But 26, while she has faded in her losses, look at what she does in her wins! She closes hard and leaves everybody looking like they're going backward. Her first 200 is probably faster than her 2nd 200 (like pretty much everyone else in the world) but her 2nd 200 is very very strong, just like all Hart-trained athletes.
Remembering back to reading a Hart article a couple years ago, their early season training consists of repeat 200s on Mon, and an either Wed or Thur they're running 800s. He gives them a time goal for the first 400, and then they hang on for the last 400 as best they can. Over the course of the season, those 800s become 700, 600, 500, 450. Sanya's got some endurance there.
