Movement Speed determines how fast your character can move from one hex to the next.
The value displayed on your in-game character page ("C" by default), "Run Speed," is your true movement speed % (relative to base), called "effective speed" in the tables. It shows the combined effect of all the movement speed modifiers that currently affect you. The default base value is 100, but various movement speed bonuses make it possible to increase it all the way up to 250, which is 2.5x the speed your character could move at in the original Fallout games.

- The Bruiser trait significantly reduces your movement speed.
The underlying variable
Under the hood, the game uses an internal value called the Run Time Stat (ST_RUN_TIME) to calculate movement. Lower Run Time Stat = faster movement (the less time it takes you to run from A to B, the faster you are). Its base value is 200, which corresponds to the effective speed of 100%.

Run Time Stat = 200 - 2 x Movement Speed Bonus
- Every 0.5 kg over your weight limit increases your Run Time Stat by 1, which decreases your movement speed bonus by 0.5 percentage points. Movement becomes impossible when your Run Time Stat reaches 1000 (Effective Speed ≈ 20%).
- Endurance increases the Run Time Stat by 0.5 per point. This results in a decrease of 0.25 percentage points in movement speed bonus.
Effective Speed = 20000/ST_RUN_TIME
- Each percentage point of movement speed bonus reduces your Run Time Stat by 2, which yields progressively larger gains to your effective movement speed; conversely, you lose less and less effective movement speed with every consecutive movement speed penalty.
