This is a partial list of things that take less time than Katie Ledecky had to relax after she touched the wall of the pool at the Olympic Aquatics Stadium in Rio de Janeiro and waited for someone to finish second in the 800-meter freestyle final:
— Usain Bolt running 100 meters
— John Force drag-racing a Funny Car over the quarter-mile
— Cordarrelle Patterson returning a kickoff for a touchdown
— Cleaning a cat's litter box
I know that last one for a fact.
Ledecky won her second consecutive gold medal in the 800 — and the fifth gold of her career overall — by a margin of nearly 12 seconds over silver medalist Jazmin Carlin of Great Britain.
