Burn: A Balance of Fitness and Fun. Sometimes a book title can mislead. Especially this title with its illustration, in which the scale seems to be heavily tipped to the “fun” side. The truth is that following the program in this book will require lots of training and little fun—until you reach the last two chapters. At that point, all your hard work and effort will begin to pay off. Your level of fitness will allow you to enjoy the day and your surroundings as you glide along your favorite trail. Maybe you will even be able to relish a little competition on the weekend, followed by a couple of cold beers with friends after the race. At that point, the reward will far outweigh the effort.
