Mountain biker flies through mall

Each year a group of professional mountain bike riders swap the great outdoors for the confines of a multi-storey shopping mall in Prague.

Forget negotiating trees and rocks on your decent to the finish line, these guys have escalators and shoppers to deal with as they compete for the fastest time to the bottom.

There's a narrow track marked out for the speedsters, but the route is lined with curious shoppers who are just one wipe-out away from being...wiped out.

There are also jumps and other obstacles thrown in for good measure to make sure it's not too easy.

Tomas Slavik won the event for the third year in a row.
