The Olympic Delivery Authority (ODA) has unveiled the completed London 2012 Olympic Velodrome – the first venue to be handed over.

The Velodrome – which will host the cycling and BMX events during the Games – was completed on time and on schedule.

Team GB cyclists - including Sir Chris Hoy and Victoria Pendleton – were on hand to take a look at the track, which organisers are branding the fastest ever.

Chris Hoy, triple Gold medal-winner at the Beijing Games and the most successful Olympic male cyclist of all time, said: “Having been involved in a very small way in the design process in the early stages, it is amazing to see the Velodrome finally completed.

“To be able to have ridden on it today gives me a feel for what it is going to be like in less than 18 months time.

“I cannot wait!”

After the Games, the Velodrome will be used by elite athletes and the local community and will include a café, bicycle hire and cycle workshop facilities.

Hoy and Pendleton were joined Jason Kenny and Ross Edgar, together with rising stars and established names in the GB cycling team for the opening.

ODA Chairman John Armitt said: “In delivering the Velodrome on time and to budget, we have completed our first Olympic Park venue and biggest milestone to date.

”The striking architecture of the Velodrome and the medal prospects of our world-leading cyclists mean the venue will become one of the defining images from the Games, and a landmark new building for future generations to enjoy.”
