The Pan-Mass Challenge (PMC) is an annual bike-a-thon that has raised more money for charity than any other single athletic fundraising event in the world. The PMC was founded in 1980 by Billy Starr, who remains the event’s executive director, an annual cyclist, and a fundraiser. The PMC has since raised $598 million for adult and pediatric patient care and cancer research at Dana-Farber Cancer Institute through the Jimmy Fund. The event donates 100 percent of every rider-raised dollar directly to the cause. The PMC generates more than 53 percent of the Jimmy Fund’s annual revenue and is Dana-Farber’s single largest contributor. The PMC has successfully melded support from committed cyclists, volunteers, corporate sponsors and individual contributors. All are essential to the PMC's goal and model: to attain maximum fundraising efficiency while increasing its annual gift. The PMC’s hope and aspiration is to provide Dana-Farber's doctors and researchers with the necessary resources to discover cures for all cancers.
