Back in June, I watched online as Faith Kipyegon unsuccessfully tried becoming the world’s 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 Kipchoge’s 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 couldn’t 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 won’t be solved with more workers.
The same principle applies in athletics. Dr. George Sheehan, one of the greatest running writers, put it this way: “The 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. […] It doesn’t 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.”
Think about it, it’s 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, “The difference between being in 2:30 marathon shape and 2:20 is astronomical.” 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 can’t 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 doesn’t mean it is the solution you’ve 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 body’s 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. Let’s 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.
Back in April 2021, I published a guest blog post titled “Running With Lymphoma”, written by Annamarie McCormickHowell. The content is self-explanatory. Ten days ago, I received an email from Jen M, a runner with lymphoma who found the post and asked if I could put her in contact with the author. This made me wonder about Annamarie’s journey since then, so I invited her for an update.
Thank you again for the opportunity! Jen told me how long and hard she searched to find a person, a study, any data on people who run through lymphoma or R-CHOP, and the article you published is the only tangible thing she was able to find. I had no idea there wasn’t a larger body of humans doing precisely what I did, so I appreciate you connecting us!!
Life looks different than it did back on the day of my Chemotherapy Half Marathon, though some things remain the same, primarily, the daily morning run.
After cancer, nothing returns to normal, though I did notice a few weeks after R-CHOP, I had the sensation that I imagine to be akin to blood doping—having the appropriate number of white and red blood cells again made me feel unstoppable, as the chemo drugs slowly exited my system. I was able to run more, sustain paces, and even dabble in a few local races! After a few months, the novelty wore off a bit when I plateaued. I felt disappointment, followed by immediate guilt: I was alive, and my cancer wasn’t. How could I possibly be dissatisfied with something as trivial as running when I had managed to survive such an experience?
Winning the women’s race and 2nd overall at the 18.12 Challenge earlier this summer!
It was then that the universe gave me the greatest gift: a coach who saw not who I was in that moment, but who I could be. The indomitable April approached my training with expertise, confidence, and solidarity. Her lack of doubt in my abilities and body made up for ALL the doubt I was feeling. She literally ran into my life and began to push me in the most loving, challenging, unforeseen ways.
We started focusing on macronutrients, as I had lost a good amount of muscle mass to the chemo, and started training for short distances— specifically the 5K, with repeats like I had never performed before in my life. A few months later I felt like a new person, not the person I was before cancer, but someone who had transformed all those brand new “baby cells” after chemo into an athlete I didn’t know I could become. I began lifting heavy and loading my muscles and tendons as much as I could handle. I ran every workout April wrote for me, even the ones I looked at and thought “There is NO way…”
Since then, I have run a multitude of races and distances, including a marathon PR at Chicago in 2022, surprised and shocked by the amazing community support I received, spearheaded by my incredible coach. Today I am a stronger runner than I have ever been- before or after cancer. It hasn’t been easy, linear, or without setbacks, but no one’s running journey is predictable.
My previous blog post about cancer started with my 32nd birthday run, and this one will close with my 37th birthday run: this year I ran 37 happy, healthy, strong miles in this post-cancer body.

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: “What you do when the stadium is full is important, but what you do when the stadium is empty is a thousand times more important.”
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 won’t 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.
► It is the strength training that will help you get stronger, more resilient, have a better form, and make you injury resistant.
► 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.
► It is your daily nutrition that allows your body enough of the good stuff to repair itself and be appropriately fueled for your activity.
► It is the hydration throughout the day that will allow you to sustain a hard run even in the harshest of weather conditions.
► 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.
► 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.
► It is accumulating knowledge about the sport and the function of your body, which will allow you to understand what’s happening and why.
► 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.
► It is living a balanced life, one where your job, your family, and your friends won’t be neglected, and end up resenting you and your running.
► 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 we’ve 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.

