How Long Is A Marathon? (& How Long Does It Take To Run One?)

Ever wondered exactly how long a marathon is, or why the distance is what it is?

Or maybe you’re curious about how long it takes to run one and how you can train for your best possible time.

In essence, a marathon is 26.2 miles of pure guts.

As a coach and marathoner, I see the marathon as more than a race—it’s a real test of endurance, strategy, and mental strength

If you’re thinking about your first marathon or trying to beat your best time, here’s everything you should know about the distance, pace, and training.

How Long is a Marathon?

We already established that a marathon is exactly 26.2 miles (or 42.195 kilometers). That last 0.2 miles might not seem like a lot, but after 26 miles, it feels endless!

Trust me, every step of that last 0.2 miles counts.

The marathon distance isn’t random; it actually has a pretty interesting backstory

Originally, marathon races were based on the legendary run of Pheidippides, a Greek soldier who supposedly ran about 25 miles from the battlefield of Marathon to Athens to deliver news of victory.

He collapsed after delivering his message, but his run inspired the marathon we know today

However, the modern distance of 26.2 miles was set during the 1908 London Olympics. The race was extended by 1.2 miles to accommodate the British royal family’s desire to race to finish right in front of their viewing box at the Olympic Stadium.

And just like that, the standard marathon distance was born!

How Long Does It Take to Run a Marathon?

Your marathon finish time will depend on your fitness, experience, and pace.

For some, a marathon is about speed; for others, it’s just about finishing

For elite runners, a marathon typically takes a little over 2 hours. The world record is 2 hours and 35 seconds, set by Kelvin Kiptum (may he rest in peace) of Kenya at the 2023 Chicago Marathon

For most recreational runners, it takes around 4 to 5 hours to complete.

Here’s a quick look at marathon times based on different paces:

• 5-minute mile pace: 2:11:06
• 6-minute mile pace: 2:37:19
• 7-minute mile pace: 3:03:32
• 8-minute mile pace: 3:29:45
• 9-minute mile pace: 3:55:58
• 10-minute mile pace: 4:22:11

Average Marathon Finish Time

The average marathon finish time for recreational runners is around 4 hours and 32 minutes. Men tend to finish slightly faster, averaging 4 hours and 22 minutes, while women average 4 hours and 48 minutes.

However, as I’ve already explained, this varies widely depending on the runner’s experience, training, and the course conditions.

But don’t worry about averages; just finishing a marathon is a huge achievement!

Here’s a breakdown of average completion times based on data from Runner’s World and the National Runners Survey:

Men (20-29 years): 1:52 – 2:02

Women (20-29 years): 2:10 – 2:20

Men (30-39 years): 1:56 – 2:06

Women (30-39 years): 2:14 – 2:25

Men (40-49 years): 2:00 – 2:10

Women (40-49 years): 2:20 – 2:30

Men (50+ years): 2:05 – 2:20

Women (50+ years): 2:25 – 2:40

These times are averages, so individual results can vary based on fitness, training, and race conditions. Use these as benchmarks to set realistic goals and track your training progress.

What is a good marathon time for beginners?

For beginners, finishing in 4.5 to 5.5 hours is a good target. This range allows first-timers to complete the marathon at a comfortable pace without putting too much pressure on hitting a specific time goal.

For your first marathon, focus on finishing strong, enjoying the experience, and learning about pacing. Every marathon finish is an achievement to be proud of!

What are the main factors that affect marathon time?

Marathon completion times are influenced by several factors, including:

• Age: Generally, younger runners tend to have faster average times, but runners of all ages can achieve excellent results with training.
• Fitness Level: The more you build your aerobic endurance and strength, the better prepared you’ll be to sustain a faster pace over the marathon distance.
• Training Intensity: Adding long runs, speed work, and strength training to your routine can make a big difference.
• Course and Weather Conditions: Hilly courses, high temperatures, or windy conditions can make a marathon more challenging and affect your time.

These factors combined will determine your finish time, so focus on consistent training and preparation to make the most of your marathon experience.

How to Train for a Marathon

Training for a marathon isn’t just about running the distance—it’s about preparing your body and mind for one of the most challenging physical feats you can undertake. Whether you’re a seasoned runner or gearing up for your first marathon, here’s how to set yourself up for success:

1. Build Your Base: Make sure you’ve been running regularly for at least six months before starting marathon training. Aim for 3-4 runs per week, with a weekly mileage of at least 15 to 20 miles.
2. Follow a Plan: Most marathon training plans last between 16 and 20 weeks. They’ll gradually increase your weekly mileage and include a mix of long runs, speed work, easy runs, and rest days.
3. Incorporate Long Runs: Long runs are the cornerstone of marathon training. They help you build endurance and mental toughness. Start with 8 to 10-mile long runs and gradually increase by 1-2 miles each week until you can comfortably run 18-20 miles before race day.
4. Cross-Train: Activities like cycling, swimming, or strength training are great ways to improve your fitness without overloading your legs. Strengthening your core and leg muscles will improve your running form and prevent injuries.
5. Rest and Recover: Recovery is just as important as running. Include rest days in your plan and listen to your body. Stretching, foam rolling, and getting enough sleep are crucial for preventing injury and maintaining energy levels.
