This mod will add a metal crate to the porch of the Prospector Saloon in Goodsprings. Inside the crate there will be some chokers. Equip then un-equip (no point to keeping it equipped) the choker that has the run speed you want in its' title and you will get increased run speed for you and your companions, present and future. NPCs will be unaffected by the speed increase. Also, while sneaking or fighting, run speed will return to normal. There is also a choker to remove the perk. If you want to change your run speed in-game, just pick another choker.

I made this because I couldn't find a run speed mod that I liked. I didn't want to wear an item all the time to increase run speed, I just wanted something simple I could do once and forget about.

New in version 1.4:

Speed is reduced to normal during crippling limb damage to legs (optional)

New in version 1.31:

Fixed "always on" version.
Cleaned up general mod structure.
Fixed broken download link.

New in version 1.3:

Run speed now normal in combat
Added "always on" version.

New in version 1.2:

-Mod no longer increases sneak speed
-Scripting improvements mean it's no longer necessary to use the "remove perk" choker between speed changes.
-If my math is right, values should now be precise, not estimates.
-Added CrazyGoNuts speed. Careful, bumps in the terrain can launch you high in the air. Sneak speed is still increased for this mode.
-Added icons, FWIW (vanilla)


New in version 1.11:

Added 125% speed.

New in version 1.1:
-I changed the mod to use chokers instead of magazines because I couldn't get magazines to run a script on activate, it's easier to run a script on equip. Now instead of having 5 esp files there is one, only with 6 items, but run speed can be changed in-game.
-I also had a problem with the first version where sometimes new companions would run too fast, so I changed from a speed multiplier to a set value. Because of this, speed percentages are approximate.
-One other thing that was a little flaky in version 1.0, it seemed that sometimes new companions would not get the speed bonus. That seems to be fixed now.


Included speeds are:

125%
150%
200%
250%
275%
300%
CrazyGoNuts

Bugs:
Occasionally a speed change will fail to occur on start/end of combat. If this happens, go in and out of sneak mode to fix it. I'll maybe try using a different condition on the perk to try and fix it, if anyone has suggestions I would certainly like to hear them.
Occasionally a new companion will not get the perk. Re equip and un-equip the choker. Not sure how to fix this one, suggestions encouraged.

Special Thanks:
