AIDS Walk Los Angeles is now in its 33rd year of raising money to help people in LA County.
ABC7 is a sponsor of the event.
The annual 10-K raises money for AIDS Project LA Health and dozens of local HIV service organizations.
Since it started in 1985, the LA walk has raised more than $82 million.
The event started with an opening ceremony at the steps of City Hall and then weaved through more than six miles of downtown Los Angeles.
