chosen sport was) & became that thing. While maintaining those skills & giving up on some of the volume & frequency that got them there, they need to have a minimum level of cycling & running skills. It would seem to me that a far better way to approach this situation, rather than try to fix what is broken about their run, is to have them learn & master the basic skills & see if their run does not naturally progress in this fashion. Then, when they have a basic skill set in place, work on the specific limiters they display.

Quantification Conundrum Part I

Bio-mechanists have incredible tools & wonderful training that tells us what our limbs are doing when we run. They also have pretty amazing tools to measure how much our muscles are working & when. The concept of “rebound” or elastic return is harder to measure – only a few labs can do this & the results are hard to nail down – an essential, but pretty new field of research. Add to this that the picture of running effectively mechanically has no real set of baseline data that represent perfect form – there are so many idiosyncrasies in top runners. Some, like Haile Gebrselassie have tried to effect changes to no avail, but have made changes to other things, like foot strike, in his case & have gone on to succeed admirably after these changes. Generally change introduces other variables & often a whole new set of problems. This is why wise coaches sometimes leave well alone. “Don’t fix it if it ain’t broke” holds especially true when it comes to running mechanics. Most individuals I see come for 2 reasons:


1. They are broke or

2. They’re stuck & cannot go faster

Both good reasons if all the other factors have been considered; things like over-training, incorrect training & insufficient training. Nowadays, with the elites, I am finding that they cannot run fast enough with their current form to access the type of training response that will take them to the next level.

IF YOUR CURRENT TOP END REPRESENTS ONLY A SMALL INCREASE IN SPEED FROM YOUR REQUIRED RACING SPEED, BE THAT FOR A 5KM OR A MARATHON, THEN THE LIKELIHOOD OF YOU MAINTAINING REQUIRED SPEED FOR THE DURATION BECOMES MORE & MORE CHALLENGING.

A car that has been designed to drive along at 100mph is likely to be much less stressed at 65mph than a car that can only manage 70mph.

If one accepts that we have a fixed rate of slowing with each doubling of distance, & I do believe this, then ultimately you have a finite speed at which you can run your preferred distance run, no matter how much fitter you get.

9. Correct arm usage for runners

The arms are closer to the brain than the legs. Your arms are “cleverer” than your legs as a result. Fatigued limbs have a hard time responding to cognitive commands, making “access” easier through reflex, rhythm pathways. Part of this also occurs when synapses are used repeatedly – they start to lose choline & struggle to relay messages. These facts make it possible through the intricately integrated connection between all limbs, called the kinetic chain, to use your arms effectively to run better. One key component of effective running is to have your feet be on the ground for the briefest period possible for any given foot strike. This is called stride rate & if the arms & legs MUST move in unison (left knee to right elbow in front for example), it stands to reason that the quicker the arm is punched rearward & then automatically swung forward on the opposite side, the quicker the legs must move – effective running is often measured by how rapidly the foot can return for the next foot fall from toe off. (Of course stride length is the other half of the equation, but that’s another matter all together.)


Ensure that the arms remain bent at the elbow at 90* or even more closed; I often use a little pebble, held in the crook of the elbow & not to be dropped while running, to drill this component. The lowest part of the arm, at any point during the swing must be the elbow; the shorter the lever the quicker it can be swung. If there are no deficiencies elsewhere, the arms should be swung symmetrically under the shoulder – i.e. when the thighs are parallel during the running gait, the forearms should be parallel with each other & the surface & the middle of the forearm should be directly underneath the armpit/shoulder. Keep the hand above the short line. When viewed from the front the hand should be inside (or nearer the body than the elbow). If possible keep each arm on the outside of the sternum & try not to cross the center line. Some good runners do however do this & it is not a deal-breaker. What is a deal-breaker though is rotating the upper body across the line of travel where clearly there is a “disconnect” between the torso & the legs.

Good runners even close the elbow angle when the arm is swung to the front & open it somewhat when swung to the rear. Keep the hands loose & the wrists firm, with the thumb on the forefinger as a general rule of, um, thumb!

Relaxed, bent, coordinated, quick, rearward punching arms will help you be a more effective runner.

