The Pan-Mass Challenge (PMC) is the nation’s largest single athletic fundraising event, raising more money for charity than any other single event in the United States. Founded in 1980, the PMC has contributed an unprecedented $1.125 billion to Dana-Farber Cancer Institute (DFCI), with 100 percent of all rider-raised funds going directly to DFCI for 20 consecutive years. Each August, more than 6,500 cyclists, supported by 3,500 volunteers, ride across 42 towns on 14 fully supported routes ranging from 25 to 177 miles. Riders commit to raising between $1,000 and $6,000, and on average raise $11,852 per rider, contributing to the PMC’s industry-leading fundraising totals, including $78 million in 2025. The PMC also maintains a Net Promoter Score of 89, placing it among the most admired and trusted events worldwide. The PMC is a year-round ecosystem made up of Ride Weekend, PMC Unpaved, PMC Winter Cycle, and PMC Kids Rides, offering brands continuous participation and visibility. Sponsors reach a deeply engaged, mission-driven audience that includes 33 percent senior-level decision-makers, such as CEOs, founders, portfolio managers, physicians, and executives. PMC support directly advances cancer research and care at Dana-Farber. In recent years, PMC-enabled funding has helped fuel development of more than half of all FDA-approved cancer drugs, expanded clinical trials to over 1,100 active trials, and supported major research facilities, endowed positions, and health equity programs. For brands seeking powerful purpose-driven alignment, year-round touchpoints, and unmatched community goodwill, the PMC delivers one of the most meaningful sponsorship platforms in the country.
