Back in June, I watched online as Faith Kipyegon unsuccessfully tried becoming the worldâs first sub-4 miler woman. The event was one of those multi-million-dollar circus shows put on by Nike to test human physical limitations. It was elaborate enough that, just like Eliud Kipchogeâs Sub-2 in 2019, it would not have counted as a world record should she succeed.
Athletics and the principle of diminishing returns (Image by ChatGPT)
Kipchoge needed to improve his marathon time by 100 seconds, and he did, finishing 19 seconds ahead of his previous record. Kipyegon needed to shave about 8 seconds (7.65) to achieve her goal, but she ended up about 6.5 seconds short. Even with the circus, space technology, support, and male pacing, she couldnât do it.
The failed attempt got me thinking about a basic concept in economics that easily applies to running: the principle of diminishing returns. In economics, this means that ff you improve one variable while keeping all the others constant, the incremental output gained from each extra unit will eventually fall. In other words, building a skyscraper in one day wonât be solved with more workers.
The same principle applies in athletics. Dr. George Sheehan, one of the greatest running writers, put it this way: âThe first mile is the most helpful one as far as conditioning goes. Each succeeding one gives less and less benefit than the one before. Runners who work more and more are working for less and less. [âŠ] It doesnât take much to get 90% fitness, only a few miles a day. But it takes progressively more and more training as you get closer to your ultimate potential. At the highest levels, you are putting in a huge investment for a very small return. It is the small gains what makes the difference between winning and losing.â
Think about it, itâs obvious. If not, it would be a matter of time and more miles before we all became elite athletes and broke world records. We all have a limit, and while reaching it is feasible, it requires a tremendous amount of work.
I recently heard Coach Steve Magness share a story where Shalane Flanagan told him something along the lines of, âThe difference between being in 2:30 marathon shape and 2:20 is astronomical.â For you and me, average, mid-to-back-of-the-pack marathoners, a 10-minute improvement may be a diligent training cycle away. For elites in a Marathon Major, this same result guarantees them peeing in a cup to verify cheating.
Nice background, Coach! But how does this apply to me, the average weekend warrior?
It is about training smarter, not harder (Image by ChatGPT)
I am glad you asked! The point of this introduction is for the reader to understand that the curve of progress in running flattens as we improve. It is a reality we canât solve with harder training. Progress is not a linear proposition.
And, while achieving the last 10% requires an astronomical effort, it is feasible. It is about figuring out what works for you. Just because Jacob Ingebrigtsen uses the Norwegian double threshold method doesnât mean it is the solution youâve been looking for. He is in such shape that this is the only type of training that will extract the extra hundredths of a second needed to break a world record. This training may land you, my dear average-runner reader, on the injury list.
Working around the principle of diminishing returns to reach your apex requires smarter training. Not just harder. As gains slow, finding that sweet spot between effort and recovery is the magic sauce. It may mean varying your workouts, adjusting intensity levels, or prioritizing recovery and nutrition more seriously. As we improve, we must tune into our bodyâs signals, such as fatigue, soreness, or lack of motivation. These can guide adjustments before you hit a training (or overtraining) wall. If in doubt, a training plan tailored exclusively for you may help you progress without burning out.
In conclusion, In athletics, more is not necessarily better. Most of what elite runners do to squeeze that last sliver of greatness out of their performance does not apply to you. We are all limitless, sure, but not in all areas of our human performance, athletics being one of them. Letâs work hard to reach our goals, but not at the expense of burning out.
What are your thoughts on this principle? I will read and answer your comments.
As long-distance runners, we focus on the long-distance run. Obvious. For marathoners, that 20-miler has been a staple our training for decades. The psychological advantage of having achieved that distance starting with a 2 instead of a 1, when you are about to run 26.2, cannot be overstated.
The benefit of that 20-mile run lies in the time it will take you to complete it (Image by ChatGPT)
Yet, there is no magic to be gained at 20 miles. If you train in kilometers, 20 miles is 32.18 Km, far from a round or memorable number. The âmagic markerâ for those who train in kilometers is 30, for the same psychological reason. This is equivalent to 18.64 miles. Nothing special to that figure either.
