5 Marathon Mistakes to Avoid as a First-Time Runner

Taking on a marathon is an exhilarating challenge that brings a sense of accomplishment like no other. However, as a first-time runner, it’s crucial to steer clear of common pitfalls that can dampen the experience or even lead to injury. Here’s a guide to five mistakes you should avoid to make your marathon journey successful and enjoyable.

1. Ignoring Proper Training

One of the biggest errors that first-time marathon runners make is neglecting to follow a structured training plan. A well-designed programme is essential to prepare your body for the 26.2-mile challenge. Skipping long runs or failing to gradually increase your mileage can lead to fatigue and injury on race day.
  • Start with a reasonable mileage base and build up gradually.
  • Incorporate long runs to simulate race conditions.
  • Don't forget to include rest days to allow your body to recover.


By following a structured training regimen, you will not only build endurance but also gauge your pace and learn how to fuel your body effectively.

2. Neglecting Nutrition

Nutrition plays a pivotal role in your running performance. Many first-time marathoners make the mistake of overlooking their diet. What you eat can significantly affect your energy levels and recovery.
  • Focus on carbohydrate-rich foods to fuel your long runs.
  • Ensure adequate hydration in the weeks leading up to the race.
  • Experiment with race-day nutrition in your training to see what works best for you.


Understanding your body's nutritional needs can give you the advantage in both training and on marathon day.

3. Overtraining

While it’s important to train for the marathon, overtraining is a common mistake that can be detrimental. Many first-time runners push themselves too hard, leading to burnout, injuries, or chronic fatigue.
  • Listen to your body and be mindful of signs of fatigue.
  • Incorporate cross-training to improve your strength and reduce the risk of injury.
  • Utilise periodisation in your training to balance intensity and recovery.


Avoiding overtraining starts with respecting your body and allowing it to recover adequately. Remember, rest days are just as essential as your training days.

4. Failing to Test Gear

Another common blunder is not testing gear during training runs. Many runners head into the marathon with new shoes or clothing, only to face discomfort or chafing. Familiarity with your gear can be the difference between a successful race and a miserable experience.
  • Invest time in finding the right pair of running shoes that suit your foot type.
  • Wear clothing that is breathable and won’t cause chafing.
  • Use your training runs to break in new gear well ahead of the race.


Getting comfortable with your gear can greatly enhance your performance, ensuring you focus on the run rather than your discomfort.

5. Skipping Race Day Preparations

The final mistake many first-time marathoners make is underestimating the importance of race day preparation. From how you approach the day to the mental preparation needed, overlooking these elements can lead to unnecessary anxiety.
  • Plan your race day logistics in advance, including travel, gear, and nutrition.
  • Arrive early to familiarize yourself with the environment and avoid rushing.
  • Visualise your race strategy to set the right mindset.


Preparation before the big day instills confidence, allowing you to focus on running your race rather than worrying about the unknown.
By avoiding these five common mistakes, you will set yourself up for a successful and enjoyable marathon experience as a first-time runner. Remember to focus on proper training, nutrition, listening to your body, testing your gear, and preparing effectively for race day. Each step you take will bring you closer to crossing that finish line with pride and accomplishment. Happy running!
