Average Marathon Times By Age: A Comprehensive Breakdown

Running a marathon is an impressive achievement for any runner, regardless of experience level.

As marathons have grown in popularity and accessibility, it is natural to wonder about the average marathon times across age groups.

This information can be helpful for those interested in comparing their own performance to their peers or simply curious about how age impacts running abilities.

Understanding the average marathon times by age can be valuable for goal setting, training adjustments, and personal improvement.

For most men, finishing a marathon in under 4.5 hours is considered a solid accomplishment, while for women, a time just under 5 hours is a strong finish.

The average marathon time for men across all age groups is 4:19:00, while for women, it is 4:08:09.

Further breakdowns by age reveal varying trends in average times and provide insights into how age and ability levels affect marathon performance.

Importance of Age in Marathon Performance

Age plays a significant role in marathon performance as it is often associated with physical changes and varying levels of fitness. As runners get older, factors such as muscle strength, cardiovascular endurance, and overall stamina can be affected.

While age is an important factor, it’s been observed that runners who can finish a marathon in under three hours experience reduced age-related decline in performance, according to a study from Runner’s World.

This highlights the importance of consistent training and maintaining high levels of fitness throughout one’s running career.

Average marathon times vary considerably by age group. For example, in one specific race, the average finish times by age group were as follows:

It’s crucial to understand that these averages are representative of a specific race, and individual results may vary. The global average marathon time is 4:29:53, with men averaging 4:21:03 and women averaging 4:48:45 according to a Marathon Handbook study.

Furthermore, the average age of marathon runners has increased over the years from 38 to 40.

While marathon finish times generally increase as runners get older, it is important to note that it is still possible to run strong races at advanced ages with the right training and dedication.

Average Marathon Times By Age Groups

18-24 Years

Runners within the 18-24 age group typically have fast marathon times due to their youth and physical abilities. This age group tends to have competitive athletes striving for personal bests and goals.

25-34 Years

The 25-34 age group includes a mix of younger and more experienced runners, leading to a wide range of finish times. Many runners start to hit their marathon peak during this age range, accumulating both fitness and knowledge from prior races.

35-44 Years

As runners enter the 35-44 age group, they may begin to face more age-related challenges in maintaining or improving their times. However, with consistent training and adaptability, many athletes in this bracket can still maintain strong performances.

45-54 Years

In the 45-54 age group, some runners start to slow down due to natural aging and decreased recovery abilities. But with proper training and smart race strategies, it’s still possible to achieve impressive marathon times within this age range.

55-64 Years

Marathon runners between the ages of 55-64 often experience a decline in performance due to the natural aging process. Nonetheless, dedicated athletes can still clock in admirable times by adapting their training regimen and focusing on injury prevention and recovery.

65-74 Years

The 65-74 age group typically experiences more significant slowdowns in their marathon times. Despite this, many runners in this age bracket continue to compete for their own personal achievements and maintain a strong commitment to the sport.

75+ Years

Runners aged 75 and above are truly inspiring, demonstrating incredible perseverance and a love for the sport. While their marathon times are generally slower due to age-related factors, their dedication and enthusiasm remain strong, serving as an inspiration to all.

Factors Affecting Marathon Times

Many factors can influence an athlete’s marathon time, including training regimen, experience, nutrition, and running economy. In this section, we will explore these factors in more detail.


A well-structured and consistent training program is crucial for marathon success. Proper training helps to build endurance, strength, and speed. Different aspects of training, such as duration, intensity, and frequency, play significant roles in improving an athlete’s marathon time:

  • Duration: Increasing the length of long runs gradually helps to build endurance.
  • Intensity: Incorporating speed workouts and hill training can improve overall speed and strength.
  • Frequency: Running consistently throughout the week allows the body to adapt more effectively to training stress.


Marathon performance often improves with experience. Seasoned runners tend to have better race strategies, pacing, and mental toughness, which can lead to faster marathon times. According to Runner’s Goal, participants with more marathon experience tend to have faster average marathon finish times across different age groups.


Nutrition is another essential factor for marathon performance. A balanced diet, proper hydration, and effective fueling during long runs and races can help runners maintain a consistent pace and prevent the dreaded “wall” that many marathoners face in the latter part of the race. Key aspects of marathon nutrition include:

  • Carbohydrates: The primary fuel source for aerobic exercise, which should be consumed in sufficient amounts.
  • Protein: Crucial for muscle recovery and repair, especially after long runs and intense workouts.
  • Hydration: Staying properly hydrated throughout training and on race day helps to maintain optimal performance.
  • Electrolytes: Replacing lost sodium and other electrolytes during long runs and races is essential for avoiding muscle cramps and maintaining fluid balance.

Running Economy

Running economy refers to the efficiency of a runner’s movement and energy use while running. Factors that can influence running economy include biomechanics, flexibility, and body composition. Improving running economy through strength training, mobility exercises, and maintaining a healthy body weight can contribute to faster marathon times. As per OLYRUN, professional marathon runners often set their personal records between the ages of 28 and 33, which could be attributed to their experience and optimized running economy.

Improving Marathon Times at Different Ages

Setting Realistic Goals

When it comes to improving marathon times at different ages, setting realistic goals is essential. Based on the average marathon times for men and women, you can determine a reasonable target time for your age and sex. It’s important to remember that these times are for recreational runners and may not apply to elite athletes. Consider your current fitness level, past running experience, and available training time to set achievable goals for yourself.

Adopting Age-Specific Training Strategies

Different age groups may require different training strategies to optimize their marathon performance. As you age, your body undergoes various physiological changes that can affect your running abilities. According to a study in Runner’s World, it’s possible to limit the age-related decline in performance to less than 6 percent per decade, at least between 35 to 60 years old, by maintaining consistent training routines. Some age-specific training strategies may include:

  • Gradually increasing weekly mileage for younger runners
  • Incorporating strength training and flexibility exercises for older runners
  • Adjusting running intensity and duration based on individual abilities

Incorporating Recovery and Injury Prevention

Recovery and injury prevention play a crucial role in improving marathon times at different ages. Proper rest and recovery help the body adapt to the stress of training and minimize the risk of overuse injuries. Some tips for incorporating recovery and injury prevention into your training plan include:

  • Ensuring adequate sleep and nutrition
  • Scheduling regular rest days and incorporating cross-training activities
  • Performing dynamic stretches and foam rolling to improve flexibility and reduce muscle tension
  • Listening to your body and modifying your training plan as needed to avoid overexertion

By implementing these strategies, you can work towards improving your marathon times regardless of your age.
