The marathon is a legendary test of human endurance and resilience, and it may seem like everyone on your social feed is itching to complete one lately. If you’re ready to hop on the bandwagon and see what the marathon is all about, here’s some essential info to get you started.
How Long Is a Marathon?
The full marathon is a 26.2-mile-long endurance event. With an official distance of 26 miles and 385 yards (or 42.195 kilometers), it’s one of the longest distances for conventional races. Anything over that is considered an ultra marathon.

This precise measurement traces back to the 1908 London Olympic Games, where organizers extended the race distance to cover the ground from Windsor Castle to White City Stadium. This was a race no one wanted to miss — including King Edward VII and his family — so it was essential that the royal family could view the start from their balcony. (1)
What Is a Marathon?
A marathon is a long-distance running race. It’s one of the most iconic and challenging athletic events, attracting participants of all abilities from all over the world.
The marathon’s origin traces back to ancient Greece, where legend has it that a messenger named Pheidippides ran from the battlefield of Marathon to Athens to deliver the news of a military victory against the Persians. I’m exhausted just thinking about his journey in his military gear.
Upon arriving in Athens, the messenger announced that they’d won, before collapsing and dying from exhaustion. This legendary feat inspired the modern marathon, and the race’s distance was standardized in 1921. (1) What a dramatic first marathon.

The marathon isn’t just for elite athletes. Every day runners who are first-time marathoners and seasoned wheelchair athletes can also participate.
Wheelchair racing involves specialized equipment, including lightweight wheelchairs designed for speed and maneuverability. These athletes often start the race ahead of the runners to avoid congestion on the course and officials record their race time separately.
A note on accessibility: Many formal marathon races require entry fees and particular qualifying times. Some do not have provisions for wheelchair athletes, and they may also have unclear or nonexistent standards for nonbinary and trans athletes. However, other organizations — like the New York City Marathon — have a nonbinary division for athletes to compete in. Check out races near you to learn about their qualification and inclusion standards.
How Long Does it Take to Run a Marathon?
The time it takes to complete a marathon varies greatly depending on several factors. Elite runners can run a marathon in around two to two and a half hours (yes, you read that right). Elite athlete Eliud Kipchoge held an average time of 2:52 per kilometer (or 4:35 per mile) for an entire marathon. (2)
On the other hand, recreational runners may take anywhere from three to six hours or even longer to finish. However, various factors can influence your marathon time.
Fitness Level and Training
Fitness level and training quality heavily influence marathon performance. Long-distance running requires aerobic endurance, muscular strength, and mental toughness. (3) Athletes who train consistently with structured programs are much better equipped to handle the physical demands of the race.

If you’ve put in the effort and have remained consistent throughout your training, you’ll likely show up well-prepared on race day, ready to smash your goals. A well-prepared marathon runner is more likely to sustain their pace throughout the race and achieve a faster finishing time. However, if you’re undertrained, you may exhaust yourself in the beginning and have trouble finishing.
Course Difficulty
The layout of the marathon course significantly impacts performance — and therefore, your run time. Courses with challenging terrain, such as steep hills or uneven surfaces, pose additional obstacles that can slow runners down and increase fatigue.
In contrast, fast and flat courses with minimal elevation changes enable runners to maintain a consistent pace and optimize their performance.

For example, the Boston Marathon is notorious for its hilly terrain, while the Chicago Marathon is one of the fastest and flattest races in the U.S. I’d go with the flatter option, as it’s a much better opportunity to hold an even pace throughout — and the easier, the better, to be honest. But that’s always a personal choice, and if you’re aiming for a challenge…just make sure you train on similar terrain as your race.
Weather Conditions
Weather conditions influence performance and the overall race experience. Extreme temperatures — whether hot or cold — affect how much energy you use, your hydration levels, and how your body regulates temperature. High humidity can lead to heat-related stress and increase the risk of dehydration and heat-related illnesses. (4)

Similarly, strong winds can prevent forward progress, basically blowing you in the wrong direction and slowing you down. You’ll likely have to adjust your pacing strategies, especially on more exposed sections of the course. (4) Rain, on the other hand, may affect traction and visibility, requiring you to adjust your footing and pacing accordingly.
Nutrition and Hydration
When you’re in the middle of marathon training, you are what you eat — and drink, for that matter. Endurance running places substantial demands on your body’s energy levels, requiring adequate fueling before, during, and after the race. Carb loading in the days leading up to the marathon can help replenish glycogen stores and boosts energy. (5)
Poor nutrition and hydration practices, such as inadequate fluid intake or reliance on sugary snacks, can lead to an upset stomach, muscle cramping, or poor performance. (5)
Race Strategy
Successful marathon performance requires a consistent race strategy that balances pacing, fueling, and mental strength. Starting too fast can lead to exhaustion early on. On the other hand, conservative pacing and negative splitting — where the second half of the race is faster than the first — can help you maintain energy reserves and finish strong.
Effective fueling strategies involve consuming carbs and fluids regularly to prevent bonking (or energy crashing) and dehydration.

