Do you run faster with weapon holstered?

[PieParadox]

I hear yes but I personally can't see much difference

[WaltF4]

The running speed reduction for holding a weapon is related to the weight and length of the weapons in question. Longer and heavier weapons will slow you down more than shorter and lighter weapons would. I have a post that includes speed measurements while holding weapons of different weights and lengths.

Wow thanks for the always good and detailed information Walt

thx i wanted to know it too

For clarification besides what WaltF4 said (who is a massive bank of knowledge for this game), you do not however gain any speed when putting a shield on your back.

According to this thread on taleworlds, the running speed reduction is also influenced by your weapons speed: http://forums.taleworlds.com/index.php/topic,118906.msg2872758.html#msg2872758

Its a little further down, one of the posts made by Stabbing Hobo.

Myth #5
Only the weight of the weapon you're holding slows your movement speed

There is a slowdown for holding weapons, but I discovered it's not only about the weight of the weapon, it's also about its speed lenght.
*Notes:
     -I'm talking about movement speed, not attacking speeds here.
     -There doesn't seem to be penalty for speeds of 100 and above. (I haven't tested whether there's still the weight penalty for holding it. To be tested)
     -Daegoth stated that the speed influence is now removed. Instead, weapon lenght should have an effect (Probably had before as well)
