the marathon

you don't need to run a marathon. but you need to run farther than you think you can. the distance doesn't matter. what matters is pushing past the point where your brain starts making excuses.
your body can handle more than you think
the human body is absurdly capable. research suggests that when you feel "done," you've typically used about 40% of your actual capacity. the remaining 60% is locked behind a psychological governor — your brain's way of keeping you safe from effort it deems unnecessary.
running longer distances is one of the most direct ways to confront that governor and tell it to shut up.
don't be stupid about it
this isn't a "go run 26 miles tomorrow" post. that's how you get injured and quit. the goal is to progressively run farther than you've ever run before, over the course of weeks or months.
if you don't run at all: start with a couch-to-5K program. 8 weeks. no excuses.
if you run casually: sign up for a 10K. train for 6-8 weeks.
if you run 10Ks: push for a half marathon. train for 10-12 weeks.
the key is structured progression. increase weekly mileage by no more than 10%. include rest days. get proper shoes. don't be a hero.
what the miles teach you
somewhere around mile 8 or 10 of a long run, something interesting happens. your body is screaming at you to stop. your mind starts bargaining — "you can walk just this one time." and you have a choice.
that choice is the entire point. not the medal, not the time, not the Instagram post. the moment where you choose to keep going when everything says stop.
that decision transfers to every other hard thing in your life. business, relationships, creative work. you build the evidence that you can push through discomfort, and that evidence changes your identity.
start this week
pick a distance that's 20% farther than your longest recent run. put it on the calendar. go do it.
if this resonated, share it with someone who needs to hear it.
