2 DAYS 200 MILES. The Seismic Challenge is a two-day, 200-mile cycling fundraiser to help the San Francisco AIDS Foundation prevent new HIV infections and promote health among people living with HIV. Be a part of the Seismic Challenge as it follows the San Andreas Fault from Fort Bragg in Mendocino County, through the Russian River Valley and across the Golden Gate Bridge into San Francisco. The magnitude of this event will be measured by the hundreds of thousands of dollars that our cyclists will raise to fight HIV.

Join us on October 18th and 19th, 2008 for two demanding cycling centuries and deliver funds that will strengthen the San Francisco AIDS Foundation.
