What do you think is the best method of middle distance/distance training. I have found two major, conflicting methods. The first is Arthur Lydiard's training approach. He advocated building an aerobic base with longer, good aerobic effort runs (with occasional speedwork, and easy hill work), then moving into a hill phase(with 1 day a week long run, plus additional speedwork) an anearobic phase (with 1 long run a week, plus more speedwork),then a coordination and sharpening phase which cut down on the mileage and contained speedwork and fartlek runs. Lydiard's method has been used by Peter Snell, Murray Halberg, John Davies, Barry Magee and is used by many Kenyans today such as Nixon Kiprotich. The other training method is advocated by Peter Coe, Frank Horwill, and Bill Bowerman (produced runners like Sebastian Coe, and Steve Prefontaine) which is basically a combination of hills, interval work, speedwork, and fast tempo runs year round. They believe that longer, slower training makes longer, slower runners. Both methods have produced world class athletes that have broken world records, and won many olympic gold metals. I have seen sensible evidence from both sides supporting their methods. What do you think?
