Hunter Allen, Dr. Andrew Coggan, and Dr. Stephen McGregor explain the key aspects of watt-controlled training in this book. They introduce various watt measurement systems and analysis programs for ambitious cyclists of all performance levels and explain how to optimize training with them. By using performance and fatigue profiles, each rider can identify their individual strengths and weaknesses and train accordingly. Numerous training plans for various demands and needs allow for a direct implementation of theory into practice. Cyclists and coaches from different disciplines—ranging from road, track, mountain bike, or BMX riders to triathletes—will find in this book a scientifically grounded guide for using watt measurement devices in training and achieving long-term performance improvements. The authors have many years of experience as professional coaches and are among the world's leading experts in the field of watt-controlled training. They excel at presenting theoretical knowledge in a practical and easily understandable manner.
