Pacing strategy

A pacing strategy is the way an athlete distributes effort and speed over the course of a race. It shapes how energy is used and how performance responds to terrain, distance, and competition.

Even pacing: A strategy that keeps speed or effort approximately constant throughout a race. It is the benchmark against which other ways of distributing race effort are compared.
Marathon: A road-running race covering 42.195 kilometers. Its duration makes early restraint and late-race fatigue central pacing concerns.
Surge pacing: A strategy that deliberately alternates faster surges with slower recovery periods. It contrasts with steady pacing by using repeated changes of speed to gain position or disrupt rivals.
Aerobic threshold: An exercise intensity below which lactate production and removal remain relatively balanced. It describes a boundary relevant to sustainable effort during prolonged races.
Negative split: A pacing pattern in which the second half of a race is faster than the first. It reserves capacity early so effort can rise later.
Middle-distance running: Track races from 800 to 3,000 meters, demanding both speed and endurance. Tactical positioning and changing speed matter alongside physiological limits.
All-out effort: An attempt to exert maximal effort from the start, without reserving capacity for later. It marks the extreme alternative to pacing effort across the full race.
Lactate threshold: The exercise intensity above which blood lactate rises more rapidly than it can be cleared. Crossing it for too long can make a planned pace unsustainable.
Positive split: A pacing pattern in which the first half of a race is faster than the second. It can result when early effort exceeds sustainable capacity.
Cycling time trial: A cycling race in which riders compete individually against the clock. Without a pack to follow, riders must regulate effort across changing course demands.
