Marathons are really popular due to the reason that they are the peak of human performance. You can only run a marathon if the manner in which you have currently chosen to live your life has been optimized to a large degree. Completing a marathon would make you feel extremely special, as if you have achieved something incredible in your life that no one else would be able to measure up to. That said, preparing for a marathon is an essential component to succeeding in this regard.
One thing that you should bear in mind is that winning a marathon is something that only massively successful athletes would be able to do. What you should focus on instead is completing the marathon without any major delays. It’s only when you do this that you would manage to acquire a better understanding of how such races work. The thing about long-distance races is that using relay runs to prepare for them can often be useful. They can get your body used to the strain that often comes with such things, eventually making you fit enough to be capable of running such a distance.
You can’t just randomly embark on a marathon and expect to find a high level of success. In fact, doing so would lead to some serious injuries that you would have a pretty hard time dealing with. Instead of being this cavalier about the race, prepare for it carefully by hiring a running coach and also monitoring your diet so that it doesn’t have any carbs in it that would slow you down. Preparing for a marathon is a marathon in and of itself, and you should mentally ready yourself for it.
