Answer
Sonia O'Sullivan, an Irish athlete, achieved similar feats as Tirunesh Dibaba by claiming world championship crowns in both short (5000m) and long (10,000m) distance running events. O'Sullivan's triumphs occurred during the 1990s, with her 5000m success in Gothenburg 1995 followed by her 10,000m victory in Athens 1997. She became the first woman to complete this double and remains one of the few to have accomplished it.
