Firefighters on North Metro Fire 's Wildland Team went back to school Monday.
The firefighters are going through a refresher course to get them ready before fire season starts, North Metro Fire spokeswoman Sara Farris told 7NEWS.
The class started with a run -- a three-mile timed run. Making it even harder, the firefighters had to carry their 45-pound gear backpack.
More than a dozen firefighters are going through the one-day class.
