Today marks just 50 days until the opening ceremony of the London 2012 Olympic Games.

To celebrate the occasion London 2012 has published a list of 50 ways to join in with the Games.

Ideas for London include getting your photo taken with the Olympic Countdown Clock in Trafalgar Square, watching Damon Albarn in his opera Dr Dee at the national Opera House as part of the London 2012 Festival, and sending a message of support to Team GB’s Olympic and Paralympic athletes via www.ourgreatestteam.com.

People are also encouraged to consider training to become a referee, official or coach in a sport that interests them, visit the giant Olympic Rings at St Pancras International Station, and view the Tate Britain’s exhibition of Olympic and Paralympic posters.

Seb Coe, chairman of the London Organising Committee of the Olympic and Paralympic Games (LOCOG), said: “The Jubilee celebrations and the incredible welcome given to the Olympic Torch Relay have shown the great community spirit of British people and their enthusiasm to get involved with big events.

“By releasing this list, we want to demonstrate that whatever your interests, there is a way for you to be part of London 2012. We are urging the UK public to join in, and to keep their bunting and flags ready to mark what will be an unrivalled summer of sport, culture and celebration.”

London 2012 is also encouraging people to become a Local Leader - a person in the community who organises events to celebrate the Games.

There are currently more than 14,000 Local Leaders across the country for London 2012 who have already hosted or are planning events.

The Mayor of London Boris Johnson said: “With a mere 50 days to go, we are keeping our foot on the pedal to make sure everything is in place for a smooth and successful Games. We will learn any lessons from the spectacular celebrations of the Diamond Jubilee and will make sure the capital is buzzing as we roll out a huge programme of events and festivities for everyone to enjoy.

“So whether it’s watching the sporting spectacle at our live sites or being inspired to take up a new sport, joining in the free arts extravaganzas going on across the city or just enjoying the shopping, theatre and restaurants that make this the best big city in world, London is the place to be.”
