WATCH: HIV-Positive Pedalers Get DirtyFit on the Road With Davey Wavey

Thousands of cyclists and volunteer "roadies" on a 545-mile journey from San Francisco to Los Angeles will partake in "Red Dress Day," an over-the-top and fun  AIDS/LifeCycle tradition where cyclists wear a red dress, representing a red AIDS-awareness ribbon, on wheels.

Continuing this mission to reduce new HIV infections and improve the quality of life for people living with HIV or AIDS, YouTuber Davey Wavey has partnered with Positive Pedalers on the photo campaign, END STIGMA, to show that HIV-positive people are thriving with a positive status, not despite it. Comprised of repurposed bike parts and fabulous red costume, the images expand upon what "Red Dress Day" means for the riders on this inspiring and challenging ride through Callifornia.

"During my first ride, I noticed the big plus symbol on the PosPed's jerseys and their tagline, Eliminating stigma through our positive public example," said Wavey. "I was moved and impressed. Instead of surrendering to shame and stigma and hiding, these brave individuals are loudly saying, 'Here I am!' And showing the world that they're not just surviving, but thriving."
