The Insane Women's 4x100m Relay | Fraser-Pryce DESTROYS the Final Leg

One hundredth of a second decided gold from silver — and the reason is buried in three baton exchanges most viewers never notice. This breakdown reveals how relay efficiency, not raw speed, shapes the final result from the opening gun. Anchor mechanics, exchange zone timing, and sprint biomechanics: the full technical picture behind a dramatic relay finish. How does a team with imperfect exchanges still win against a squad running clean baton work? This analysis walks through every phase — first-leg splits, zone timing costs, cadence data, and the final-leg mechanics that closed a two-metre gap in the last forty metres. By the end, you'll watch every relay final differently.