6. Are you a lifter or a pusher?


The answer could be the silver bullet your running needs

Last time we spoke about the forward lean & its contribution to an increased stride rate – a highly desirable component required to being an efficient runner. That forward lean is one component that increases stride rate; power application is the other. However an increased angle of attack does not guarantee increased stride rate in some cases, as habituated lifting of the knee, in an effort to increase/maintain stride length continues to access majority concentric muscle contraction of the hip flexors. This not only slows stride rate, but greatly increases the strength requirement & therefore an accelerated accumulation of fatigue from dealing with eccentric jarring from increased support phase weight bearing time. It also creates more fatigue because the stride falls more towards the forward sector relative to the center of mass, & thus increasing work to regain this lost inertia with each step. It is a common myth that in order to have that nice high knee lift when you run you have to fire your hip flexors – nothing could be further from the truth. By powerfully extending your leg downwards it subsequently is dragged rearward (because of forward momentum & the foot striking a stationary surface). The leg is not driven in an effort to push the body while it is on the surface – this would be counterproductive as tissue is supposed to be held semi rigid as connective tissue stretches/loads in anticipation for elastic release upon toe off. It is essential that the driving phase is seen as unloaded & with gravity. In this way the hip flexors are extended/loaded & pop back powerfully because of this, leading to that light, springy high knee lift so characteristic of great runners. Again, please make sure that you do not push while the foot is on the ground, but before this; it’s like throwing a pogo stick at the ground. If you push while the foot is on the surface you stop it from unloading elastically. Good running is 5 parts elastic return & only one part strength application – the more you lift your knees & try to power your body by driving the foot while it is on the ground, the greater the strength component, the slower the stride rate, the longer the stance time, the greater the rate of fatigue accumulation. Nuf said!

5. Lean your way to great running


A slight forward lean from the ankles, with the chest & pelvis squarely aligned is a great way to gain a mechanical advantage by utilizing gravity. A forward lean also increases cadence or stride rate, which is an extremely desirable asset to the distance runner. Please note the word slight – leaning too much can create over rotation & put pressure on the core muscles & increase loading in the hamstrings & hip flexors. Do NOT lean from the waist, this is a recipe for disaster. Keep the elbows bent 90* or less – the hallmark of all great distance runners is that bent elbow. Take smaller, but quicker steps & run lightly over the running surface. However do not chop your natural stride length down – allow the speed to determine stride length. The faster you run, the more you can lean. You are trying to reduce surface interaction time, but do not want to have to either lift the foot off the ground or get to the surface too soon & increase friction. If you are leaning too much, your foot strike becomes too loud & therefore heavy & you will have to lift your legs to clear the foot to stop it from scraping the surface – this lifting is a total no-no!

Get Connected


If you don’t contra rotate your torso when you run, you are disconnected & if you are disconnected your Center of Mass & your strength (concentric) component is high – therefore you are inefficient; so learn how to contra-rotate, but don’t do so cognitively!
Huh?
Yeah I felt the same way when 1st I started to figure this one out.
The world of Feldenkrais is an esoteric one to say the least & it draws the more “abstruse” of us to it & thus work from this field is often pooh-poohed. But of late there is some great stuff coming from certain members of this community who teach running – they really get “being connected” when you move. Check it out.
In swim/bike/run, all are equally dependant on good solid coordinated connectedness – try climbing on the bike & not pulling with the opposite arm! Or try swimming with only lats & pecs & not core – some of us can do this (yeah me!) & hoo boy, do we swim poorly!
Trouble is, in the run, if we were not connected from the start, or we fiddled around with some “technique” suggestions from a 2-dimensional model of bio-mechanical quackery, the unlearn (of the disconnected) & the relearning (through cognitive pathways) is a tough one.
The steps are:
1. Recognition – have an expert take a look
2. Correction – 1st through understanding & seeing (video), & then through presets & drills
3. Habituation – constant repetition till cognitive gives way to automatic
4. Confirmation - in races & hard training, especially when fatigued; should feel smoother & easier & be able to go longer & faster!
For more, check out my DVD, Triathlon, The Run, with explanations (understanding) & drills (learning)
Yours in connectedness!

4. Stride rate is the key to successful running


The forward lean in running is free speed, but the high stride rate, turnover or cadence really is the most important aspect of successful running. The less the amount of time, per foot strike, your foot can be on the ground, the less strength is required, the less fatigue is accumulated & the less eccentric micro tearing in the leg muscles takes place. A hallmark of champion distance runners is a stride rate of over 180 steps per minute – some as high as 208! Count your cadence by counting the number of foot strikes you achieve with one foot in 15sec & then multiply that by 4. This will give you a single leg turnover. The minimum number you are striving for is 23 (or 92 steps per foot per minute, which is 184 for both feet). Your length, leg length or gender is irrelevant. Lastly, do not simply try to move up your cadence by moving your legs faster; this may lead to injury & may not improve performance. Do this by leaning slightly forward from the ankle, staying tall through the hips, bending your elbows 90*, (till you could hold a pebble in the crook of your elbow & not drop it for the duration of the run), punching your elbows rearward slightly &, most importantly, pushing your foot to the ground, (but NOT while on the ground). Do this rather than launching up into the air (pushing off) & dropping to the ground – a recipe for injury, fatigue & poor performance.

Of books & audio visual. Finally the Biomechanics DVD!!!!!!!!!!!!!


