Limitations
Arthur Lydiard wrote that LSD system of training does not reach the levels of effort most effective for building aerobic fitness. Pete Pfitzinger has written that the long slow distance method of training is acceptable for novice runners hoping to complete a marathon, but that more experienced runners benefit from long runs that, depending on the workout, incorporate a variety of paces including speeds approaching race pace. According to Pfitzinger, varying paces are necessary because different physiological adaptations, including increased glycogen storage and fat utilization, occur at specific training paces.
Galloway points out that if a runner wishes to increase their speed, interval training or speed training is recommended. Henderson uses races as speedwork and is a proponent of speedwork in limited quantities.
The scientific literature indicates that high-intensity training can provide greater benefit towards anaerobic capacity than moderate-intensity endurance training. The U.S. Army is reducing the use of long runs in its physical training programs.

Famous quotes containing the word limitations:
“That all may be so, but when I begin to exercise that power I am not conscious of the power, but only of the limitations imposed on me.”
—William Howard Taft (1857–1930)
“To note an artist’s limitations is but to define his talent. A reporter can write equally well about everything that is presented to his view, but a creative writer can do his best only with what lies within the range and character of his deepest sympathies.”
—Willa Cather (1876–1947)
“Growing up means letting go of the dearest megalomaniacal dreams of our childhood. Growing up means knowing they can’t be fulfilled. Growing up means gaining the wisdom and skills to get what we want within the limitations imposed by reality—a reality which consists of diminished powers, restricted freedoms and, with the people we love, imperfect connections.”
—Judith Viorst (20th century)
