Marathon Training

Marathon Training

Etixx, the perfect support for your marathon challenge

Whether you are planning to run your first marathon or you are an experienced long-distance runner, for an extreme physical effort like the marathon you need energy (and a lot of it) – nutritious food is what will keep you going during the 26.2 miles 42K. Balancing diet and training is essential as the big day nears.

Discipline, perseverance and the right foods

Although certainly one of the more demanding endurance events, the marathon is also one of the most popular, requiring discipline and stamina to succeed. Preparing for the race you will need to find a balance between training, healthy food and plenty of rest. On marathon day itself, you will burn in excess of 2000 calories, so will need to consume some form of carbohydrate whilst running and will certainly need to practice your race day nutrition in training. If you stick to both your training and nutrition plans, you will reach the finish line with a smile.

Eating well is important for a marathon but how do you know which foods are right for you? There are lots of information sources containing thousands of often contradicting tips and tricks that can make it even harder for aspiring marathon runners.

At Etixx we create products backed by scientific research. For example, our Carnitine supplement has been specifically developed so marathon runners can more effectively burn fat as a fuel and prevent fat mass increases. All our products are developed and tested by a team of scientists and top athletes before being released for sale.

How the advice is built up

How to prepare for long-distance races? Have a look at our diet plan

Each athlete has its own requirements based on its goals, current physique, experience with sports nutrition and specific complaints.
Besides these personal influences, there are similarities we found across our innovation teams like Global Sports Communication and all the amature marathon runners we involved in our product testings.
Based on these findings, we created 2 levels of advice:

  • Essential advice: Contains basic sports nutrition recommendations related to your sport. This is recommended for each marathon runner no matter which level or personal needs.
  • Advanced advice: Contains more advanced sports nutrition and supplement recommendations for athletes looking to optimise their performance. Made for those who are ready to go to the next level and are aiming for challenges which are just within their reach.

How to make sure you fuel up during a race

Performance in prolonged exercise is reliant on the availability of muscle glycogen and therefore it can be important to take on carbohydrates during exercise to replenish fuel stores. If no carbohydrates were consumed during prolonged or intense efforts, muscle glycogen stores would be depleted after ~90min. The amount of carbohydrate you should take during exercise depends on the length of the session or event.

  • Exercises < 1 h(15): not necessary to consume carbohydrates during exercise .
  • Exercises 1-2 h: 30 g carbohydrates per hour exercise.
  • Exercises 2-3 h: 60 g carbohydrates per hour exercise.
  • Exercises >2.5-3 h: up to 9 0g carbohydrates per hour exercise.

  • Ideal isotonic thirst-quencher
  • For optimal hydration (electrolytes & fluid) and fuelling (carbohydrates)
