Adam Peaty has claimed Team GB's first medal of the 2016 Olympic Games after winning gold in the men's 100m breaststroke final.
Having dominated the heats and semi-finals, the 21-year-old claimed the win in the final with a new world record mark of 57.13 seconds, beating his own time set in the heats just yesterday.
As the world number one, the man from Uttoxeter was always expected to win the race, and he duly converted his dominance to finally put Great Britain onto the Olympic medal table.
In the process of winning, Peaty becomes the first British man to win an Olympic gold in the pool since the 1988 Games in Seoul, when Adrian Moorhouse topped the podium in the same event in which Peaty has this evening 28 years later.
Peaty storms field to claim Olympic gold
Ever since shooting to prevalance in 2015 after winning three gold medals at the World Championships, Peaty has been earmarked as a British swimming superstar.
The World, Commonwealth, European and now Olympic champion in this discipline stormed the field and never looked like being defeated from the moment he took the lead 15 metres out.
Turning with a lead of 0.6 of a second, Peaty extended his lead over the final 50 metres, smashing the world record he had set on Saturday.
His main rival, Cameron Van Der Burgh of South Africa finished in second, with America's Cody Miller third, both more than a second behind the Brit.
"I did it for my country" said Peaty in his post-race interview for the BBC, and his nation will wake to news of a new Olympic champion.
Team GB finally on the board
Having come close to medalling on a number of occassions, Team GB finally have their first medal of the Rio Olympics.
Both cycling road races came and went without success, while Hannah Miley (swimming) and Richard Kruse (Fencing) fell agonisingly short in their medal chases having finished fourth.
With a medal target of 48 set before the games, it has been a slow start for the Brits, but the same could be said for the early days back in London four years ago and that ended up brining astonishing success to the nation.
