I saw a short of a marathon in extreme heat. The runners got spray with water to cool them down. Does this replace the effect of sweating?

I might even work better.
You sweat to cool yourself down. Changing a liquid to a gas requires energy. The cooling effect of sweating is when the water on your skin evaporates and take the required energy from your skin so your temperature drops. The effect is quite clear with alcohol that evaporates a lot faster and the cooling effect is obvious.
The process the excrete sweat to the skin does not have a cooling effect, it is just a way to get the water there.
You will skip the absorption of water in the body and transportation to the skin. The water you sweat out will contain salt that you also need to consume along the water.
There is a limited capacity per unit of time of absorption of water so if you sweat to much you can get dehydrated.
