<DIV><DIV>In only a few short years, power meters have become an essential training tool for amateur and pro cyclists and triathletes. The first edition of Training and Racing with a Power Meter was largely responsible for popularizing what was once an arcane technology understood by only a few elite coaches and trainers. Now the updated and revised second edition provides significant updates on technology, software tools, training protocols, and workouts, making the benefits of power-based training available to everyone. The new edition also includes specific information for triathletes&#8212;the fastest-growing segment in endurance sports&#8212;including a complete triathlon training plan. Other significant updates include reviews of the latest hardware, refinements and additions to training plans, additional case studies, more on monitoring fitness and chronic training loads, and revised and clarified artwork, charts and tables throughout. Training and Racing with a Power Meter, 2nd Ed., will continue to be the definitive guide to the most important training tool ever developed for endurance sports.</DIV>