No sugar coating it: Running in the heat and humidity of the summer sucks. It does. However, if we want to remain active during these challenging summer months of running and have any chance of having a solid racing season come fall, we must continue training. And to make hot weather running enjoyable and safe, the only way is by making substantial adjustments.
I’ve shared summer running tips every year since I began blogging, but this time I decided to do something different. I have gone through my previous writings on the issue and consolidated the tips. These, plus a handful of new ones I’ve added, bring the final count of summer running tips to 39.
To be clear, nobody expects you to apply all 39 of these hot weather running tips on every run. These are just guidelines and suggestions with very short explanations to get your thoughts started. I have included links to posts where I have explored the issues in more depth. And if you’re looking for more background or science behind these summer running safety tips, a quick Google search will point you in the right direction.
So, without further ado, here they are:
1 – Listen to your body – If you feel dizzy, nauseated, or overheated, don’t hesitate to stop, cut the run short, seek shade, ask for help, or just call it a day.
2 – Recognize heat stroke symptoms – Know the difference between exhaustion and heat stroke and familiarize yourself with warning signs like confusion, rapid pulse, or clammy skin.
3 – Hydrate all day – Hydration should be a 24/7 habit that keeps you close to fully hydrated by the time you start your GPS watch.
4 –Don’t overhydrate– Overindulging in water or sports drinks can cause hyponatremia, a condition in which diluted sodium levels may lead to seizures, coma, or worse.
5 – Use electrolytes– Supplementing with sodium, potassium, and magnesium helps your body retain and use the fluids you’re drinking more effectively.
6 – Run early or late – Run before sunrise or after sunset to avoid the most extreme heat and protect your body from overexertion.
7 – Monitor the heat index– Skip your outdoor workout if it’s over 98°F with more than 70–80% humidity, as your risk of overheating skyrockets.
8 – Slow down your pace – Running in the heat is harder, so let go of your pace goals and focus on effort instead of speed.
9 – Accept higher perceived effort – A rise in core temperature, not lactate or heart rate, becomes the main fatigue limiter in hot conditions.
10 – Use effort and time, not pace – In summer, pace and heart rate can be unreliable, so go by effort and run by minutes instead of distance.
11 – Recognize the signs of dehydration – Watch for fatigue, brain fog, darker urine, dizziness, or a dry mouth—these may all signal fluid imbalance.
12 – Prehydrate before long runs – Do not cram your hydration; it doesn’t work that way. Hydrate throughout the day and days, not just before your run.
13 – Rehydrate after running – After a sweaty session, replace fluids with water or an electrolyte drink. Not only as soon as you’re done but throughout the day.
14 – Dress light and bright – Light-colored, loose, and moisture-wicking clothing helps reflect sunlight and allow sweat to evaporate more easily.
15 – Train in the shade – Routes with trees or buildings that block direct sun can be 10–15°F cooler and far more comfortable, and safer.
16 – Freeze your gear – Put your shirt and hat in the freezer before a run to delay overheating and make the first few miles more tolerable.
17 – Take short breaks – Stop for 1–3 minutes during a hot run to drink, throw water on your head, or reset your effort perception.
18 – Use water for recovery – Jumping into a pool, cold bath, or even running through sprinklers post-run can drop your core temp and revive you.
19 – Know where the water is – If you don’t know where the reliable water sources are, run with a handheld bottle or hydration pack.
20 – Run indoors if needed – If conditions are extreme, choose a treadmill or indoor track to get your miles without the heat risk.
21 – Build heat tolerance gradually – It takes a few weeks to acclimate, so ease into hot-weather running instead of diving into hard efforts.
22 – Move workouts around when necessary – Move long or intense workouts to cooler days and use weather apps to plan smarter each week.
23 – Use a heart rate monitor – Heat elevates heart rate, so monitor it to avoid overexertion while running.
24 – Expect it to suck – The first few weeks of heat running will feel awful, but your body will adjust and it will suck less. Proceed with caution.
25 – Adjust your training plan – In very hot climates, push harder workouts like long tempos to the fall and focus on base-building instead.
26 – Exploit cooler days – When temperatures drop, use the opportunity for a strong tempo or threshold session to boost confidence.
27 – Don’t obsess over metrics – During summer training, forget about pace, Strava comparisons, or even distance—survival and consistency are the priority.
28 – Take advantage of trails – Shaded trails provide natural cooling, softer surfaces, and often more enjoyable running when it’s hot out.
29 – Eat hydrating foods – Boost your fluid intake by eating fruits and veggies like watermelon, cucumber, and oranges, which are 80–90% water.
30 – Beware of diuretics – Limit high doses of caffeine or alcohol around runs, as they increase urination and risk of dehydration.

