Tokyo 2021 has officially begun after the Olympic cauldron was lit during last night's opening ceremony.
There's no hanging around for the Team GB athletes, many of whom get their Olympic campaigns underway today.
With 67 medals won in Rio, the British team smashed their target, however this year there is no specific medal goal, due to the difficult circumstances preparing for the games.
It's set to be an action packed fortnight of sport, filled with highs and lows.
Here are all the events taking place today, and all the Team GB athletes to look out for...