But, is there a physiological benefit from running a 20-miler or 30 kilometers, or two or three of them before your marathon? Does it apply to all marathoners? What does science say about this? How does all this apply to you and your training for your next marathon?
Letâs get into it.
While the confidence boost of having a 20 or 22 mile run under your soles is undeniable, its benefits are proven to diminish the longer you are on your feet. The elite Kenyans can cover the distance between less than two hours. The 3-hour runner can do it in 2:30-ish at an easier pace. But the 4-hour marathoner may take 3:45 at an easy pace. You can see the progression.
According to scientific studies: âafter running 3 hours the aerobic benefits (capillary building, mitochondrial development) arenât markedly better than when you run two hours.â This means that a 3-hour run will provide as much aerobic benefit as a 2-hour run. So you will accumulate additional fatigue and need a longer recovery before resuming your normal training.
Iâve read about coaches that do not prescribe 20-mile runs for anyone looking to run over 3:45 in the marathon. Others say 3:30 or even less. Remember that coaching is the intersection between art and science. An art based on science, not a science per se, so trial and error are part of the deal.
In my professional experience, runners that will run their marathons on the slower side than 3:30ish, will benefit from back-to-back runs that will allow accumulated fatigue to do its thing without breaking down the body too much. A long run today followed by a âlongishâ run tomorrow, where you accumulate from 18-22 miles in a weekend, produces better results than plowing through that mileage in one push.

This is not to say that for certain runners, at a certain level of fitness, with a certain goals and with enough time to recover, may not benefit from a 20-miler. And I am not discounting the psychological benefit either. What I am stating is that the 20+ miler is not the key to achieve your marathon goals if you are not on the faster side.
Coach Jeff Gaudette, from Runnersâ Connect, wrote recently that one of the two primary reasons why runners get injured is âorogressing their training volume and running speeds at a pace that their body is not ready to handle. Or, as coach Jay Johnson would technically define it, âmetabolic fitness precedes structural readinessââ.
Before you ask, the other reason is structural imbalances and/or bio-mechanical issues.
Coach John Davis, a PhD in biomechanics at Indiana Universityâs School of Public Health, provides the following recommendations when it comes to the long run in a marathon training cycle.
Donât overemphasize the long run, especially when training for the marathon. Not only do aerobic benefits flat line after 2 hours of running, but as this research shows, injury risk increases significantly.
Think prehab rather than rehab. Work on strengthening known or potential weak areas in your running mechanics.
Fix flaws in your running form that become exacerbated during long runs. Improving posture, learning to generate proper hip extension, and fixing overstriding can help prevent many potential injury issues.
In conclusion:
The long run continues to be an essential element of the marathon training. Thereâs no way around it. But contrary to what has been drilled to us for so many years, the qualifying aspect of the long run is time, not necessarily mileage. It is not the longer the merrier. It is the longer you can run without hindering your recovery, the merrier.

Before I answer the question in the title, I want to answer something else: Is this a self-serving post? Yes. It is. I am a running coach. You are looking for one and have questions about how this works and whether it’s a good fit for you. I am here to provide you with answers. So, here we go.
If you Google ârunning coach,â as I just did, you will get over 300 million results. If you Google âmarathon training plans,â the number is severely reduced to just 150 million. How are you supposed to sort through that? How will you find the right plan or coach that is a good fit for you?
A runner I coach told me once that a buddy of his stated that a running coach was a waste of money because you can download a free marathon plan from the internet. My client responded by saying: âIt is more complicated than that. You need to know what you’re doing, and you must read about 40 books. My coach has the experience and has read them all. I donât have time for that.â
According to a data study by RunnersConnect, runners with custom plans ran 10% faster. They were injured 36% less than those using basic, generic plans. If that wasnât enough, they also achieved their goal 54% of the time, compared to 29% with stock programs.
It is essential to know that unless you live in your coachâs city or are part of their running groups, you will see very little of your coach in person, and you may never meet them. This is normal. The only coaches present at every one of their athletesâ sessions are either high school or college coaches or elite coaches. If you are searching for an online coach, most likely you donât fit that description and your goals are different.
