Running (GURPS) is one of Fallout GURPS skills. See: Fallout GURPS.
This skill is based on HT, not DX. It represents training in sprints and long-distance running. If you have studied this skill, divide your skill level by 8 (don't round down) and add the result to your Speed for the purpose of calculating your Move score (this affects land movement only).”— Steve Jackson Games GURPS sources
With the abandonment of GURPS, Running (GURPS) was removed from the game
