20 Pics of AIDS/LifeCycle Day 3: Quadbusters, BBQ, Gus Kenworthy

Cyclists crushed the challenging "Quadbuster" on Day 3, in which the steepest part of the climb ascends more than 800 feet and reaches a maximum elevation of about 1,500 feet.

Our generous participants forked over $70,000 -- a record amount -- for a BBQ lunch hosted by students and teachers at Bradley (population: 1,048) to help pay for some of the school's programs. The school even concocted the "$100 Burger Club": for $100 each, participants received five-star dining treatment with table service inside an air-conditioned room.

AIDS/LifeCycle is a fully supported, seven-day, 545-mile bike ride from San Francisco to Los Angeles, co-produced by and benefiting the San Francisco AIDS Foundation and the Los Angeles LGBT Center. The event raises awareness about the ongoing HIV/AIDS epidemic and funds services such as HIV testing, prevention, care, and much more.

Since 1993, when the ride began as a for-profit event called "California AIDS Ride," participants have raised more than $200 million and completed more than 42,000 journeys on bikes from San Francisco to Los Angeles.
