" This great attitude is one that every endurance athlete should emulate. The only way to determine your optimal racing weight is to discover it through experience, and the only way to attain your optimal racing weight is to focus on performance. If you eat and train for maximum performance, you will ultimately achieve your best performance, and your weight and body-fat percentage on that day will define your optimal racing weight. In the meantime, be patient and enjoy the mental challenge of trying to figure it all out. "
