If you’ve ever wondered about how long a marathon will last and how long it will last, you’re not the only one. No matter if you’re just beginning to learn about running or a fitness fanatic, or just someone who is interested in marathons, knowing what distances, times and the preparation required is crucial.
In this article we’ll discuss the number of miles and kilometers it takes to complete a marathon and why it is a specific distance as well as the time it takes to complete one, and suggestions to prepare you for the race.
What Is the Official Marathon Distance?
The official marathon distance is 26.2 miles, which equals 42.195 kilometers.
That exact measurement — 26 miles and 385 yards — has been the global standard since 1921.
To put it in perspective:
- A 5K race is just 3.1 miles.
- A 10K race is 6.2 miles.
- So, a marathon is more than eight times longer than a 5K and about four times longer than a 10K!
If you liked to run an entire marathon on a track with a length of 400 meters it would require approximately 100 turns in order to finish the full distance.
Why Is a Marathon 26.2 Miles Long?
The marathon hails from ancient Greece where a Greek messenger named Pheidippides ran 40 kilometers (nearly 25 miles) from the town of Marathon, Greece to Athens to deliver news of a victory during battle. And in the first modern Olympics, in 1896, organizers took a page from this tale and added a race of some 40 kilometers. Then, the next year, came a universally accepted distance: 26 miles and 385 yards (42.195 kilometers), which became the gold standard when it was put in place during the 1908 London Olympics for a marathon that started at Windsor Castle and ended at Olympic Stadium.
How Long Does It Take to Run a Marathon?
How long it takes to run a marathon depends on experience, fitness, and pace. Here’s a general breakdown:
Runner Type Average Marathon Time
Elite Runners Around 2 hours
Intermediate Runners 3 to 4.5 hours
Recreational Runners 4.5 to 6 hours
Walkers or Beginners 6+ hours
If you maintain a 10-minute-per-mile pace, your marathon time will be around 4 hours and 22 minutes.
The world record marathon times currently stand at just over 2 hours for men and about 2 hours 14 minutes for women — an incredible athletic achievement.
Factors That Affect Marathon Timing
When planning your marathon, keep these factors in mind:
- Training consistency: The more consistent your running schedule, the better your performance.
- Pacing strategy: Starting too fast often leads to early fatigue.
- Course type: Flat city courses are faster than hilly or trail routes.
- Weather conditions: Heat, wind, and humidity can slow you down.
- Nutrition & hydration: Proper fueling prevents “hitting the wall.”
- Recovery: Rest days are crucial for muscle repair and endurance.
Remember — marathon running is as much a mental challenge as a physical one.
How Long Does It Take to Train for a Marathon?
If you’re planning to run your first marathon, you’ll need 12 to 20 weeks of structured training.
- Beginners: 16–20 weeks (to build endurance gradually)
- Intermediate runners: 12–16 weeks
- Experienced runners: 10–12 weeks
A good marathon training plan includes:
- One long run per week
- Easy recovery runs
- Speed or interval training
- Rest days
- A tapering period before race day
How to Estimate Your Marathon Finish Time
You can estimate your marathon finish time using the Riegel formula:
T₂ = T₁ × (D₂ / D₁)¹·⁰⁶
Where:
- T₁ = your time for a shorter distance (like 10K)
- D₁ = that race distance
- D₂ = 42.195 km (marathon distance)
Example:
If you ran a 10K (6.2 miles) in 60 minutes:
T₂ = 60 × (42.195 / 10)¹·⁰⁶ ≈ 4 hours 36 minutes
This gives you a realistic goal time for your marathon.
Why Running a Marathon Is So Special
It’s an impressive feat to run 26.2 miles. It fosters discipline, toughness and confidence. The distance represents resiliency, determination that reaches beyond the race itself.
Indeed, each year millions of runners just like you from all across the world run marathons and in doing so, prove to you through their example that anyone can do it too if they have some determination and put in a little training.
