The Details That Break Barriers

Nike is at it again.

Tomorrow, Faith Kipyegon—arguably the greatest middle-distance runner of all time—is going after a sub-4:00 mile. No woman has ever done it. She already owns the mile world record, but the team around her thinks she can knock nearly eight seconds off it.

“I’m a three-time Olympic champion. I’ve achieved World Championship titles. I thought, What else? Why not dream outside the box?” said Kipyegon, a Kenya native and mother to a young daughter, said in Nike’s announcement. “And I told myself, ‘If you believe in yourself, and your team believes in you, you can do it.’”

What’s fascinating isn’t just the goal—it’s how they’re trying to get there.

Nike’s not leaving any meaningful detail untouched. They’ve built a one-of-one 3D-printed sports bra using thermoplastic polyurethane. Custom carbon-spiked shoes with “advanced foams” and lighter plates. An aerodynamic fly suit, headband, arm and leg sleeves, each designed to reduce drag with 3D-printed “aeronodes” that manage airflow.

They even studied her world record in Monaco and found that she only drafted for the first 900 meters. This time, they’ll surround her with rotating pacers—some likely fresher, some behind her—to give her every second possible.

This isn’t just science—it’s precision.

It’s knowing what matters and ignoring what doesn’t.

And that’s the real story here. Because while Nike’s team is focused on every inch of fabric and gram of weight that could slow Faith down, there are also a few things they’re choosing not to do:

• They’re not trying to replicate every training method she used five years ago just because it once worked.

• They’re not obsessing over how it looks to others—they’re obsessing over how it works for her.

• They’re not testing what’s popular—they’re engineering what’s effective.

• They’re not guessing—they’re modeling and measuring.

Instead, they’re curating the right inputs for the right athlete, at the right moment in time.

And that’s where this becomes more than sport science. It’s a principle you can use—whether you’re chasing Olympic gold or building your company, your relationships, or your next big move.

Because high achievers often make the same mistake: they copy everything except the part that actually matters.

They fixate on minor optimizations—perfecting the font on the pitch deck, listening to seven different podcasts about morning routines, copying someone else’s business framework—while ignoring the hard, unsexy truth of what would really move the needle.

That’s the hard part. Knowing which details are worth your obsession.

In the Life’s Algorithm framework that’s core to the book I’m working on, this is a cornerstone: precision matters more than volume. And personalization beats imitation, every time.

Here’s what you can borrow from Kipyegon’s attempt:

1. Study what’s worked—for you.
Nike modeled her own world record, not someone else’s. Want to improve? Start with what you’ve done well before. Reverse-engineer your best week, your highest-performing month, your clearest decisions. Build from your data.

2. Identify your drag.
For Faith, it’s aerodynamics. For you? Maybe it’s distractions. Emotional overreactions. Lack of recovery. What’s slowing your momentum that you haven’t measured?

3. Customize what carries you.
They didn’t hand her the best-selling spike. They built one around her stride and feedback. Your systems—your calendar, your habits, your team—should do the same. Most people don’t need to work harder. They need systems tailored to their actual goals and constraints.

4. Make bold attempts—even if they’re not official.
This race won’t be world-record eligible. Still, Nike calls it a legacy moment. Sometimes the most meaningful milestones in our lives are unofficial: the pitch you finally make, the conversation you’ve avoided, the boundary you finally enforce.

So here’s your challenge this week:

What’s your version of the “aeronode”? What’s the detail in your life or work that—if refined—could create a disproportionate impact?

More importantly:
What are the details you’re obsessing over that simply don’t matter?

Faith may or may not break the barrier. But she—and the team around her—remind us that the people who win the long game don’t just work harder. They work smarter, on the right things.

And those are almost always invisible to everyone else… until they aren’t.
