I admit to using an online tool to figure out how many days are left between when I start writing this and Halloween, the day of the marathon. That’s the magic of the Internet: Laziness always wins when it comes to math problems. You’re probably thinking — besides “He can’t calculate the number of weeks left on his own?” — “If you’re training for a marathon, shouldn’t you know off the top of your head how many weeks are left?” Most people follow a training regimen, usually 18 weeks of checking off boxes that say “Run X miles.”
