Running 800 meters is tough enough. But doing so while eight months pregnant? Such was the goal of Alysia Montaño, a five-time national champion who took to the track Thursday for the US Track and Field Championships in California.
Though Montaño's time of 2:32 landed her in dead last, the pace was roughly equivalent to a very impressive five minute mile. But while extraordinary, was such an ambition safe for the unborn baby and the soon to be first-time mother?
On Friday night Anderson Cooper asked Dr. Sanjay Gupta for his professional analysis and conclusions.
Watch the above video as the CNN Chief Medical Correspondent explains why the half mile race may have been okay for Montaño, but not necessarily everyone else.
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
