PITTSBURGH (AP) -- A Tennessee woman has begun a 981-mile swim of the length of the Ohio River.
Mimi Hughes plunged into the river on Saturday in Pittsburgh and plans to swim about eight hours a day for 60 days until she reaches Cairo, Ill.
The marathon swim is aimed at raising money for groups working to improve education for women and girls.
There are more than 30 dams along the route, which she and the various kayakers assisting her will have to walk around. The 54-year-old mother of four from Taft, Tenn., is wearing a wet suit in the 60-degree water.
In 2006, she swam the Danube, Europe's second longest river after the Volga. She also swam two smaller rivers in Europe and the frigid Bering Strait between Alaska and Russia.
