The closing stage of a race is the most exciting part of our sport, right? In those minute fractions of a second, medals are won or lost, and those tiny moments define people's lives. To coach our athletes for that final kick, we frame it as, you've got to be strong enough to arrive at that last stage with the least amount of damage accrued.
People think what you're seeing when athletes sprint at the end is just this natural speed, when actually, it's that they had to arrive at the stage of "one lap to go" really, really strong so they're able to use that speed. If they don't expend too much energy early on—battling for position or making moves when they shouldn't—and they can stay relaxed and confident, then they're set up for the optimal kick. Some of that is pure racing instinct.
