Unfortunately, water is more than 700 times denser and 55 times more viscous than air, meaning that water has a higher resistance to flow and is more difficult to maneuver through [1]. These qualities of water contribute to the force that swimmers must constantly battle – drag.
Why is it so hard to run in water?
Water Resistance and TemperatureWater is much denser than air, so there is much more resistance preventing people from being able to move through it quickly and freely. This makes it so much more difficult compared to other land sports.
Why can’t they move fast through the water?
Speed of your sprint depends on the speed you can tear through air molecules. Water has more molecules than air. So it is tough to move through water.
How fast would a person need to be to run on water?
The Italian researchers figured out how a 5-foot-7, 145 pound human could run on water just like that lizard. On Earth, the human's legs would have to press down against the water at more than 67 miles per hour which, the researchers explain, is 15 times the force our legs are capable of producing.
Is swimming the toughest sport?

Is it harder for muscular people to float?
The Ratio of the weight of a body to the weight of the water it displaces is its specific gravity. If the specific gravity is @ 1.0 the object is suspended in the water, neither sinking or floating. How does this effect a person's ability to float? Those with more body fat and less muscle usually float more easily.
Is it possible to run so fast you run on water?
Ground like dirt wood or concrete. Because the attractive forces between the molecules are strong enough to hold all of them in place in a liquid these forces are weaker.

Why do we run slower in water?
Viscosity is a fluid property that affects the resistance that an object encounters during motion. In the case of underwater running, viscosity explains why you move significantly slower in water than on land. It also can offer resistance up to 15 times the amount of resistance on land.
