Hang on Sofia, you’re going for a ride.

This is a very cool video of Sofía Gómez Uribe doing a “rock run” across the ocean floor.  Sofia is a world record holding freediver and shows us how it’s done.  In this video she carries a large rock and dives to a depth of 60 feet.  Then she runs up through a trench until she is back at the surface.  Try holding your breath while you watch this.
