Negative Split Running
Negative split running finishes the second half faster than the first, sparing glycogen when the start stays controlled. It is a hallmark of disciplined marathon pacing.
Negative split running means completing the second half of a run or race faster than the first—common in well-paced marathons and tempo workouts. It conserves glycogen and limits early lactate buildup when the opening miles stay controlled.
Practice negative splits on long runs with the final 20–30% at steady marathon effort.
