Today marks the start of the action in the London 2012 Olympic Velodrome which is nicknamed The Pringle.
The velodrome has been a happy hunting ground at recent Olympics for Team GB.
The 6,000-seat London 2012 Olympic velodrome cost £93m and took 23 months to build. It featured design input from Team GB cycling legend Sir Chris Hoy.
The Velodrome is one of the most sustainable venues in the Olympic Park. Its roof deflects the sun to reduce the need for air conditioning, and collects rainwater to cut mains water usage by 70%
The cable-net roof is made from 10 miles of steel cables - more than twice the height of Mount Everest.
It took a team of 26 carpenters eight weeks to install the Siberian pine track and more than 350,000 nails were used on its 35 miles of timber surface.
After the Olympic Games, the venue will be handed over to the Lee Valley Regional Park Authority and form the heart of a new VeloPark for use by the local community, clubs and elite athletes.
The VeloPark will also include the reconfigured BMX track, a new mountain bike track and a new road cycle circuit.
