It's no wonder Christine Ohuruogu is smiling... She's one of the British medal winners who are helping Team GB to have their most successful Olympics for years.
When Scotland's Chris Hoy won the men's sprint, he became the first Briton to win three gold medals at the same Games for 100 years!
And 19-year-old Louis Smith is the first British male to win a medal in an individual event in the gymnastics for 80 years! He got a bronze medal for his routine on the pommel horse.
This is the moment Rebecca Adlington realised she'd not only won her second gold of the Games, but had also broken the world record for the 800m freestyle. Congratulations!
Nicole Cooke won Team GB's first gold medal in Beijing, in the women's road race, and fellow cyclists Rebecca Romero and Victoria Pendleton have struck gold too.
Mark Hunter and Zac Purchase crossed the finish line first in the lightweight double skull, winning Team GB's first Olympic medal in the event. Well done to them for making it a gold!
Team GB are doing really well in the water this year - Iain Percy and Andrew Simpson scooped Britain's 17th gold of the Games in the Star class event.
And it was gold for sailor Ben Ainslie in the Finn class too. The win means Ben has now won gold in three Olympics in a row, making him Britain's most successful sailing champion ever!
