The Pan-Mass Challenge is an annual bike-a-thon and a pioneer of the athletic fundraising industry that today raises more money for charity than any other single event in the country. The organization was founded in 1980 and has since raised $303 million for cancer research and treatment at Dana-Farber Cancer Institute through its Jimmy Fund. The PMC is a model of fundraising efficiency. The PMC donates 100 percent of every rider-raised dollar directly to the cause. In 2010, the PMC generated 60 percent of the Jimmy Fund’s annual revenue and it was Dana-Farber’s single largest contributor. Over 230,000 individual contributions were made to last year’s fundraising campaign. In 2011, PMC cyclists will ride with the goal of raising $34 million for Dana-Farber.
