Whether you’re just starting or a seasoned pro, Joe Friel will help you train smarter in all three disciplines and school you in proper fueling in “The Triathlete’s Training Bible.” If it ain’t on your bookshelf, you can’t really call yourself a triathlete.

This fourth edition of the “The Triathlete’s Training Bible” incorporates tech that’s now available (somewhat affordably) to the masses, like power meters, new strength training and recovery science–especially for time-crunched athletes (isn’t that all of us?)–and explains the numbers you should and shouldn’t be paying attention to. What’s more important: Heart rate? Heart rate variability? Weight? Grab your Bible and find out.
