800 meters and 8 months pregnant? Dr. Sanjay Gupta on the risks of racing at 32 weeks

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.
