TOKYO (Reuters) - An innocuous question from a friend set Sifan Hassan of the Netherlands on her quest for triple gold at the Olympics, she explained on Sunday as she headed home with two golds and a bronze.

The Ethiopian-born Dutch runner won the 5,000 and 10,000 metres, and finished third in the 1,500m, in a hectic programme at the Tokyo Games and said all she wanted to do afterwards was sleep.
