Optimizing race speed performance is not as difficult as you think. Athletes and coaches today want quick results, and while we do not agree with this practice, we'll show you how scientific knowledge can help you improve your personal best. Running is sweat, sacrifice, commitment and a lot of dedication. But also movement, life, color and reason for expectations that often can not be expressed in the desire to be better every day. This work was written for coaches at any stage of their career, athletes and sports lovers, who want to understand the task of being faster on the slopes. It has also been structured to assist students in sports science, especially those with knowledge in training. It presents the determining factors for success in preparing sprinters, a reflection on the passionate way we engage in the task of pursuing well-defined goals. How to be fast synthesizes a decade of effort in preparing sprinters. We wish to raise the aspiration to overcome your limits in this journey that awakens loves and hatreds, but which, in fact, has one of the greatest potentialities, to be faster!
