So which stroke is fastest? Take a wild guess…

The Olympic Games channel on its Facebook page posted a four-way comparison video of the four swimming strokes — freestyle, butterfly, breaststroke, backstroke — and surprise, surprise guess which one came out fastest?

Yup, the freestyle.

And the video they used for the comparison was from the London Games, and Nathan Adrian’s win in the 100 freestyle.

It’s never NOT a good time to sit back and watch that race again … and again … and again… It will forever give me chills.
