Sprinters are often told to relax. Don’t tighten up. Run free.
It’s not wrong. But it’s only half the story.
Bud Winter was writing about it in the 1940s, his ideas eventually published as Relax and Win in 1981. Tom Tellez built it into his work with Carl Lewis and others through the 1980s and 90s. The word has been in the sprint coaching vocabulary for the better part of a century, and for good reason.
But good sprinting is not just relaxed. It is incredibly violent.
The jaw is loose. The shoulders are rocking and rolling. The Achilles is as stiff as steel. The glutes are producing forces that would buckle most structures. Those things coexist in the same body, in the same step, at the same moment.
One is quantity — force, rate, and direction. The other is quality — efficiency, and the absence of unnecessary tension. Elite sprinting demands both simultaneously. That is the paradox. And it’s where most athletes struggle.
The challenge at speed is not learning to relax. That’s relatively easy. It’s learning to be simultaneously fluid and ferocious — to apply huge forces fast at minimal cost. This is a paradox, but in elite sprinters those two things coexist. In fact, I believe it is the single most important factor separating the elite [9.85–10.00] from the super-elite [sub 9.85].
Under pressure, the two rarely survive together. Forces degrade, or efficiency disappears — and with either one, the paradox breaks.
So what to do? If this paradox is the key, how do we coach it?
“Relax” can work as a cue, particularly later in a race when the quantity has already been established. But it can’t stand alone. Cues work best in sequence — force and aggression early, ease and fluidity late. In that order, ‘relax’ gives the system something to release into.
The solution is not a better single word.
It is the right words, in the right order.
