Building Your Aerobic Base

Building Your Aerobic Base

By Coach Adolfo Salgueiro

Let\’s start by stating something basic that even veteran runners tend to forget: The Marathon is a 99% aerobic event. Yes, even Ekiud Kipchoge and the East Africans who run around him run the marathon as an aerobic endeavor.

Having a solid aerobic base to sustain continuous action for 26.2 miles is one of the keys to a successful marathon. And when I state \”successful,\” I don\’t mean setting a PR; I mean finish. Sure, we all know someone who has finished a marathon without training, but those are outliers, and most of those go through a sufferfest during their race. So, don\’t take any cues from them.

Your aerobic base is the cornerstone of your long-distance running journey. Think of it as a pyramid\’s broad, solid foundation, supporting the peak over which speed and performance are built.

Developing an aerobic base requires time, work, and patience. It covers hundreds, if not thousands, of miles and comes from years of engaging in activities that keep your heart rate elevated for long periods of time. Many runners achieve this base through previous activities in sports like soccer or swimming, while others have honed it just by running over the years. A strong aerobic base is essential to improving your speed and excelling in endurance events.

Running beyond the correct rate of perceived effort, performing all your long runs at race pace every single week or running your repetitions and intervals with all your might are not conducive to developing a solid aerobic base. It is counterproductive and not only won\’t make you faster in the long run, it may lead to injury.

The aerobic base can be developed by:
• Running consistently
• Learning where your conversational pace lies
• Accepting you must go slow to run fast
• Trusting the process

 As your aerobic base develops, you will:
• Become a more efficient runner
• Become a faster runner
• Improve the rate of lactate removal
• Improve muscle and energy output

I firmly believe you shouldn\’t go all out on your training runs, drills, and reps. Since your body needs to recover to realize the adaptations of your efforts and still keep the training moving forward, ending a rep or a training session on the verge of collapse is not the best practice. When you do so, you put your body through extreme stress, which will require a longer period of recovery. It would be best if you ended the rep knowing you could have gone even faster. Finish the workout knowing you could have gone an extra rep or two is a better strategy.

When you train for a race, that effort is in the future; you are working towards that goal. This means you train at today\’s fitness level, not at the level you expect to be at race time. Focus on the prize.

Once race day is here, after a tapering period during which you are recovered and ready to go, you give it your all on race day. You are not saving anything for tomorrow. You invested your mind, body, and resources through a test of fitness and will. Then, you cross the finish line at the edge of your endurance limit.

In Conclusion

Running slow is counterintuitive. It feels weird when you know you could be running faster. It takes practice to go slow. Anyone can run itself to the ground by sprinting every day and racing their training runs. There is no merit in that. What takes guts is to accept that you must be patient, play the long game, and be willing to defer your gratification so you can enjoy your running for a very long time.

Sure, these are fundamental concepts for most runners, but we all need to be reminded of the obvious at one point or another to remain grounded during a difficult training cycle.

American Runners are Slower than Ever

American Runners are Slower than Ever

By Coach Adolfo Salgueiro

A couple of weeks ago I came across a statistical mega study that confirmed what the title of this blog post states. Using over 34.6 million results from over 28 thousand races, researchers Jakob Andersen and Vania Andreeva Nikolova, sliced and analyzed the data in multiple ways to reach their conclusion.

As I glanced through the research, I realized I started reading with preconceived notions on what they would find. More runners, unhealthier athletes, aging, gender gaps. The usual. Back in my youth, when I ran marathons in the 3:30s in the mid-1980s, I finished around the 50 percentile of finishers. A stat I just read from the Chicago Marathon stated that 18% of runners finished sub-3:30 this year. An obvious shift. I must say all my biases were addressed in the study and the conclusion still holds.

If after reading my take on this study you want to delve into the minutiae and the data, you can find the research paper in its entirety by clicking here.

This thorough study includes racing in the four most popular distances (5K, 10K, half and marathon), and races with more than 2000 finishers between 1996 and 2016. The reasons why this data was selected, the terminology and methodology of its handling, is detailed in the study, if you are interested. One more thing, researchers state this study took place because the deteriorating health of the American populations is an important topic to be studied and they wanted to find if this reality is reflected in the finishing times of races.

The study could have been a great episode of Discovery Channel’s Mythbusters TV show, as it takes the time to disprove many of the preconceived notions we may have about these numbers. These are:

1 –        The proportion of women participants is increasing, and women are slower in general: Men speed is decreasing at a faster rate than the women increment in participation. If this trend continues, by 2045 both sexes will be at an equal average pace.

2 –        People with inappropriate fitness level just walk the races: The study found the proportion of participants finishing races on every distance, at a slower than the average brisk walking pace is rather consistent throughout the years, so there is no statistical difference.

3 –        Just the slow are getting slower: An easy idea to assume but the study measured the average final time for the 100th, 1000th, 2000th and 5000th finisher on each race throughout the years of the study, on both sexes, and concluded the fastest females have slowed down 9.87% while males have done so at a 9.94% clip.

4 – The average age of the participants is increasing and older equals slower: The average participant age has increased from 37 to 41, so the study analyzed not just the finishing times for these 4-year gap, but for every 4-year gap on all ages as well as every single age and concluded this could not be the sole reason of the slow down.

So, if these are myths, what are is slowing down American runners?

The study considered the parameters of adult obesity, teenage obesity, diabetes and hypertension, and average annual medical expenditure. It found an across-the-board direct correlation with the slowdown. The authors make sure to emphasize that these are just correlations and by no means they can infer the condition of each runner, yet the numbers are very clear on what is happening as the population is getting heavier and unhealthier.

The study concludes the following:

  1. The average American runner has never been slower (across gender and distance).

  2. This effect is not due to the increase in female participants or people who run slowly or walk the race.

  3. Signs of poor health are highly correlated to the decrease in speed, though they cannot with certainty say that these are the causes for the slowdown. And if they have causal nature that they show the full picture.

The study was led by Jens Jakob Andersen and assisted by Vania Andreeva Nikolova. Andersen is a former competitive runner and statistician from Copenhagen Business School. Nikolova holds a Ph.D. in Mathematical Analysis.