So, what are the advantages of hiring Foultips.Run as your running coach:
âș Experience and Knowledge: Iâm the head coach at Foultips.run with over 40 years of running under my belt. I hold an RRCA Level II certification, have completed over 150 races ranging from 5Ks to marathons, and I stay current on the latest scientific and physiological insights in the sport. To learn more about my background, click here. The coaches I work with are handpicked; each one personally vetted and backed by proven expertise.
âș Individualized Plans: Downloadable programs are dime a dozen. Some free, some paid. Those programs, you must understand, are generic and do not consider neither your starting point nor your specific running goals. They apply equally to the Olympic swimmer transitioning to marathon training to the overweight middle-aged want-to-be runner just getting off the couch after 15 years. Additionally, they are not flexible and usually lack cross-training. Additionally, you wonât have access to the person who wrote it should a personalized adjustment be needed.
âș Access to your coach: I cannot speak for other coaches, but with Foultips.run, your coach is a phone call or text message away. We pride ourselves on not just telling the runner what to do but educating them on why we recommend a specific workout or an extra day off. Access to your coach is the primary reason you chose an online coach over a downloadable static program.
âș Tech platform: Foultips.run works with the FinalSurge software, which is included in the athleteâs monthly fee. This platform syncs with multiple fitness watches, allowing the coach to provide feedback based on all the performance parameters your watch records. This makes adjustments to optimize progress a common occurrence.
âș Guidance: An athlete wishing to run needs a different level of guidance than an experienced runner pursuing another PR or returning after a hiatus. Your running coach has the necessary experience to understand the different stages of your journey, so you can be guided accordingly with the correct feedback and resources to navigate your process.
âș Flexibility & Customization: You are not a professional athlete, and life will eventually get in the way. Maintaining a life/run balance is paramount, so sometimes runs need to be adjusted or shuffled. Sometimes it all needs to be scrapped and go back to the start
âș Motivation, not cheerleading: While keeping the athletes motivated is vital, especially during the inevitable downturns of a running cycle, your running coach is not a cheerleader. They will guide you through thick and thin but will not sugarcoat it if you have screwed up. It is never a failure if you get a valuable lesson from it.

It took me a while to understand it, but with maturity, I finally did. Training consists of two separate and different elements: Work and recovery. They are equally important, and they complement each other. Their symbiosis confirms the Aristotelian saying that the whole is more than the sum of the parts.
Recently, I heard that the second element is labeled as The Invisible Training.
It got me thinking about a classic Emil Zatopek quote where he states: âWhat you do when the stadium is full is important, but what you do when the stadium is empty is a thousand times more important.â
For us amateur weekend warriors, a standing ovation at an Olympic stadium is no more than a pleasant dream. Yet, well into the XXI Century, each one of us has the equivalent of our own Olympic stadium, and we have become addicted to that standing ovation of kudos Strava, followers on Facebook, and likes on Instagram. These may be cool for many, but they wonât get you any better.
As Zatopek (a 4-time Olympic gold medalist and multi-world record breaker) said, that is not the key to success. It is what we do outside the limelight that counts. A thousand times more.
âș It is the strength training that will help you get stronger, more resilient, have a better form, and make you injury resistant.
âș it is the physical therapy you do to take care of your bones, muscles, and soft tissues. Not just face-to-face with a professional, but as a prehab to avoid a recurring injury.
âș It is your daily nutrition that allows your body enough of the good stuff to repair itself and be appropriately fueled for your activity.
âș It is the hydration throughout the day that will allow you to sustain a hard run even in the harshest of weather conditions.
âș It is the scheduled recovery for your body to adapt to the stress we have put it through and accepting that sometimes it will require more time.
âș It is understanding that sleep is the champion of recovery tools in your arsenal and that lack of sleep is not a badge of honor.
âș It is accumulating knowledge about the sport and the function of your body, which will allow you to understand whatâs happening and why.
âș It is the evaluation of your training, especially when you have bonked or screwed up, and accepting it as an opportunity to learn and build experience.
âș It is living a balanced life, one where your job, your family, and your friends wonât be neglected, and end up resenting you and your running.
