In what looked like a scene straight out of a movie, Alysia Montano, 34 weeks pregnant with her first child, ran the 800 metres yesterday in the U.S. Track and Field Championships. The five-time national champion finished in 2 minutes, 32.13 seconds — nearly 35 seconds slower than her personal best of 1:57.34 in 2010 in Monaco.

An Associated Press report quoted her as saying after the qualifying heat: “I’ve been running throughout my pregnancy and I felt really, really good during the whole process.”

That the 28-year-old former University of California star finished last in her heat didn’t matter one bit to the crowd gathered at Hornet Stadium. Trailing the lead pack by more than 120 meters for most of the race, Montano received a rousing ovation as she finished her first lap and the cheering grew louder when she finally crossed the finish line.

“I just didn’t want to get lapped and be the first person to get lapped in the 800,” said Montano, the 800 national champion the past four years.

She was never close to being lapped, taking a nice relaxed pace from the start and maintaining it throughout.

That was according to the plan Montano laid out after consulting with her physician. Not only did doctors give Montano the OK to run, they encouraged her.

“That took away any fear of what the outside world might think about a woman running during her pregnancy,” Montano said. “What I found out mostly was that exercising during pregnancy is actually much better for the mom and the baby. … I did all the things I normally do … I just happened to be pregnant. This is my normal this year.”
