Coach Vigil was a hard-data freak, but as he watched Ann plunge into the Rockies with her ballsy do-or-die game plan, he loved the fact that ultrarunning had no science, no playbook, no training manual, no conventional wisdom. That kind of freewheeling self-invention is where big breakthroughs come from, as Vigil knew (and Columbus, the Beatles, and Bill Gates would happily agree).
