Entries are open for the first-ever Tauranga Boys' College Mud Run Challenge.
The inaugural fundraising event for the school's rugby programme will see competitors tackle a 6km mud course that will include cargo net crawls, a mudslide and a muddy tunnel among other challenges.
The event will start and finish at Pahoia Domain on August 26.
The college's long-serving PE teacher Rodger McBrydie and former Bay of Plenty Steamers blindside Dan Goodwin are organising the event.
