BERLIN (AP) Natalie Charlos of Poland was rescued unconscious from the water during the women's 10-kilometer race at the start of the European swimming championship on Wednesday.
Alerted by officials and spectators, a lifeguard pulled Charlos ashore, where she was revived.
Charlos was recovering well after overexerting herself, Germany team doctor Alexander Beck said.
Charlos, who lives and trains in Germany, picked the wrong lane as she approached the finish area.
Sharon van Rouwendaal of the Netherlands won the open water event. Eva Risztov of Hungary took the silver, and Aurora Ponsele of Italy the bronze.
Daniel Fogg of Britain won the men's five-kilometer race, ahead of two Germans, Rob Muffels and Thomas Lurz, respectively.
