I'd like to set the default speed of a race (while running) to equal that of an Ogre or less.

1) How do I find the speed of an Ogre?
2) Is the Ogre's given speed directly relate-able to the player's speed statistic? Or is it measured differently? If it is different...how do I compare?

The Speed of the vanilla Ogre is 18. The base speed of all actors (player, creatures, NPCs) is controlled by the GMST fMoveRunMult. This GMST affects all actors equally.

Athletics will affect your movement speed as well. Creatures do not have skills so the player has a slight advantage in this area.

Thanks, Pseron Wyrd.

Creatures do have skills, actually. The Combat entry in the CS sets all seven Combat skills, etc. -- you can test it at the console with GetAV.

Whether and how these skills actually function is something I haven't investigated, but I wouldn't rule out creatures getting Athletics benefits without some testing (or actual code diving).

While it's true that that one settings affects everyone, the base running/walking speed settings for creatures and NPCs are actually completely different. This is why a horse with Speed 50 runs a lot faster than a human with Speed 50.
