We spent the day at Hadleigh Farm, home of the Olympic mountain bike course to check out the updated track, which is, according to London 2012 officials, "higher, wider and harder" than the trail used for last year's test event. Here's our behind-the-scenes photo gallery.

The 4.7km track, built on land on by the Salvation Army, is complete but remains closed to the public. After the Olympic Games the course will be converted to a red trail to form part of a wider cycling network. Read more about that here.

Annie Last was also present but walked the course, instead opting to get in some road miles on a bike which is part of Boardman's B56 project.
