What's New in the Fourth Edition of The Triathlete's Training Bible?

Coach Joe Friel started writing the fourth edition of The Triathlete's Training Bible with a blank page: the entire book is new. The science and sport of triathlon have changed much since the previous edition released. This new edition adds emphasis to personalizing training plans, incorporates new power meter techniques for cycling and running, improves on the skill development techniques, updates the strength training approach, speeds recovery for busy athletes, and cuts through the noisy volume of training data to focus athletes on the numbers that mean the most to better performance. See Joe Friel's blog or VeloPress for an expanded summary of improvements to this fourth edition.
