A new group that call themselves the "Mustache Riders" took on their first charity ride by wearing mustaches and riding their bicycles on San Francisco's rainy Sunday afternoon to spread awareness and raise charity for prostate and testicular cancer.

And they didn't discriminate--ladies also participated and wore stick-on mustaches too.

The occasion for the ride was Movember, "an annual, month-long celebration of the moustache, highlighting men's health issues - specifically prostate and testicular cancer," according to the Movember's Web site.

All of the money raised for this charity will go to Movember. The Mustache Riders already raised just under $1,000 and hope to raise over $1,000 by Tuesday, according to Theodore Cincotta, president of the Mustache Riders.

"We were looking for different charities to donate to," Cincotta, 33, said. "It's about growing mustaches, which we're all about anyways, so it's a no-brainer."

"It's more for awareness, than actual money," Cincotta added.

Prostate cancer is the second leading cause of cancer death in American men behind lung cancer, according to the American Cancer Society. In 2009, nearly 27,360 men and about 380 men died from prostate and testicular cancer respectively, according to the National Cancer Institute.

The Mustache Riders started at the Ferry Building on the Embarcadero and made stops throughout the city, including Union Square, Civic Center and the Panhandle.

The ride was scheduled to end at Golden Gate Park, but didn't due to the rain.

The ride began with a quick initiation into the group--a hand-shake, high-five and hug with a stranger.

The turnout started with around ten participants, but more cyclists showed up along the way. By the end of the event, nearly 20 people were riding as a group.

The Mustache Riders started as a social outlet for people--with the goal of meeting people who also ride bikes. The Riders have already done six rides, ranging from three to 50 participants each time.

Many participants heard about the event through Facebook.

"Theo is a Facebook buddy and told us it was going to happen," said 33-year-old Oakland resident Margie Valdes, who also participated in the event. "It was for a good cause, so it's cool."

"It's kind of like fun and kooky," said San Francisco resident and freelance graphic designer Jackie Keh, who also participated. "It's fun to ride around and meet cool people. It's also a fun way to get a little exercise."
