In the early hours of Monday morning, Great Britain won their first gold medal at the Rio Olympics as Adam Peaty smashed his own world record in the 100m breaststroke.
Peaty, who had previously beaten his own world record in the heats, was firm favourite going into the final, and he didn't disappoint, finishing the race in 57.13 seconds.
The 21-year-old becomes the first Great Britain male swimmer to win an Olympic medal since Adrian Moorhouse, who won the same event in Seoul back in 1988.

After the race, Peaty admitted it was a surreal feeling to bring home Great Britain's first gold medal, saying: "It's so surreal to get Team GB's first gold.
"I came out tonight and took the first 50 easy and came back with everything I have got. I did it for my country and that means so much for me."
Peaty finished 1.5 seconds ahead of his nearest rival, but it wasn't just him that was stealing the show that night.
Thousands of miles away back in England, Adam Peaty's Grandma was enjoying her fair share of the spotlight as well.
A video has emerged of her watching her Grandson's 100m breaststroke final and celebrating after he claimed gold, highlighting the fact he's now won an Olympic gold, a Commonwealth gold, a European Championships gold, and a World Championships gold.
It's not just her video that's taken social media by storm, however. She's also been active on Twitter and has been interacting with her 5,441 followers.
