Katie Ledecky Smashes 800-Meter Freestyle Record Like It Was Nothing

US swimmer (and possible mermaid) Katie Ledecky has done it. She just smashed the 800-meter freestyle world record by clocking in a mind-blowing time of 8 minutes and 4.79 seconds.

Check out the video below that shows her easily coming in first and looking only as winded as I appear after I've walked up just one flight of stairs.

LOOK HOW FAR AHEAD SHE IS OF THE WORLD RECORD! WHAT IS THIS? A WORLD RECORD FOR ANTS?!

Seriously, she just smashed that record like it was this easy to do so:

Let's put it this way -- Katie was so far ahead, Rio could have held her gold medal ceremony while everyone else was catching up.

OK, hyperbole aside, her victory was nothing short of a landslide, even though it was not done on solid land.

Katie's nearest opponent, Great Britain's Jazz Carlin (what a name!), finished a full 11.38 seconds after her, which is an enormous margin when it comes to the Olympics.

Also, worth noting is that Katie just became the first Olympian in 48 years to make a clean sweep of the 200-meter, 400-meter and 800-meter freestyle races, joining former Olympian Debbie Meyer.

That's a lot freestyling. Like, I don't think Eminem could freestyle for that long and hard, you know what I mean?

Congrats Katie! Enjoy your fourth gold from Rio and your fifth overall!
