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.
