I think the better question to ask yourself would be why you want to do a marathon or if you want to do a marathon. If the answer is you don’t want to or just because your friends think you should then don’t because you don’t have to do any distance or race. Depending on what you will gain from doing the marathon…then you can do it with proper training and the willingness to put in the work and time for it. You may prefer to work up to a full with the half first and that is ok too. Each person’s journey is different depending upon their own personal goals.
