Hotels are sold out and thousands of spectators are expected as some of the world's top mountain bikers arrive in Blaenau Ffestiniog this weekend which sees the British Downhill Series get under way.

It's the first big event to be held at the town's new purpose-built mountain bike centre and there are sure to be plenty of spills and thrills, as Roger Pinney reports.
