All firefighters are held to high standards of physical fitness, not least wildland firefighters. At a minimum, you must be able to complete a three-mile hike without running in no more than 45 minutes while carrying a 45-pound pack. If you want to become a smokejumper, which is a firefighter who parachutes into inaccessible areas, the requirements are stricter. They include being able to complete a 1.5 mile run in less than 11 minutes and a level terrain hike in less than 90 minutes carrying a 110-pound pack.
