Planning your training schedule for high school and college running is a daunting task, whether you are a coach or a young runner yourself. What should your weekly workouts look like? How much mileage should you run? How do you ensure that you are on the right track for long-term development? Modern Training and Physiology for Middle and Long-Distance Runners answers these questions and many others. It is a short but detailed explanation of the practical aspects of exercise physiology and modern coaching, including energy systems, the aerobic and anaerobic thresholds, VO₂ max, running economy, muscle fibers, and more. In addition, it covers how these ideas inform both your day-to-day workouts and the underlying philosophy that forms the foundation of your training program. To become a better runner, you need to apply your own knowledge of training principles, tailoring your workouts to improve your strengths, bolster your weaknesses, and ultimately take your racing to new heights.
