Lance Armstrong cheated. He did so systematically, repeatedly and during each of his seven Tour de France championships. Armstrong admitted as much in an interview with Oprah Winfrey aired Thursday night, ending nearly a decade-and-a-half of lies, speculation and rumors about the cleanliness of his reign atop the cycling world.

But it was also easy to miss a few details while getting bogged down in the scope of Armstrong's wide-ranging admissions. The information was detailed—oftentimes overwhelmingly—and the takeaways from this session are enormous. With that in mind, let's take a look at a few of the biggest takeaways from part one of Oprah's interview with the disgraced cyclist.
