I was wondering, how fast would somebody have to go to run on water? I don't mean with a Waterwalk spell but just running and not going under. I think it should be able to be done, you'd just need to have a very high speed.

at risk of getting all physics-y on you it could be done theoretically for a short distance before gravity did it's work and you dropped into the water (if you're talking 'on' the very surface then an infintely small distance).
However if you're talking about self propulsion then it's not possible, as you'd need to displace large amounts of water to move forwards. If you had a large force pulling you along it's possible to 'plane' along the water (like water skiing with your feet) |

It is possible, and it depends on the structure of the thing running on the water. We have all seen boa constrictors swimming across the water, some lizards can run across the water. Sveral insects and spiders can even skim on the water.
If you are a guy in armor, you are going to have to be able to move fast enough that your pressure onto the surface of the water is greater than the force of gravity and friction from the water. If you can beat both of those, you are easily able to give your self a direction, turning how ever may be a bit of a problem, but agian this is more related to the interaction at the point of contact between runner and water.
Basically...a person would have to be really fast. Other questions to ask:
salt water or fresh water?
What is the temperature of the water?
What is the atmospheric pressure temperature and humidity?
How big are your feet?
How heavy are you?
Is there any wind?
Is the water choppy or smooth?
In the ocean you would have to be able to go at least a factor of 4 faster than a waterskier, though I would have to find and dust off my college physics book to be able to give you a better answer than that.
If the water is cold enough you could go at any speed.(its called ice) |
Run faster! The Kobolds are catching up! |

Oh perhaps 90 miles per hour might work.
As already pointed out it depends on many factors. The type of water, the type of footware also applies, as does the weight.
Objects heavery then water can stay above for a time. The best example is skipping stones. They are not going 90 miles per hour however for a time are moving fast enough that the weight is not large enough to break though the surface of water to sink on first contact. A person however normally has a far greater weight then a flat stone per square inch hitting the water. |

| I mean a character in the game, running fast enough to not break the water tension. What kind of speed would they need to have to do that? |

Well not having any proof that FR water has a water tension, I would offer a speed of 3600 per round (an that based on run x4 ). |

| Thank you! I had a feeling it would be somewhere aroiunf that high. I just thought it would be funny if somebody were to run on water. |
