COURSE: The Irvine Lake Mud Run is an approximate +5k course beginning and ending at picturesqueIrvineLake. The course is partially on the road and partially on trails and includes hills; water (no contact with lake anywhere), professionally built obstacles and “eight+” mud pits. You asked for even more mud, you got it! You will get wet and you will get muddy. Be sure to bring towels and a change of clothing.
