Between now and the beginning of the Olympic and Paralympic Games, London 2012 will run a number of test events at all of its venues.
The London 2012 test events, called London Prepares, will include the first competitive sports to take place in the Olympic Park.
The events will test the sporting field of play; results, timing and scoring systems; how London 2012 teams work together and how people move around venues.
Below is a list of some of the test events already announced. There’ll be more to come, so check this page again in future to keep up-to-date.
