What Is A Half Marathon In Km?

Running a marathon can be an incredibly fulfilling experience for runners. It requires months of training, dedication, and discipline to prepare for the 26.2-mile race. However, not everyone is ready to tackle a full marathon. That’s where the half marathon comes in.

A half marathon is a long-distance race that covers 21.0975 kilometers or 13.1094 miles. It’s a popular distance for runners who want to challenge themselves but are not yet ready for the full 42.195 kilometers (26.219 miles) of a marathon.

In this article, we’ll dive deeper into the world of half marathons and explore what they are, how they compare to marathons, and why you should consider running one.

What Is a Half Marathon?

A half marathon is a road race that covers a distance of 21.0975 kilometers or 13.1094 miles. It’s half the distance of a full marathon, hence the name “half marathon.” The race typically starts with a mass start, with all runners starting at the same time. Half marathons can be held on roads, trails, or a combination of both. The courses are marked with distance markers and water stations for runners to refuel along the way.

Half marathons are becoming increasingly popular around the world. In fact, the half marathon is now the fastest-growing race distance in the United States. This is because they provide a challenging but achievable goal for runners who are looking to push themselves beyond a 10K or 5K race.

How Does a Half Marathon Compare to a Full Marathon?

While both the full and half marathons are long-distance races, there are some key differences between the two. The obvious difference is the distance. A full marathon is twice the distance of a half marathon, and it requires much more training and preparation. Training for a full marathon can take anywhere from 16 to 20 weeks, while training for a half marathon can be done in 12 weeks or less.

Another difference between the two races is the pace. Half marathons tend to be run at a faster pace than full marathons. This is because the shorter distance allows runners to push themselves harder without the risk of burning out too soon. The average pace for a half marathon is around 9 to 10 minutes per mile, while the average pace for a full marathon is around 10 to 11 minutes per mile.

Finally, the experience of running a half marathon versus a full marathon can be quite different. While both races require dedication and perseverance, completing a full marathon is considered a significant achievement in the running community. A half marathon is still a great accomplishment, but it may not receive the same level of recognition as a full marathon.

Why Run a Half Marathon?

There are many reasons why someone might choose to run a half marathon. Here are just a few:

  • Personal challenge: Running a half marathon is a significant challenge that requires dedication, discipline, and hard work. It’s a great way to push yourself beyond your limits and achieve a goal that you may have thought was impossible.
  • Health benefits: Running is a great way to stay in shape and maintain a healthy lifestyle. Training for a half marathon can help you lose weight, lower your blood pressure, and reduce your risk of chronic diseases like heart disease and diabetes.
  • Community: Running is a social sport, and running a half marathon is a great way to connect with other runners in your community. You’ll meet people who share your passion for running and can support you throughout your training and on race day.
  • Fundraising: Many half marathons are associated with charitable organizations, and runners can use their participation as an opportunity to raise money for a cause they care about. It’s a great way to combine your passion for running with your desire to make a positive impact on the world.
  • Variety: If you’ve been running shorter races like 5Ks and 10Ks, a half marathon is a great way to mix things up and try something new. It’s a challenging but achievable distance that can help you break out of your comfort zone and discover new strengths and abilities.

How to Train for a Half Marathon

Training for a half marathon requires dedication, discipline, and a solid training plan. Here are some tips to help you get started:

  • Build up your mileage gradually: If you’re new to running, start with shorter distances and gradually increase your mileage each week. Aim to increase your mileage by no more than 10% per week to avoid overtraining and injury.
  • Incorporate speed work: To improve your running speed and endurance, incorporate interval training and tempo runs into your training plan.
  • Strength training: Strength training can help improve your running form, prevent injury, and increase your overall strength and endurance.
  • Rest and recover: Rest and recovery are just as important as training. Make sure to schedule rest days into your training plan and prioritize sleep and nutrition to support your body’s recovery.
  • Listen to your body: Pay attention to how your body is feeling and adjust your training plan accordingly. If you’re feeling fatigued or experiencing pain, take a break and give your body time to recover.


Running a half marathon can be a rewarding and challenging experience. It’s a great way to push yourself beyond your limits, connect with other runners in your community, and achieve a personal goal. With the right training plan, dedication, and perseverance, anyone can complete a half marathon and enjoy the many benefits of running.
