Running a marathon: your guide to smarter training


  • A study of 119,452 non-elite runners showed the effectiveness of a particular training method.
  • What made him conclude that? The fact that those who adopted it obtained better results in competition.
  • It relies on gradual increases in training load, consistency and slow runs that reduce the risk of injury.

Running a marathon is a big goal—and if you succeed, it’s a huge achievement. But getting there takes careful preparation. You need to stick to a solid training plan, give your body plenty of rest, and fuel yourself properly. And let’s face it: most of us aren’t elite athletes with access to professional support teams. That’s why making your training as effective as possible is a game-changer.

A recent study—the largest of its kind—uncovered valuable insights into how non-elite runners (yes, people like you) can prepare to conquer the iconic 42.2 kilometers. If you’re starting to train for a spring marathon, these science-backed tips could transform your approach.

What we learned from 120,000 runners

Researchers analyzed data from 119,452 amateur runners on Strava, tracking their preparation for major marathons like London, New York, and Dublin between 2014 and 2017. The goal? To uncover the habits that separate faster runners from the rest.

The big takeaway? Non-elite runners achieve better results by following the “pyramid” training method. This approach differs from the elite-favored 80/20 rule, where 80% of training is low-intensity and 20% is high-intensity. For recreational runners, the pyramid method offers a more practical, effective formula.

What is the pyramid method?

Think of a pyramid: the base is wide, and the peak is small. Your training effort follows a similar proportion:

  • 70% at an easy, “conversational” pace—perfect for long, slow runs.
  • 25% at a moderate pace—talking is limited to short sentences.
  • 5% at a high intensity—talking? Forget it. Breathing? Hard work.

This structure builds endurance safely, reduces the physical toll of intense workouts, and lowers the risk of injury.

Why it works for you

Dr. Ben Hunter of London Metropolitan University explains that since amateur runners don’t hit the weekly mileage of elites (160–220 km), the pyramid method is ideal. It helps you:

  • Build mileage without overloading your body.
  • Stay consistent, which is crucial for marathon success. Overtraining can derail your motivation.
  • Reduce injury risk, a common issue when increasing mileage too quickly.

How to use it in your training

  1. Increase mileage gradually
    Consistency matters, but ramping up too fast can lead to injury. Stick to the 10% rule: don’t increase your weekly mileage by more than 10% compared to the week before.
  2. Prioritize easy runs
    It’s tempting to go all-out, but most of your runs should be slow and steady. These runs build your aerobic base and aid recovery.
  3. Add intensity sparingly
    Save high-effort sessions for one or two workouts a week, like intervals or race-pace runs. Keep the total mileage in check.
  4. Listen to your body
    Injuries can derail even the best plan. If you feel pain or extreme fatigue, take a rest day or switch to a low-impact workout.

The key takeaways

Here’s what the research found:

  • Mileage matters. More training miles lead to better race times—but only if you don’t overdo it.
  • The pyramid method works. Focus on easy miles, with moderate and intense efforts in smaller doses.
  • Consistency is everything. Build gradually, and progress step by step.

Training for a marathon is a journey, and every step (literally) gets you closer to the finish line. Whether you’re chasing a personal best or just soaking up the experience, the pyramid method is your foundation. Stay consistent, trust the process, and start running—your finish line is waiting!
