From here to insanity -- Confronting the greatest obstacle: your will -- Overcoming obstacles, tossing your cookies -- Changing your frame of reference -- Getting spartan fit -- Change your diet, change your life -- Moving past mountains -- Making your limits vanish -- Transformance: forging new bonds -- The finish line: becoming spartan.

Obstacle course racing, which combines the endurance challenges of a marathon with the mind-bending rigours of overcoming obstacles along the way, is taking the world by storm. At the centre of this phenomenon is Joe De Sena, the driving force behind the enormously popular Spartan Race. De Sena offers a simple philosophy: commit to a goal, put in the work, and get it done. From that philosophy, as played out first in his own life and now for millions across trails, through mud, and up mountainsides, Spartan Race was born. Now De Sena gives you a life strategy guide that takes you out of your comfort zone and into a combat zone.
