Purpose: This challenge teaches true heat management, not just “build a fire and hope.”Your objective is to retain, redirect, and manage heat while staying mostly static—the hardest condition in cold weather. Cold injuries happen after movement stops. This drill exposes weak points in your system. Challenge Objective: Remain comfortably warm for 30–60 minutes with minimal movement, using deliberate control of: - Conduction - Convection - Radiation Rules of the Challenge 1. No constant movement 2. One fire 3. One shelter 4. One insulation solution 5. Time Requirement The Heat Science 1️⃣ Conduction – Heat Lost to the Ground What it is: Heat transfer through direct contact. In the field: If you sit or lie on cold ground, rock, snow, or frozen earth, your body heat is being pulled out of you. Solutions you’re testing - Natural debris (pine boughs, leaves) - Foam pad, pack, bark - Raised bed or platform Failure sign: Cold creeping into hips, lower back, or legs. 2️⃣ Convection – Heat Taken by Moving Air What it is: Heat stripped away by wind or moving air. In the field: Even light wind will steal heat faster than cold air alone. Solutions you’re testing - Shelter orientation - Wind blocks - Terrain use Failure sign: Feeling chilled despite a fire burning. 3️⃣ Radiation – Heat You Can Capture What it is: Heat emitted from your fire in straight lines. In the field: If you can’t feel the fire on your face or chest, you’re wasting heat. Solutions you’re testing - Fire size and distance - Reflector (log wall, rock face, emergency blanket) - Fire height (platform fire) Failure sign: Fire burns well but doesn’t warm you. Pre-Drill Setup (Required) Before starting, record: - Air temperature - Wind conditions - Ground condition (snow, frozen soil, wet leaves) - Clothing layers worn at start - Fire type used - Shelter type used - Insulation material used HEAT MANAGEMENT LOG (Required) Participants must complete at least one full log.
