Miller, the 22-year-old from the Bahamas, stayed even with Felix for 398 meters, then sprawled, dove and crashed across the line to edge Felix by .07 seconds. She’ll get the gold medal in the 400 meters. Maybe they should give her a cape, too. Starting from Lane 7, Miller expanded the lag, instead of getting gobbled up. Felix slowly chipped away.

They came down the last 100 meters and Felix drew even, maybe even got a step ahead. It took a head-first dive by Shaunae Miller at the finish line to beat Allyson Felix, denying her a record fifth Olympic gold medal. Suddenly, the quest for two golds was simply a struggle to make the Olympics. She did in the 400.

But the 200, which requires more “speed work” running hard around the curve, never got where it needed to go. She was one of those rare athletes who had the cachet to get the Olympics to change the schedule. After winning the world championship at 400 meters last year, she put the 200-400 double in her sights for the Olympics.
