 We explain what you should know when preparing for a marathon. This is Henry. His big dream is to participate in a marathon. Although he runs regularly, this is a competition that Henry is not ready for yet. Starting now, he therefore keeps important things in mind to prepare in the best way. Henry knows a marathon takes patience. That's why he is scheduling enough preparation time to familiarize his body with the exertion and get adjusted to it. Especially his bones and tendons have to adapt to the training. It is therefore important that the running units are increased slowly. After all, Henry wants no injuries. A good training plan helps him prepare effectively and expediently. It includes a combination of long and short runs as well as power training and recovery periods. Henry is aware. Speed is not everything. Long and slow endurance runs that optimize the energy metabolism are much more important. In order to stay mentally strong, his running partner Jenny supports him during the training. For together, running is much more fun. Already he is frequently testing his running shoes and comfortable clothes that he wants to wear on the competition day. With supplementary strength training, Henry is reducing the risk of injury and improving his running style. Regeneration phases between the training units are also very important. They help Henry with his muscle development and prevent immunodeficiency. To ensure that Henry's energy during the race never diminishes, he mostly eats healthy foods with a high amount of carbohydrates. These provide him with many nutrients that his body needs for the training. Two weeks before the marathon, Henry significantly cuts down the frequency of his training units. This phase of tapering is especially important so that when the competition day comes, Henry can use his full strength. Fit and well-prepared, Henry's dream can now be realized. Three, two, one, go!
