Test your mettle as a popular mud run returns to Eastnor Castle.

The Eastnor Mud Bath three kilometre mini, six kilometre and 10 kilometre races, as well as mud-free races, will take place on Saturday and Sunday (April 27-28) from 10am.

The Castle's tough, muddy trails, usually the training ground for Land Rover vehicles, will challenge participants with its natural obstacles and hills.

On the day registrations are guaranteed to be available, but the online registration has closed.

The Saturday will include mud-free races under the Eastnor Backyard and Relay races, with the Eastnor Castle Mud Bath on Sunday.
