Five-part docuseries on the world of sports. Olympian Caitlyn Jenner reflects on her journey to winning gold.

After a failed attempt in 1972, Caitlyn Jenner made it her mission to win decathlon gold in Montreal in 1976. Training every day for four straight years, she turned herself into the odds-on favorite. But for Jenner, the 1976 Olympic decathlon was more than an athletic test. It was a welcome distraction from the far more challenging inner turmoil of coming into her own identity.
