There are just 100 days left until the Olympic games.
To mark the countdown there will be events held across the Midlands.
The Ricoh Arena in Coventry, which is hosting the Olympic football matches, will change its name temporarily to the City of Coventry stadium.
In Leicester, students from across the city will be taking part in sports activities.
It's hoped these events will encourage children to take an active part in the games and will help to create a strong legacy in the city.
The 2012 Games Legacy Director is looking forward to celebrating this key milestone:
– Shimul Haider, Games Legacy Director for Leicester
"Today is an opportunity to get as many people as possible to be enthused by the upcoming Games and have them take part in some form of sport and physical activity. We want to create a strong legacy from the Games for the local area, and part of today will also be about encouraging everyone to make a pledge for 2012 - perhaps to try a new sport or get fitter".
In Birmingham, one hundred sports volunteers will gather in Victoria Square, where they will create a large 100 symbol to mark the countdown.
Birmingham will be hosting both the Jamaican and USA track and field team ahead of the Olympics.
Birmingham City Council is also launching its Olympic website which will contain the full programme of activities taking place in the city.
