Genzebe Dibaba's breathtaking world record performance and to a lesser extent, Shannon Rowbury's American record last week in Monaco were landmark events. Since Dibaba has been training to focus on the 5000, there is a lot of speculation on how fast she can ultimately run the distance.
It's been a big week for American distance athletes, with two American records and several other significant performances. In a year with no World Championships or Olympics, it's an exciting opportunity for athletes to push their limits to achieve some of the fastest times in history. They're inspiring to us mere mortals, and to future running stars.
