Query: Great book

Joe Friel did a great job at creating a book with information needed for the cyclist looking to step up their yearly training program. It includes everything from some of the basic physiology knowledge of metabolic pathways to goal setting, proper nutrition before/during/after event, and even the training and off-season. I am in my mid-20's with little thought of the aged cyclists, but he takes into account the young 10/12 year old cyclists, my age, and the 40+ training program. He gave me knowledge and a base to create my own yearly training program, prioritizing my A, B, and C events. Within this yearly scope, there are workouts suggested for each week and tests to measure the training progress. The knowledge is great and gives the reader knowledge to create their own personal plan. A great book and must-have for any cyclists interested in becoming more competitive.
