The Habitat Bicycle Challenge (HBC) was a nine-week, student-led bicycle trip undertaken to raise funds for Habitat for Humanity of Greater New Haven and to increase awareness of Habitat for Humanity in general. Occurring annually from 1995 to 2007, the trip traversed the United States from the East Coast to the West Coast. Co-Founded in 1994 by Yale University students Antony Brydon and Tina Teresa Pihl, the original Habitat Bicycle Challenge featured eight riders bicycling from New Haven to San Francisco, California in the summer of 1995. By the time the final ride took place in 2007, HBC attracted about 90 participants a year and had grown to include two additional routes, one ending in Portland, Oregon and the other ending in Seattle, Washington. Even as it grew, HBC retained its origins as a student-run organization, with a core group of twelve leaders organizing every aspect of the three trips, from planning routes to securing corporate sponsorships. Sponsors included Green Mountain Gringo Salsa, Clif Bar, Cannondale, Energy Brands, Bear Naked, and Mortgage Lenders Network, among others.
