More than 2,200 cyclists participating in AIDS/LifeCycle — a seven-day ride to raise money for organizations providing HIV-related services — passed through Santa Maria and made their way to Lompoc on Thursday.

During the fifth day of the 545-mile journey from San Francisco to Los Angeles, cyclists began their trek at Preisker Park and ended the day at Ryon Memorial Park.

More than $16.7 million has been raised by the 2019 ride to benefit the Los Angeles LGBT Center and the San Francisco AIDS Foundation, which provide HIV testing, counseling, substance abuse treatment and other services.

In addition to the cyclists, more than 650 volunteer roadies participated to help support the cyclists.

On Thursday, riders dressed in their most creative red outfits to symbolize a red ribbon — the universal symbol for HIV/AIDS awareness.

Outfits for “Red Dress Day” included red-colored dresses, tutus, skirts and other attire.
