QUOTES OF THE DAY

"Before my race, I ripped my swimsuit and I had to ask my coach whether I should change it. I was trying to pull up my costume and my nail dug into the costume and went through it. So I had to change to a different suit," - Nepal's Gaurika Singh, the youngest competitor in Rio at just 13 years old, had a little wardrobe malfunction before winning her 100m backstroke heat.
"I absolutely support it. We definitely, definitely shouldn't be racing in these conditions," - British Rowing performance director David Tanner gave his full backing to the decision to cancel Sunday's rowing events.
SINGH'S QUAKE SURVIVAL STORY

But the youngster has an even more compelling story to tell, having been a survivor of the 2015 earthquake in Nepal.
She said: "I felt so grateful that I was one who survived that whole earthquake, so just to be here to make my country proud is great. I was in a five-storey building when the earthquake struck."
