Pace - The most economical distribution of effort The most economical distribution of effort over a distance, whether running, swimming, cycling or rowing, is obtained by performing at a constant rate over the entire distance. Acceleration and deceleration are costly and too expensive to employ as deceptive tactics. The racing distance is covered in the shortest time when the total available energy is distributed evenly over the distance. The achievement of proper pace requires extensive training. Pace training may be facilitated by the use of a pacing machine so that the athlete follows a marker which is traveling at a fixed rate. The rate is increased as skill and condition are improved until the plateau of maximum training is reached. The athlete then trains with the pacing machine set at his best (competitive) speed. Well-trained athletes have found this system useful in establishing a pace for an unaccustomed distance. The pacer can be set at a record-breaking rate if the athlete desires to train for setting a new record. The rate necessary to defeat a known opponent may be used to train for this objective. An inexperienced athlete may lower his own record in an event by using the pacing device set to cover the distance at a steady rate and in slightly less time than the athlete's previous record. A study of the split times of distance races of champions reveals that their rates are steady. An unsteady rate characterizes the novice. The ability of the athlete to judge his speed is an important objective of a training program. Many experienced runners carry a stopwatch for this purpose and swimmers have the times at each lap called out by an assistant.
