Last month we reviewed Run Right Now, a new book by Joe Henderson. While this is not a regular book review column, we're very excited about another new running book this month and could not wait to tell you about it, Daniels' Running Formula is a very different book from anything put out by Joe Henderson, just as Formula's author, Jack Daniels, has an approach to running that is totally different than Joe's. Although both love running and want to help and support runners.

Jack is an accomplished coach of serious distance runners and had unmatched credentials among American coaches. His approach is highly detailed and scientific, and completely geared to giving readers the plan for achieving goals in competition. Daniels has been studying running physiology for many years and has data to empirical back up every plan. He also has hands-on coaching experience aplenty, and this unusual combination pays off for the reader who is able to discipline him or herself to follow Daniels' formulas.

Readers can choose from four programs laid out in detail in Daniels' Running Formula: red, white, blue and gold programs to get into shape, target a race, or regain conditioning after layoff or injury. Daniels does not spare detail in telling the hows and whys of his programs, he shares some -probably just a mall amount -- of the immense amount of knowledge he had gained in his years in the sport. You can just jump right to the workouts and assume, rightfully, that Daniels knows what he is talking about, but we find it fascinating to read through the text of this 284-page book and learn more about stride rate, lactate thresholds, VDOT testing, VO2 max, and more.

Don't let this review of Daniels' Running Formula scare you off if you are "just" a casual runner or shy away from the technical of running. This is well-written book with plenty of examples from contemporary runners that anyone should find interesting.

As for Joe Henderson's work? As we said in last months review, great writing, a wonderful love of running, and plenty of real- world low-key inspiration to keep you going. Both books are great and there are plenty of runners who will benefit from each, Probably not at the same time, though.
