Title: Clarke gives the formula for perfect balance in running
Review: A few decades ago, most runners undertrained. It wasn't until the 1960s that megamileage became common among distance runners. Now, the tendency is to overtrain, which leads to both physical and mental breakdown. Clarke's book is about achieving optimum balance between energy and effort. It's about coordinating the effort with the energy that allows for adaptation, i.e., better performances in the sport. Clarke offers a matrix in which workout effort is classified in varying degrees on one side and in which energy is classified across the bottom. There are 30 possible combinations of this effort-energy matrix. Clarke says that only five are optimum adaptive workouts.The runner who want to improve should gain a lot from reading Clarke's excellent work.