Mental Toughness
The marathon is all about mental resilience. Enduring months of rigorous training and pushing through the discomfort of the distance requires mental toughness and determination.
Overcoming doubts, distractions and negative thoughts during the race is essential for maintaining focus and staying on pace. (7)
Average Marathon Times
RunRepeat’s study of marathon results included more than 100 million race results from 1986 to 2018. These times don’t include specific stats from nonbinary runners, who often must compete with other athletes of their assigned gender at birth. (8)
The average marathon time is 4:32:49. However, this doesn’t consider gender, age, experience level, or preparation strategies. Here are the average marathon times according to experience level, (8)
How to Train for a Marathon
Thinking of running a marathon for the first time? That probably means you’ve competed in — or at least run on your own — shorter races, perhaps including a half marathon. When you’re getting serious about completing the length of a marathon in its entirety, you’ll need a marathon training plan.

Stretch, Stretch, Stretch
Stretching is something I neglected for so long in my training journey, and I know I’m not the only one. But stretching is essential for flexibility, mobility, and muscle recovery. Exercise shortens your muscles, leading to stiffness and mobility issues over time. All things being equal, looser muscles help with a greater stride, allowing you to run faster for longer with less risk of injury. (9)
Tight quadriceps are common among runners. This tightness can throw you off balance and increase your risk of injury. Focusing on stretching this muscle improves your alignment and flexibility.
Here are some stretches to pepper in before and after your run, along with some of the best stretches generally. (Yes, you’ll need them after those long, long runs.)

Mix Up Your Runs
Vary your training runs to build fitness and prevent boredom and monotony. For specific guidance based on your experience levels, you might also want to get in touch with a running coach before hitting the starting line.
Consider incorporating the following runs into your weekly schedule as you gear up to tackle to distance of a marathon:
Long Runs: These are the foundational components of training. They should build endurance and mental toughness. Perform these runs at a comfortable, conversational pace and gradually increase the distance throughout the workout program. They’re a great time to practice fueling and hydration.
Tempo Runs: Also known as threshold runs, these are structured workouts to improve lactate threshold (performing at 90 percent of your maximum heart rate) and running economy (the amount of oxygen your body uses). This pace is comfortably difficult, challenging enough to elevate heart rate and breathing but sustainable for a prolonged period. These tempo runs improve aerobic capacity and increase endurance. (10)
Interval Runs: These involve alternating periods of high-intensity effort with recovery or rest times. These workouts typically consist of repeated intervals of hard running followed by intervals of jogging or walking for recovery. Intervals improve anaerobic capacity and speed by challenging the body to perform at maximal or near-maximal effort for short bursts. (10)
Recovery Runs: Easy recovery runs are low-intensity, short-duration runs at a relaxed pace to facilitate recovery and promote active recovery between more challenging sessions. They allow you to flush out metabolic waste products and loosen tight muscles. Easy runs improve blood flow and circulation, reduce delayed muscle soreness, and enhance recovery without adding too much stress to your body. (10)
Build Those Muscles
Adding strength training to your schedule as you get ready for your first marathon finish is essential to aid injury prevention and improve running efficiency. (11)
Focus on running-specific exercises that target key muscle groups such as the core, hips, glutes, and legs. Include exercises like:
Squats
Rows
Add hip strengthening drills to enhance stability and power.
Train Your Mind, Too
It’s all in your head when it comes to marathon preparation. While you may be physically fit, it’s your mind that sets you up for success on race day. (12)

Practice Fueling
Experiment with different fueling strategies during your long runs and race-specific workouts to determine what works best for you. Energy gels are a popular option, but they don’t sit well in everyone’s stomachs.
Test various brands of energy gels, chews, tablets, and sports drinks to find products that sustain your energy without causing tummy troubles. If you don’t enjoy gels, you can always experiment with other options like dates, dried fruits, bananas, honey stinger waffles, energy bars, gummies, or even baby food. It’s all about finding what works for you without leaving you in search of a bathroom on your runs.

Prioritize Rest Days as Much as Training Days
Rest days are crucial for allowing your body to recover from the rigors of training for any running event — especially a marathon. (14) Schedule at least one or two rest days per week to give your muscles a break from the physical demands of running.
[Read More: Can You Train for a Marathon On a Treadmill? An Expert Running Coach Teaches You How]
Use rest days to do some active recovery activities such as strengthening, foam rolling, yoga, or low-impact cross-training to promote circulation and muscle relaxation without placing extra stress on your body.
