Cheese rolling returns to Coopers Hill
Thousands of people are expected in Gloucestershire for one of the county's most famous traditions.
The annual cheese rolling at Brockworth will see men and women chase wheel-shaped Double Gloucesters down Cooper's Hill. Surprisingly, few of them end up with injuries.
The races attract competitors - and spectators - from all over the world.

The tradition of chasing a cheese down the 200-yard hill dates back to the early 1800s.
The event became so popular, with around 15,000 spectators lining the course in 2009 that organisers were forced to cancel the next year and it now continues in an unofficial capacity.
Gloucestershire Police are concerned about the numbers that might turn up to what is now a global phenomenon. The force has issued the following statement to those who plan to go along.
The first race gets underway at noon.
