Seb Coe, the Chairman of the London Organising Committee for the 2012 Olympic Games, stands in the middle of the newly completed velodrome, as he is passed by cyclists led by British track stars Victoria Pendleton, front left, and Sir Chris Hoy, right, at the Olympic park in London, Tuesday, Feb. 22, 2011.

Building work began on in March 2009 and it took a team of 26 carpenters eight weeks to install the track and more than 350,000 nails were used on its 34 miles of timber surface.
