THE deputy headteacher of Wellington Prep School and her husband are set to take part in the Tough Mudder Challenge.

Catherine Aish and her husband Tom are taking on the challenge next month to raise £500 for Arthritis UK.

The couple will be battling against 500,000 litres of mud, 40 tonnes of ice, thousands of gallons of water and electric shocks while tackling a 12-mile run and 20 obstacles.
