Lance Armstrong is retiring again and this time for good.

Almost a month after finishing 65th in his last competitive race in Australia, and nearly six years removed from the last of an unprecedented seven straight Tour de France titles, the 39-year-old cyclist made clear there is no reset button this time.

His retirement ends a comeback effort that failed to produce an eighth title or diminish talk that performance-enhancing drugs helped his career. The timing has as much to do with his growing responsibilities and family as it does with the physical limitations time has imposed. He’s tired, and tired of being hounded.
