The Power Meter Handbook: A User’s Guide for Cyclists and Triathletes

of all he has done for power-based training in such a short time.
    There are many others who have contributed to this book’s development from an outline to what you now hold in your hands. A heartfelt “thank you” goes out to all of the following.
    Hunter Allen for his and Dr. Coggan’s book, Training and Racing with a Power Meter, which initially guided me through most of the details of power-based training and which I highly recommend to all cyclists. Theirs is by far the most comprehensive description of the topic.
    Bill Cofer, my friend of 41 years and occasional training partner, for offering enthusiastic and detailed help with an explanation of the physics of power in Chapter 2 and his suggestions for Chapter 10 .
    Ted Costantino, publisher of VeloPress, for providing guidance on the many issues I faced in writing this, for keeping me on track throughout thewriting process, and for solving my many challenges in explaining complex concepts.
    Exercise physiologist Alan Couzens for his input on speed relative to power in pacing with his 50-40-30-20-10 Rule.
    Gear Fisher, the CEO of Peaksware, LLC, for assisting with power analysis software terminology.
    Dirk Friel, my son, for reviewing software graphics and for helping on the sections dealing with handlebar computers.
    Justin Henkel, the director of education for Saris, for suggesting this book and helping to define its purpose.
    Renee Jardine of VeloPress for giving the book its initial form, voice, and focus and for continuing to support my ideas for book projects.
    Uli Schoberer, the inventor of the first mobile power meter and the owner of SRM, for lending me a power meter to try in 1995 and thus initiating my interest in power-based training.
    Finally, I want to thank Joyce, my supportive and loving wife of 46 years, for encouraging and assisting with my sometimes quirky ideas. She continues to be there for me despite my 4:00 a.m. wake-ups as I study and write about things that interest me.
