It will be a case of mud, sweat and cheers when 1800 people try to conquer Rotorua's Tough Guy and Gal Challenge tomorrow.
After the kids had their turn at Rotorua's Lakes Ranch today tomorrow is the chance for adults to bring their bag of dirty tricks to the course with 1800 people scrambling to sign up for the 6km and 12km events.
New mud pits have been added to this year's event, said race director Murray Fleming.
He believes it is the quality of the course as well as the enthusiastic team of volunteers that have kept competitors coming back over the past 14 years. Next Friday, 1000 secondary school children from Palmerston North to Waikato will put themselves up for punishment - some of them attempting NCEA credits in the process.