âș It is allowing yourself to have fun outside your running life. Keeping it all in perspective and always remembering why you are doing this.
These are just ten of hundreds of parameters of what is encompassed within the realm of invisible training.
In summary, everything you do while you are not running is equally essential to the running time.
Yes, it all sounds intuitive, simple, even obvious. But weâve all fallen into the trap of only accepting hard work as worthwhile training. And to many, an injury has taught us how wrong we were. My wish is that this brief writing will help avoid the injury part for you, dear reader.
Share your thoughts in the box below so other runners may benefit from your experience.
In the last post, we discussed the importance of building a strong aerobic base, one on which everything else can solidly rest. That post sparked valuable feedback. Many readers asked, “So, what comes after the boring stuff?”
Now that the foundation is in place, we build on it to get stronger and faster. Opposed to “the boring stuff” is what we Iâve heard called as “The Sexy Stuff”.
Speed over long periods/distances cannot stand alone. Adding speed work doesn’t mean abandoning the easy miles. It means balancing them with strategic sessions designed to improve strength, efficiency, pacing, and recovery.
Speed work isn’t a shortcut; it’s a complement. When done correctly and in harmony with your base mileage, it helps you become the strongest, smartest, and most resilient version of your running self.
Now that we have a base, it is time to work on speed (Image by CoPilot)
There are many types of speed workouts, each one with its own merits to help you run faster, with purpose, and without risking injury. The key is understanding that speed development isn’t about hammering every run to exhaustion. It’s about running with intention. Your easy runs remain the backbone of your training. But now, we are layering specific efforts designed for growth. To get faster, you need to run faster, but only when the time is right.
Examples of “sexy stuff” are the following:
1. Interval Training – Alternate fast running with recovery periods. They challenge your body to hold higher intensities and then bounce back. An example is short bursts of 200 or 400 meters at strong effort, followed by slow jogging. It’s tough but builds both strength and endurance quickly.
2. Fartlek – Fartlek means mixing in bursts of speed during a steady run. There’s no set structure. Just pick a landmark and push the pace, then ease up. It’s a fun, flexible way to teach your body how to change gears mid-run.
3. Tempo Runs – This is your chance to run at a challenging, steady pace that builds endurance and raises your limits. You should feel strong but unable to talk easily. These runs help you sustain faster efforts over longer distances without crashing.
4. Progressions – They are all about finishing fast. Start your run at a relaxed pace, then pick it up gradually. The goal is to finish the last stretch of the run feeling strong and in control, without gasping for air.
5. Hill Running – Short hill sprints build explosive power in your legs, improve form, and speed up your heart rate. They’re good for runners who want to boost their cadence and efficiency. Hills are strength work in disguise.
Other workouts such as Vo2Max, lactate threshold, double threshold etc., require a deeper knowledge of the science and physiology behind them before being tackled. Focus on what you know and understand, not on what the elite Kenyans are doing.
Cross-training is key to remaining healthy while running, especially as you age (Photo Pexels)
But that’s not all there is. To get faster and remain injury-free, you must do work beyond running. Some examples are:
6. Strength Training – Incorporating 2â3 strength sessions per week will make you stronger and, thus, faster. Full-body and compound movements will help with running economy and injury prevention. Think of squats, lunges, deadlifts, and core work.
7. Cross-training â Non-running activities like cycling, swimming, or yoga improve fitness, build strength, and reduce injury risk by working different muscles without the repetitiveness of movement and pounding of running.
8. Plyometrics – These exercises involve jumping and explosive movement to help improve your power and coordination. A few well-timed sets of bounding, hops, or box jumps before your run can sharpen your stride and reduce contact time with the ground.
9. Prioritizing Recovery –Your body needs time to adapt. Without quality recovery, your speed won’t stick, and you’re more likely to burn out or get injured. Sleep well, eat right, foam roll, and stretch as necessary. Gains don’t happen during training, they happen during recovery, where your body adapts and grows stronger.
10. Mental Strategies – Running fast requires mental fortitude. Breaking a tough run into small segments, repeating a mantra, visualizing success or adjusting your thought process may be just as important as the way you train.
