It's at the borders of pain and suffering that the men are separated from the boys.
But maybe you are a grinder who wants to grind. If that's the case, then you don't need a 9-month training plan, you just need to make running like brushing your teeth. Run lots, mostly easy, sometimes hard. You find the time, squeeze it in. Start counting the miles in months, get weary, get the lines on your face, the aches in your joints. Drink coffee like its your job. You run today, every day, unconcerned whether it might take 9 months or it might take 5 years or it might take 10 years. It rains on you. The sun burns your face. The running gets all mixed up with the rest of your life, even attached to the heart of your being. People look at you sorta funny and wonder if you are sick. You walk up stairs at your job and you feel your muscles like cords, taught and straining, tired and strong. Even your heart sometimes feels tired, walloping away in that bird-chest.