31 – Set hydration reminders – Pair water intake with daily habits like brushing your teeth, meals, or use phone alerts to stay on track.
32 – Sip, don’t guzzle – Drink water steadily throughout the day and during your run to avoid bloating and improve absorption.
33 – Internalize year-round hydration strategies – Treat hydration like a year-round discipline, not just something to focus on when it’s hot.
34 – Know your sweat rate – If you’re a heavy sweater, you may need more fluids and sodium than the average runner.
35 – Pair hydration with daily habits – Combine drinking water with routines like meals, workouts, or bedtime to form easy-to-remember habits.
36 – Double instead of going long – On non-long run days, two shorter sessions may be safer than a longer push under the brutal heat. Consider it if needed.
37 – Use treadmill for quality work – Use a treadmill to maintain pace accuracy or intensity when outdoor heat makes it unsafe.
38 – Keep someone informed – Always tell a friend or loved one your planned route and expected return time, or use live tracking apps.
39 – Know the line between tough and dumb – Being smart and cautious during summer training keeps you healthy and able to run tomorrow.

In a WhatsApp running group, one of our friends recently shared an article from Men’s Journal Magazine praising the benefits of training in a fasted state. The sub-title alone was promising: The Science-Backed Benefits of Running on Empty, by Spenser Mestel.
I opened it as I thought of how pseudo-science has affected even the most mundane, easy runs lately. Most come from unqualified social media influencers or studies commissioned by companies that will benefit from their results. Dr. Tim Noakes is famous for questioning Gatorade’s science-based recommendations about the benefits of consuming Gatorade. And like that, examples are plenty.
Running on empty has its scientifically proven benefits (Image by ChatGPT)
We tend to forget that humans have been running for thousands of years. Hunted gatherers did so for hours while chasing an animal until it collapsed. Yet, they were able to pick it up and take it home to feed their families. They didn’t carry water packs to replenish every drop of sweat. They didn’t carry chews or gels to replace every calorie they burned.
Sure, we have evolved in those thousands of years. The bushmen of the Kalahari were not used to spending their day under air conditioning, sitting in front of a computer, or wearing shoes before they went hunting. But we haven’t entered devolution either. Our bodies were built to withstand a certain level of dehydration and caloric deficit.
I want to leave no room for doubt that I am not advocating against electrolyte replenishment, chews, gels, or any other product. God knows I could not have finished my last few marathons without the help of Maurten gels. What I am advocating against is their overuse, to the point where our bodies become unable to learn how to use their own resources.
Running on an empty stomach is not a fad passed around by social media influencers. Based on the article in question and the study on which it was grounded, it is a well-rounded premise that “fasted cardio” and “low-glycogen” training are similar but distinct practices that can offer real metabolic advantages if done right.
While skipping breakfast can be beneficial, you don’t have to do it for every run (Photo Pexels)
Mestel brings in Professor Richard J. Bloomer, Dean of the College of Health Sciences at the University of Memphis, to clarify the lingo. According to him, a “fasted state” can simply mean not eating for 10–12 hours, like overnight. But low-glycogen training goes further. It implies depleting your muscle glycogen stores, typically by limiting carbs over a longer period. Both approaches can shift your body’s fuel source away from sugar and toward fat, especially during lower-intensity sessions.
According to the study, these are some of the benefits:
Fat Adaptation: By skipping that pre-run snack or breakfast, your body is nudged into burning fat for fuel. Studies cited in the article showed that both men and women increased fat oxidation after exercising in a fasted state. Simply put, you’re teaching your body to tap into a steadier, more abundant fuel source.
Less Stomach Drama: Fasted runs can reduce gastric discomfort for those with fussy guts. No food means nothing sloshing around in there. It’s a win for morning runners who’d rather not eat at 5:00 AM just to avoid bonking at 6:00.
Convenience: This one isn’t science; it’s life. Rolling out of bed, lacing up, and getting it done before breakfast is just easier sometimes.
The science goes even deeper. In a 2010 study from the Journal of Applied Physiology, Beneficial Metabolic Adaptations Due to Endurance Exercise Training in the Fasted State by Van Proeyen et al., this wasn’t anecdotal evidence; it was a tightly controlled experiment. Two groups trained identically on bikes for six weeks. One ate carbs before and during workouts; the other trained fasted.
The result? While both groups got fitter, the fasted group showed superior metabolic adaptations. Their muscles improved at burning fat, their ability to use stored fat (even deep in the muscle) improved, and they kept blood sugar stable over long workouts. The carb-fed group? They didn’t show those perks.
Conclusion
It is not about skipping breakfast forever or starting every workout on an empty stomach. But if you mix in a couple of easy runs each week without eating beforehand, especially when effort is low and stakes are even lower, your body might thank you. You’ll become more metabolically flexible, able to use fat when needed and carbs when it matters most.
Don’t go overboard. It’s about teaching your body to adapt so it can rise to the occasion, whether chasing a PR or just running for joy.

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.
