Gisborne Harriers Mud Run is at Maclaurin Farm in Hexton on Sunday, 11 August 2019.
There will be a coffee cart, loud and inspiring music, a sausage sizzle, water to guzzle afterwards and warm showers available.
As a twist, this year's Mud Run dressup theme is "something beginning with letter M or R". Get dressed up as there will be a spot prize for the best dressed!
