👋🏻 Hey Reader!

Wednesday August 19 · Short edition

Yesterday we talked about choosing your fall race. Today I'm bringing you the other half of that conversation — and it's what I promised you.

At the London Diamond League, Josh Kerr ran the mile in 3:42.66 and broke a record that had stood untouched for 27 years. The interesting part isn't the time. It's that he announced it beforehand.

Why it's called Project 222

222 seconds = 3:42

The goal wasn't "run fast." It was an exact number, split across four laps with specific time ranges.

🎯 The three pieces of Project 222

① Pacing designed to the second

His team didn't go out to "see what happens." They broke the record into exact fragments — every 400 m with a specific range, accounting for accumulated fatigue across four all-out laps. It's the same thing any marathon coach does calculating 5K splits, except here the margin of error is measured in fractions of a second.

② Gear tuned to his biomechanics

Spikes and race kit fitted to him and to that track. It connects to what we already know about running economy: shoe weight, plate stiffness, fabric friction — every variable translates into measurable energy cost. In a sub-four-minute mile, every watt saved counts.

③ Public pressure as a tool

They named the project and talked about it before the race. That inverts the usual relationship with pressure: instead of suffering it passively, it becomes a public commitment that structures the entire preparation. It isn't motivational magic — it's behavioural consistency.

The science behind the 3:42.66

No public announcement holds a pace if the body can't. A systematic review with meta-analysis confirmed that strength training consistently improves running economy across different speeds [PMID:38165636].

And a controlled trial added what matters most for a mile: strength improves the durability of that economy — how well you hold it once you're already fatigued [PMID:40016936]. Translation: not losing your stride on the last lap.

🏃 How you apply it (without the sponsorship)

You're not going to break a world record. But the framework works just as well for going under 25 in the 5K or running your first sub-4 marathon.

1	Turn your goal into seconds, not feelings Not "I want to run faster." Instead: "10K in 47:30, at 4:45 per kilometre, first 3K controlled at 4:50."
2	Announce it to someone who'll hold you to it No press conference needed. Your training group is enough. Well-aimed pressure doesn't paralyze you — it organizes you.
3	Build the strength that holds pace under fatigue Two sessions a week. Not optional if time allows — it's the difference between holding your pace at km 35 or falling apart.
4	Visualize the discomfort, not the finish line Kerr didn't visualize crossing the line happy. He visualized the third lap, when the legs get heavy and the mind starts hunting for excuses.

Henri's take

I constantly see runners with the physical capacity to lower their times protecting themselves with conditional language: "let's see if I can", "I'm going to try". That soft language protects the ego, but it dilutes commitment.

I don't ask my athletes for world records. I ask them to say the exact number, out loud, to someone who's going to call them six weeks later and ask how it's going. That small social discomfort tends to be the difference between a plan that gets done and one that gets abandoned in the first hard week.
