Who won the inaugural Women's Olympic Marathon in 1984?

In March 1984, Benoit injured her knee severely during a 20-mile training run, forcing her to undergo arthroscopic knee surgery just 17 days before the United States Olympic Women's Marathon Trials were scheduled. However, she recovered from the surgery much quicker than expected, and showed up at the trials as the woman to beat. She beat runner-up Julie Brown by 30 seconds, winning in 2:31:04. Three months later, she competed in the 1984 Summer Olympics in Los Angeles and won the first Olympic Women's Marathon in 2:24:52, several hundred meters ahead of Grete Waitz, Rosa Mota, and Ingrid Kristiansen, all considered legends in their own rights.
