SAN FRANCISCO (KCBS) – A group of Bay Area firefighters and first responders had some tired legs on Sunday after participating in an event honoring comrades who lost their lives on 9/11.

The local Sikh community played a big role in helping to put together the annual 9-11 Memorial Stair Climb at the Transamerica Pyramid in San Francisco.

About 250 firefighters, military members and first responders took part in the challenge, going up 48 stories of the building, coming down an elevator and then doing it again.

KCBS’ Chris Filippi Reports:

San Francisco firefighter Greg Collaco helped organize the event, which honors the 343 firefighters who died on 9/11.

“If you look back then how dusty, bloody and horrific it was to today, a beautiful day, tables and t-shirts with red, white and blue and people of all different nationalities coming out here and celebrating,” Collaco said.

More than two dozen people from the Sikh community showed up as well to not only share food with the crowd, but also trying to be more proactive within the community.

The stair climb also paid tribute to San Francisco firefighters Anthony Valerio and Vincent Perez, who died in the line of duty earlier this year.
