As many as 25,000 people gathered in Golden Gate Park Sunday to take part in the city's 25th annual AIDS Walk San Francisco.
Since the first AIDS Walk in 1987, more than $74 million has been raised for Bay Area HIV/AIDS service organizations, according to official totals released by organizers.
Total donations collected by this year's volunteers, sponsors and participants was announced at a post-walk celebration at Sharon Meadow, where the 6.2-mile walk begins and ends.
More than $3 million was raised at the event in 2010.
Opening ceremony speakers included San Francisco Mayor Ed Lee, actress Cloris Leachman, and actor Alan Cumming.
Sen. Mark Leno, D-San Francisco, city Treasurer Jose Cisneros and Supervisors David Chiu, Ross Mirkarimi and Scott Wiener also attended.
