Karen Moras

Karen Lynne Moras (born 6 January 1954), also known by her married name Karen Stephenson, is an Australian distance freestyle swimmer of the 1960s and 1970s who won a bronze medal in the 400-metre freestyle at the 1968 Summer Olympics. Although she set multiple world records she peaked between Olympics and was unable to capture gold at Olympic level.

Trained by Forbes Carlile, and making her international debut as a 14-year-old prodigy, Moras was expected to win medals at the 1968 Mexico City Olympics. She struggled, however, to adapt to the rarefied air at high altitude conditions and required medical treatment for breathing difficulties and hyperventilation. Despite this Moras managed to salvage a bronze medal in the 400-metre freestyle, behind the American duo of Debbie Meyer and Linda Gustavson. She nearly claimed a second bronze in the 800-metre freestyle, being beaten into fourth by 0.1 of a second by Mexico's Maria Teresa Ramírez who was much more acclimated to the local conditions.
