The 2025 Green Mountain Iron Dog will be held on September 27th this year. The Iron Dog is an obstacle course race, where runners complete an approximate 1.5 mile course designed to simulate a real-world deployment for Police K9 teams. The course is filled with challenges which often include walls, swamps, hills, guard rails, water crossings, shooting (pellet guns), smoke filled houses, and more.
The course is open to civilian, Police, and Military teams.
