In this book we find a review of Roger Roca's vital and sportive work, a world championship of duathlon.
The tracta d'una visió franca i emotiva que ens deixa entrar en la persona que hi ha darrere l'athlete, per experimentar com es gesta una vida dedicada a l'esport.
In the course of the process that it has been proclaimed to be a champion of the world of duatló, i ens afegeix a 10 km course of study, from mitja marató i de marató perquè també puguem reeixir en la pràctica esportiva.
For the author, sport has been his school of life and he has become the person he is.
He has had some successes but he has also had to evolve and learn from the difficulties, mistakes, failures and renunciations: "I have not been more of a super gifted person.
My success in work, in effort, in discipline and in the constancy of my purposes, may be better than in the constancy of my acts".
