Endurance vs. Speed: Which Matters More in Marathon Training?

2 years back Nara 6 minutes reading time

Marathon training requires a strategic combination of endurance and speed to achieve significant results.

Many runners wonder which of these elements should receive the most attention in training, especially when the goal is to successfully cross the finish line.

Therefore, this article analyzes the pros and cons of prioritizing each aspect and how to balance them for optimized performance.

The importance of endurance in marathon training

Endurance is undoubtedly the foundation of marathon training.

Without a solid foundation, it is impossible to support the 42,195 km efficiently.

Building this physical capacity involves gradually increasing training volume, strengthening the cardiovascular system and muscular capacity.

According to a study published by Journal of Applied Physiology in 2020, practicing long runs at moderate intensity improves VO2 max and running economy by up to 15%.

This shows that endurance is a determining factor in maintaining a constant pace during the race.

Additionally, long-distance running trains the body to use fat as an energy source, which is essential in long-distance races.

This process, known as fat adaptation, reduces the risk of premature exhaustion.

Resistance also positively impacts mental balance.

Marathons require focus and discipline, and runners who build a solid foundation are more likely to maintain focus even in the most challenging moments.

The ability to resist mental fatigue is as important as physical endurance.

Finally, resistance work helps strengthen muscle groups that withstand repetitive impacts.

This reduces the risk of injury and improves stability, essential elements for those seeking longevity in running.

Benefits of resistance:

• Improved aerobic performance.
• Greater energy savings.
• Reduced risk of injury due to muscle adaptation.

Speed: the factor that defines your final time

While endurance is essential, speed also plays a crucial role in marathon training.

Working on speed doesn't just mean running fast, it also means improving your ability to switch between different intensities and maintain a high pace at critical moments in the race.

Interval training is one of the best strategies for developing speed.

Short, high-intensity sprints alternated with recovery periods optimize anaerobic performance, increasing the ability to maintain a competitive pace for long periods.

Additionally, speed training helps improve running mechanics.

More efficient strides and improved posture result in less energy wasted, a critical factor for runners looking to optimize their times.

Another benefit of speed is its impact on the athlete's confidence.

Therefore, achieving higher speeds during training creates a sense of progress and motivation, which are essential factors for maintaining consistency in training.

Benefits of speed:

• Better rhythm control.
• Greater efficiency in overtaking and acceleration.
• Development of explosive strength and localized muscular endurance.

A simple table illustrates how interval training can be structured:

Interval	Distance	Intensity	Rest
Sprint 1	400m	90% of effort	1:30
Sprint 2	600m	85% of effort	2:00
Sprint 3	800m	80% of effort	2:30

The balance between endurance and speed

A complete runner is not built on endurance or speed alone.

Finding the ideal balance is the real challenge.

For this, training periodization is essential.

This method organizes training into cycles that prioritize different physical capabilities over time.

In the initial phase, the emphasis should be on running volume to build a solid endurance base.

In the intermediate and final phases, the inclusion of specific speed training is essential to simulate real race conditions and improve overall performance.

During balancing, it is crucial to monitor the body's response.

The ideal combination varies depending on factors such as age, injury history, and current condition.

Professional monitoring can be crucial in adjusting your training and avoiding overdoing it.

Integrating endurance and speed also improves motivation.

Alternating between long workouts and sprints keeps training dynamic and challenging, avoiding monotony and increasing overall efficiency.

A comparison table helps clarify how to prioritize each aspect throughout the cycle:

Phase	Main focus	Training example
Base	Resistance	Long, continuous runs
Preparation	Resistance and strength	Moderate climbs and shots
Competition	Speed	Intervals and test simulations

Personalization: the key to success

Every athlete has unique demands and limitations.

Therefore, personalizing marathon training is essential.

A beginner runner, for example, should prioritize gradually increasing endurance to avoid injuries and develop a solid base.

On the other hand, experienced athletes can devote more attention to interval training and specific speed work.

Consulting a coach or qualified professional helps you develop a strategy that effectively combines training, respecting the athlete's individual profile.

Additionally, monitoring metrics like heart rate, pace, and perceived exertion can provide valuable insights into your workout progress.

Technology also plays a crucial role in personalization.

GPS watches, apps, and performance analysis platforms enable real-time adjustments, helping athletes quickly correct flaws.

The science behind choice

An interesting fact revealed by research from Stanford University shows that runners who balance endurance and speed training are 25% more likely to improve their marathon times.

This reflects the importance of integrating both elements into a well-founded, strategic plan.

Finally, it’s worth remembering that rest and recovery are just as important as training.

Excessive volume or intensity can lead to overtraining, impairing performance and increasing the risk of injury.

Active recovery, such as light walking and stretching, also speeds up the body's adaptation, ensuring consistent progression.

Dedicating one day a week exclusively to rest or low-impact activities can make all the difference.

Final considerations

In the debate between endurance and speed, what really matters in marathon training is the intelligent integration of the two components.

A balanced approach, tailored to individual needs and based on scientific data, can lead any runner to their best performance.

Investing in planning, monitoring, and continuous adjustments is the way to overcome limits and reach the finish line with confidence and satisfaction.

After all, a marathon is much more than a race; it's a journey of self-discovery and overcoming obstacles.
