Great book
This book essentially eliminates wasted training in favor of higher intensity, shorter and less frequent workouts. A shorter high intensity work out is the best way to improve actual performance and doing the "junk miles" or LSD just wastes time and energy. This allows more time for recovery and focuses your training time on the developing the speed and intensity you will use in racing. Makes a lot of sense and I'm integrating it in my training plans with good success. I liked his statement that a "recovery run" is an oxymoron - go for a bike ride or swim instead. A very worthwhile book for anyone serious about improving with increased efficiency.
