Ten South King Fire & Rescue firefighters raced to the top of Seattle’s tallest building in full firefighting gear while using a self-contained breathing apparatus on Sunday.

For the annual “Firefighter Stairclimb,” the firefighters raised money for the Leukemia and Lymphoma Society.

Approximately 1,790 firefighters from across the country and the world took part. Last year, over $2.3 million was raised for research. It is expected this year’s funds will surpass last year’s goal.

The firefighters climbed the Columbia Tower’s 69 floors, wearing 60 pounds of equipment, using one bottle of air.

South King Fire & Rescue congratulated all participants in the “grueling event” but noted Brian Moore, who had the fastest time for the team, Christian DuBois, Randy White, team captain Joe Suver, Blair Cottrell, Tyrel Rose, Adam Joyner, Jake Czekanski, James Hampson and Craig Ellenbolt, who had the critical job of changing the firefighters air bottles out on the 40th floor for those who needed it.
