Allyson Felix runs final competitive race

The big picture: "To be able to finish here tonight, with Cami in the stands, and to share that moment with her, it means a lot," said Felix after hanging her medal around her 3-year-old daughter's neck.

• The once-shy Felix has found her voice in recent years, and much of that stems from becoming a mother to Camryn, who she calls her "greatest accomplishment."
• The L.A. native had a life-threatening birth experience, then made waves when she left Nike after the company wanted to pay her 70% less than before.

The last word: "I felt joy running tonight," said Felix, unveiling an inner peace that all athletes seek at the end.
