A team at Sheffield law firm Nabarro discovered supporting your favourite charity can be a dirty business.
Staff faced a 10k 40-obstacle course of hills, mud, water – and even more mud - in aid of St Luke’s Hospice.
The Major Series race at Bramham Park in Leeds was designed by former and serving members of the British armed forces.
“Personally, I’ve never seen so much mud in my life and at times I’m sure we all questioned why we were doing it – but none of us would have missed it!” said Nabarro associate Helen Delaney Gill. “It took about three showers and baths to get rid of all the mud after we’d finished.”