Speed work is the exciting part of training, but it only works when done right and is well supported by your solid base. Both elements must work in harmony, complementing each other rather than competing between them. As you start integrating faster sessions into your week, keep your easy runs sacred, your recovery intentional, and your mindset focused on progress, not perfection. When done right, it is this balance what will make you a faster, stronger, and more injury-resistant runner.
Talking about our great workouts and spectacular results is a favorite topic of runners’ conversation. “Johnny’s mile repeats are spot on for a 5K PR!”, “Jimmy is crushing his track workouts.”, “Helen swears by her Fartlek sessions.” So, why am I not doing any of this stuff? Why does my coach have me doing boring stuff?
If you are training for long-distance running, your base is the key. The aerobic base, that is. A skyscraper stands on a solid footing for the same reason the pyramids have stood on their wide bases for 4500 years. They both have a solid foundation to bear the load. The same principle applies to a long-distance runner. Your aerobic base is the foundation of your running. It’s what every training block builds upon, and what ultimately supports your ability to perform. What good comes from running 400 meters in 62 seconds if that is all you can hold, but you are racing a 5K?
To understand the importance of an aerobic base for a long-distance runner, know that even the fittest and fastest Kenyan elite runner runs a marathon 99% aerobically. Even Olympic 5000-meter champions require about a 90% aerobic effort to compete at that level. You’ll likely never be there, but this doesn’t preclude you from the reality of human physiology.
In his “Guide to Coaching”, Coach Steve Magness states: “We have a temptation to want to skip to the ‘cool, sexy’ stuff. It’s boring to do endless easy runs or to spend hours working on the starting position in the sprints. But the ‘boring’ work serves as our foundation. We need a firm understanding of the basics before we move on to the next step. And once we have moved on, we must continually go back to the basics to ensure that they are ingrained.”
Is this clear enough?
The Boring Stuff
It is counterintuitive to accept that you must run slow so you can run fast. Yet this is one of those things you must accept, trust the science, and move forward with if you aspire to become a successful long-distance runner.
The slow (boring) stuff is the key to becoming a strong runner (ChatGPT Image)
Training at slower paces is the foundation of endurance because, among other things, it enhances mitochondrial density (improving oxygen delivery to the muscles), enhances capillary development, and increases fat utilization as fuel, which will make you a more efficient athlete. Low-intensity training also stimulates aerobic enzymes without overstressing the body, allowing more consistent training and better recovery. Over time, these physiological improvements will enable you to maintain faster paces with less effort.
Structured properly within your training, slow runs support speed, stamina and contribute to a better race-day performance. And this takes time. It doesn’t happen by running slow for a week or a month. If you trust the process and keep a written record of your workouts, before you know it, you will be running longer, easier and faster with the same effort. What once was your pushing pace, will now be your warmup pace.
The Sexy Stuff
Now that you have a strong base, we build on it.
Do you want to enjoy the runner’s highs? Build a base (Photo Pexels)
I often compare runners with F1 engines. They can do amazing things, but they require a lot of work, constant modifications and adjustments. The engine is the base, which is solid, but it can’t perform at the expected level without testing, tweaking and failures.
Short intervals, long intervals, Fartlek, mile-repeats, track, threshold, VO2Max, progressions, and so many more are part of the arsenal of workouts you have at your disposal to become a faster runner. These workouts will leave you pleasantly exhausted, provide you with that exhilarating feeling we have learned to love, and get you to enjoy the sweets of a runner’s high.
But be warned. These should be just a fraction of your workouts. You shouldn’t do them day after day after day just because you built a solid base. Maintaining and solidifying the base is a lifetime pursuit. The base of the Eiffel Tower has been constantly maintained since 1889, and thus, still stands strong.
Speed work is essential to becoming a faster runner, but easy recovery runs in between hard workouts and the ubiquitous long run should not be skipped. It should all be in balance.
So, next time your coach asks you to slow down, be patient, or play the long game, understand he/she is not doing so because he/she is mean. There are proven scientific and physiological reasons behind it. So, embrace the boring stuff and become a better, faster runner.
