We may see something big from Deena Kastor, the U.S. marathon and half marathon record holder, who headlines the Rock ‘n’ Roll Dallas Half Marathon this Sunday, March 23.
Deena turned 41 last month, and after a punishing World Champs marathon in Moscow last August she indicated that her days as an elite runner may be at or nearing an end.
The video above tells a different story. Taken by her husband Andrew Kastor, coach of the resurgent ASICS Mammoth Track Club, it shows Deena running comfortably at a 5:00 per mile clip. Behind her is Mammoth TC teammate Lauren Kleppin, who just ran a 2:28 at the Los Angeles Marathon, a 13-minute PR. We don’t know the context of this workout, but if Deena can drop a 2:28 marathoner in training, it bodes well for her to at least break the U.S. master’s record of 1:11:50 for the half marathon, which was set by Colleen De Reuck in 2006 at the Philly Half.
