At the London 2012 Olympics, which sport took place in the building nicknamed "The Pringle"?

Lee Valley VeloPark is a cycling centre on Queen Elizabeth Olympic Park in Stratford, East London. It is owned and managed by Lee Valley Regional Park Authority, and it was opened to the public in March 2014. The facility was one of the permanent venues for the 2012 Olympic and Paralympic Games.

In 2009, work began on the construction of the velodrome. The estimated cost of that facility alone was £105 million. Work on the velodrome was completed in February 2011 and was the first Olympic Park venue to be completed. The roof is designed to reflect the geometry of cycling as well as being lightweight and efficient reflecting a bike. The velodrome was officially opened by many successful British athletes including Chris Hoy and Victoria Pendleton. It is informally known as "The Pringle" due to its distinctive shape.

There is also a 360-degree concourse level with windows allowing people views of the Olympic Park. The velodrome is energy efficient—roof-lights reduce the need for artificial lights, and natural ventilation reduces the need for air condition. Rainwater is also collected, which reduces the amount of water used from the municipal water system. Designer Ron Webb, who designed the velodrome tracks for the Sydney and Athens Games, was in charge of the design and installation of the track.
