All In Running is, as its initials suggest, AIR -- and fresh air at that. It blows away hidebound expectations of a running program by focusing on far more than racing and increasing one's best timings. Air is all around us, and All In Running too focuses on the larger picture of our environs -- from what we eat to the terrain we run through -- making us not just better runners but also healthier, more ecologically attuned citizens of our world.
