The Arduous Work Capacity Test (AWCT), known informally as the “pack test”, is a U.S. Forest Service physical test for wildland firefighters. The pack test is intentionally stressful as it tests the capacity of muscular strength and aerobic endurance of the firefighter. The pack test may be given as part of the S-130/S-190 basic wildland firefighter course. Requirements: 3-mile hike with 45 lb pack in 45 minutes. No jogging or running.