It's here after fits & starts - my running biomechanics & drills DVD. Triathlon, The Run - Comprehensive Running Biomechanics & Drills. It is available through my website http://www.bobbymcgee.com/ or http://www.endurancefilms.com/.

It's strange, all 3 books that I have written were sourced differently in terms of their initiation. Magical Running was written because I'd come to a point as a coach where I realized that the immense efforts thrown at coaching individuals, especially at the highest level, were never going to be rewarded with commensurate results. By "coaching" I mean working the physical details, designing workouts, refining training, blood work, nutrition, equipment, routes, altitude, training theory & application... All this so often amounted to nought on the day of the really big competitions because of what was going on mentally & emotionally for the athlete - here there was no distinction between normal human being & athletic super being; the normal human frailties ruled & the performance most often showed it. So often the physically "inferior" athlete won the day. But they were mentally WAY superior & I knew both through formal training & instinctively that winners can be made mentally as well. It took me years to fully grasp the subtle performance differences between the mental & the emotional. Through extremely empowering personal work that I did & within the context of my formal sport psychology training, I came up with a mental skills training model that formed the basis for Magical Running. It has subsequently been proven to a be rather successful guide for those that take on the often confronting task of self-discovery & the replacement of mindsets that hold them back from the performances their bodies are capable of.

Then came Running Sports Essentials, now sold out of its 1st edition. Again a booklet that was not directly about run training - born of a realization: when we begin running, we do not start from zero, but years of plain old living has left us at minus something in most departments. Run training alone will lead us to injury & at least to a plateau. The framework upon which we build the running needed to be Kenyanized; brought to a place where it could properly absorb training in order for performance & not breakdown, to result.

Of course when it comes to muscle activation, dynamic warm up activities, stability training & effective post training activities there is so much new research coming to the fore that I decided that Running Sports Essentials needed to grow into Running Sports Essentials Plus. And don't you know it, there is much that needs to happen before what's been percolating in my mind after countless consultations with experts, & final fruition in the form of a publication. So to those of you who are asking for Running Sports Essentials & those of you who have benefited from using it, please be patient, I will get to it!

Then came Run Workouts for Runners & Triathletes. This time I was offered an opportunity to do what I have always wanted to do, but was too busy doing it practically, to write it all down in one cohesive piece for others to apply & use. Again there was the fear of rejection & self-doubt in the light of the great books & great successes of great coaches that were already out there; but you know how it goes, nothing ventured nothing gained. At least I knew the principles had produced Olympic Gold, world records, world champions & Olympians, so it couldn't be all bad right? Writing it was a slog, I will not tell a lie, but when the 1st emails started to arrive of PRs & invigorated running, triathlon & walking success stories I felt the effort was justified - not that being published is not one of the neatest feelings out there. Yes, you read correctly, walking. Years ago I coached a multiple world champion & world record holding masters race walker, by name of Barbara Nell. She still races & now also coaches & by using Run Workouts for Runners & Triathletes, she has produced some astounding age group/masters walkers - like a 26:20 5km for a female masters athlete, or a sub 47min 10km for male masters walker. I get so many emails to the website (http://www.bobbymcgee.com/) of athletes successes on a weekly basis - thank you!

Now finally the running biomechanics DVD, Triathlon, The Run - Comprehensive Running Biomechanics & Drills. The last 8 years or so have brought the need for me to assist the countless great US swimmers that come to the sport of triathlon without a running background. Of course coming from South Africa, with a background in working with African runners who run BEAUTIFULLY because of how they grew up, it is kind of ironic! Now I have come to use my background in formal biomechanics training & the zillion hours of watching running done both well & poorly to assist in teaching individuals to do something that they would have learned naturally if they had lived miles from school on dirt roads, had no shoes & no transport other than their feet. I see athletes almost daily to help with their mechanics. I formally teach running biomechanics at least once per month & always the request was the same - "Can we have a DVD of this, how are we going to remember how to do this, how can I teach this, how am I going to learn this from what I have written down?"

To improve your fitness takes weeks at best, but some mechanical interventions can improve your running instantly. Learn how & why you run as you do, assess whether your mechanics are holding you back & do the drills - you will run easier & faster.

Well now you have it - my approach. Of course, now, a year on from shooting (last April), I wish I could have added another 30 minutes with the new stuff I have learned. So next time you see me, ask me about launch angles & set up & I'll gladly comply!

Although the focus is on triathletes, the running mechanics principles hold true for all endurance running - in fact for the average runner it is easier to relate to triathletes than elite runners as they are slightly larger & have certain running challenges because of the swim & the bike, making them more "normal" than the sub 120lb males & sub 100lb female runners we see blowing around the marathon courses & tracks of the world like nothing more than feathers upon the wind!

So visit with me on the website & see if we have something than will help you run just that smidgen faster/better.

Think fast, look fast, do fast, be fast
