A marathon is one of the most iconic and challenging sporting events worldwide. Whether you’re a runner, a fan, or simply curious about the race, you may wonder how long a marathon is and what it takes to run one. In this article, we will not only answer the question “how long is a marathon?” but also provide historical context, training tips, and advice for first-time marathoners. Let’s dive in!
What Is the Exact Distance of a Marathon?
The official marathon distance is 26.2 miles or 42.195 kilometers. This distance is universally recognized by all major running organizations, such as the International Association of Athletics Federations (IAAF), the governing body for track and field. So, whether you are running a local marathon or an international event, the race distance remains constant.
Why Is a Marathon 26.2 Miles?
The marathon’s distance is rooted in both legend and history. The story goes back to Ancient Greece, where a soldier named Pheidippides is said to have run from the battlefield of Marathon to Athens to deliver the news of the Greek victory over the Persians. The distance he ran is believed to be around 25 miles, but it wasn’t until the 1908 London Olympic Games that the distance was standardized to 26.2 miles. The additional 0.2 miles were added to the race route to allow the British royal family to view the start and finish of the race.
The History of the Marathon
The modern marathon was inspired by the ancient Greek tradition, but the first official marathon as we know it today was introduced during the 1896 Athens Olympics. The event was created to celebrate the revival of the Olympic Games, and the course was 40 kilometers (about 24.85 miles). However, in subsequent Olympics, the distance was adjusted to 26.2 miles, and it has remained unchanged ever since.
Today, marathons are held all over the world, with major events like the Boston Marathon, New York City Marathon, Berlin Marathon, and Tokyo Marathon attracting runners from every corner of the globe.
How Long Does It Take to Run a Marathon?
One of the most common questions marathoners face is how long it takes to finish a marathon. The time it takes to run a marathon depends on various factors, including a runner’s experience, fitness level, and how well they’ve trained.
Average Time for a Marathons
For the average runner, completing a marathon is no small feat. The following is a breakdown of typical marathon times for different types of runners:

- Beginner Runners: If you’re running your first marathon and are not aiming to compete for the fastest time, the average finishing time for beginners tends to be between 4 and 6 hours. Many first-time marathoners pace themselves more slowly to avoid burnout and injury.
- Experienced Runners: For those with marathon experience, the average finishing time can range between 3 and 4 hours. These runners are typically well-trained, and they have built up endurance and speed through years of running and competing.
- Competitive Runners: Elite marathoners—those competing at the highest levels—complete marathons in 2 to 3 hours. These athletes are highly trained, and their speed allows them to achieve incredible times.
- Casual Runners: For runners who are walking, jogging, or just aiming to finish, marathons times can stretch out to between 5 and 7 hours. Many marathons have a generous cut-off time of 7-8 hours, allowing all runners to complete the race at their own pace.
World Record Marathon Times
- Men’s World Record: The fastest marathon ever run by a man is 2:01:39, set by Eliud Kipchoge of Kenya during the 2018 Berlin Marathons. Kipchoge is widely considered one of the greatest marathoners of all time.
- Women’s World Record: The women’s marathon record is held by Brigid Kosgei, also from Kenya, who completed the 2019 Chicago Marathon in 2:14:04. Kosgei’s remarkable achievement broke the previous record held by the legendary Paula Radcliffe for over 16 years.
How to Prepare
Running a marathon is a huge challenge that requires physical and mental preparation. If you’re thinking about running one, you’ll need to commit to training, proper nutrition, and taking care of your body throughout the process.
1. Start Training Early
Training for a marathon typically takes 12 to 20 weeks, depending on your fitness level and experience. The key is to start slow and gradually increase your mileage.
- Beginner Runners: For those new to running, it’s best to start with a walking program and slowly incorporate running intervals. Over the weeks, you can increase the amount of time spent running each week.
- Intermediate/Advanced Runners: If you’ve already completed shorter races, such as 5Ks or 10Ks, you’ll need to follow a structured marathon training plan that includes longer runs, speed workouts, and recovery periods.
2. Plan for Weekly Runs
A typical marathon training schedule includes 3 to 5 running sessions per week, including one long run. The goal is to gradually build up to running 18 to 20 miles in your longest training session.
- Short Runs: On shorter days, aim for 3 to 5 miles. These help build endurance without exhausting your body.
- Long Runs: Your long run should be progressively longer, allowing your body to adapt to the demands of running 26.2 miles. For example, you might start with 8 miles and gradually increase it by 1 or 2 miles every week.
3. Nutrition for Marathon Training
Proper fueling is essential for training and performance. Your diet should include:
- Carbohydrates: Carbs are your primary source of energy during long runs. Focus on foods like pasta, rice, and fruits to fuel your runs.
- Protein: Protein helps with muscle recovery after runs. Include lean meats, legumes, and dairy products in your diet.
- Hydration: Dehydration can drastically impact your performance. Drink plenty of water throughout the day, and use electrolyte drinks during your long runs.
4. Cross-Training and Rest
While running is key, cross-training can help improve your overall fitness and reduce the risk of injury. Activities like cycling, swimming, and strength training complement running by building different muscle groups and increasing cardiovascular endurance.

Equally important is rest. Your body needs time to recover from long training sessions. Be sure to schedule rest days into your weekly training schedule.
What to Expect on Race Day
Race day is the culmination of all your hard work. It’s filled with excitement, nerves, and anticipation. Here’s what you can expect.
1. The Start Line
- Excitement and Nerves: The start of the marathon can be overwhelming, with thousands of runners lined up. Take a deep breath, and remind yourself that you’ve trained hard for this moment.
- Wave Starts: Many marathons use wave starts to group runners by estimated finish time. This helps reduce crowding at the beginning of the race and ensures smoother pacing.
2. Water Stations and Aid Stations
- Most marathons have water stations placed every 1.5 to 2 miles along the course. These stations provide water, sports drinks, and sometimes energy gels or snacks to help replenish lost fluids and nutrients.
- Pace Yourself: Even though you’ll be tempted to drink from every station, it’s important to pace yourself. Taking a few sips at each station is enough to stay hydrated.
3. The Finish Line
- The Final Stretch: As you approach the finish line, you may feel exhausted, but the excitement and sense of accomplishment will give you a boost. Keep your focus on the finish line, and don’t forget to smile!
- Celebrating Your Achievement: Crossing the finish line is a monumental moment, whether you’re finishing in 3 hours or 7. Every runner who completes a marathon is a champion.
